Type corresponds to different bit maps.
No matter using it is above-mentioned which kind of the corresponding bit map of data type predetermined is set by the way of, it is each determining
When the T field of the data of limited authority, the corresponding type of the data of the limited authority can be first determined, determining type can at this time
Think one-dimensional or multidimensional, if it is determined that the corresponding type of the data of limited authority is one-dimensional, then from the preparatory fixed of above-mentioned setting
It is directly inquired in the corresponding bit map of data type of justice.If it is determined that the corresponding type of the data of limited authority is more
Dimension, then can inquire every in multidimensional type respectively from the corresponding bit map of data type predetermined of above-mentioned setting
The corresponding bit map of type is tieed up, then the bit map inquired is attached, obtains the T field of the data of limited authority.
Wherein, when merging, for any one of the above set-up mode, the corresponding bit map of multiple types can directly be carried out
Connection.For example, the corresponding bit map of the two types for inquiring the data of limited authority is respectively 010 and 100, then the permission
The T field of limited data is 010100.
Optionally, for above-mentioned second of set-up mode, in addition to the corresponding bit map of multiple types directly can be carried out
Outside the mode of connection, if in above-mentioned second of set-up mode on the corresponding bit of every kind of data type predetermined
Value is 1, and the value on other bits is 0 to indicate the corresponding bit map of every kind of data type predetermined, then is inquiring
To after the corresponding bit map of each type of the data of limited authority, the bit map inquired can be subjected to union,
T field of the obtained operation result as the data of limited authority.Wherein, 1 corresponding authority of each of the operation result is limited
One of data type.For example, the data of limited authority include the 1st kind of data type and the 3rd kind of data type, inquire
The 1st kind of corresponding bit map of data type be 0001, the 3rd kind of corresponding bit map of data type is 0100, then will
After 0001 and 0100 carries out union, obtained operation result is 0101, due to 1 corresponding 1st bit in the operation result
Position and the 3rd bit, then it represents that the type of the data of the limited authority includes the 1st kind of data type and the 3rd kind of data type, with
The practical type for including of the data of the limited authority is identical.
Optionally, if in above-mentioned second of set-up mode on the corresponding bit of every kind of data type predetermined
Value be 0, the value on other bits is 1 to indicate the corresponding bit map of every kind of data type predetermined, then is looking into
After the corresponding bit map of each type for asking the data of limited authority, the bit map inquired can be carried out and be transported
It calculates, T field of the obtained operation result as the data of limited authority.Wherein, 0 corresponding authority of each of the operation result by
One of data of limit type.For example, the data of limited authority include the 1st kind of data type and the 3rd kind of data type, inquiry
The 1st kind of corresponding bit map of data type arrived is 1110, and the 3rd kind of corresponding bit map of data type is 1011, then will
1110 and 1011 carry out with the operation result after operation, obtained being 1010, due to 0 corresponding 1st bit in the operation result
Position and the 3rd bit, then it represents that the type of the data of the limited authority includes the 1st kind of data type and the 3rd kind of data type, with
The practical type for including of the data of the limited authority is identical.
Outside the method for determination of the T field for the data for having introduced limited authority, for the ease of searching, in subordinate ordered array
The data of Buffer_Length, TLV_Buffer also can be used binary system and are indicated.For example, Buffer_Length can be adopted
With 200 bits, then the length of TLV_Buffer is also 200 bits.Due to the Limits each limited authorities of expression
The corresponding authority information of data, and the authority information can there are many, including but not limited to send the permission of message, reception disappears
The permission of breath, the permission for adding good friend etc..And since the data of a limited authority can also correspond to multiple authority informations, because
This, is managed authority information for the ease of subsequent, the data in Limits can equally be used binary bits bitmap
It is indicated, specific representation includes but is not limited to two kinds.For example, Limits corresponds to 6 bits, each bit is corresponding
One permission, specific value can be replaced with 0 and 1, if the numerical value of which bit is 1, it is corresponding to represent the bit
Limited authority.For example, TLV_Buffer(1) in data do not send the permission of message, and the permission for sending message exists
Third bit is corresponded in Limits, then numerical value of the data in Limits on third bit is 1.
It should be understood that the length of the data of the limited authority stored in TLV_Buffer can according to need and be set
Fixed, the length of the TLV_Buffer in each array element can be the same or different, the data stored in TLV_Buffer
Length also can be the same or different.Since the data of limited authority are using TLV format, but the data of each scene
Dimension and type difference, cause the TLV_Buffer in each array element elongated, more troublesome for the processing of elongated data,
If when subsequent lookup needs to calculate the current length of each array element directly with the storage of elongated data, lead to inquiry
Complexity increases.For this purpose, improving inquiry velocity in order to simplify subsequent query process, being used in method provided in this embodiment
The TLV_Buffer of fixed length.That is, the length of the TLV_Buffer in each array element is fixed length, but every number
The length of the data of the limited authority of TLV_Buffer storage in group element can be the same or different.For example, every number
The length of TLV_Buffer in group element is 100 bits, TLV_Buffer(1) in store is instant messaging number, deposit
Store up occupied 86 bits in space；TLV_Buffer(2 what is stored in) is IP address, occupied 96 bits of memory space.
It can be seen that although the length of the TLV_Buffer in each array element is 100 bits, the TLV_ in each array element
The length of the data of Buffer storage can be Length discrepancy.
202: obtaining the corresponding type bit map of each dimension data of limited authority, and the limited each dimension that defines the competence
The corresponding permission index information of data, each dimension of each dimension data of limited authority corresponding permission index information and limited authority
Degree is corresponding according to the storage region in permissions data；
Wherein, by above-mentioned steps it is found that the available TLV format of the data of each limited authority is stored, and T, L and V
Field can be indicated using binary bit again, i.e. the corresponding type bit map of each dimension data of limited authority
For a string 0 and 1 code.The data that each limited authority has then been stored in the permissions data of above-mentioned steps building are corresponding
Type bit map, then the step, can be direct in the corresponding type bit map of each dimension data for obtaining limited authority
It is inquired from the permissions data obtained in above-mentioned steps 201.
Further, it is determined that when the corresponding permission index information of each dimension data of limited authority, the permission index information
For identifying storage location of each dimension data of limited authority in permissions data, the start index information including storage location
With end index information, then the corresponding permission index information of each dimension data of the limited authority can be each dimension of limited authority
Degree is according to the corresponding address of storage region in permissions data, therefore, the corresponding permission rope of each dimension data of limited authority
Fuse breath is corresponding with storage region of each dimension data of limited authority in permissions data.For example, if permissions data obtains
It is stored in memory after taking, then the start index information in the corresponding permission index information of each dimension data of the limited authority can
Think the initial memory address of each dimension data of limited authority in memory, the corresponding power of each dimension data of the limited authority
Limiting the end index information in index information can be the end storage address of each dimension data of limited authority in memory.
203: sequentially storing the corresponding type bit map of each dimension data and permission index information of limited authority, obtain
Permission index data；
For the step, the corresponding type bit map of each dimension data and permission index letter of limited authority are sequentially stored
After breath, obtained permission index data can be stored with the mode of structural body.And for the ease of subsequent lookup, permission rope
Argument other than the corresponding type bit map of each dimension data of storage limited authority and permission index information, may be used also in
Number information is indexed with storage, to accelerate subsequent search speed.Wherein, permission index data is stored in a manner of structural body
When, the first character section of structural body can be used to record current existing index number information, and field later is with the side of array
Formula is used to store the corresponding type bit map of each dimension data and permission index information of limited authority.
The structure of permission index data in order to facilitate understanding is such as with the structure of permission index data in conjunction with above content
For shown in the following table 9:
Table 9
In table 9, wUsedNum is current existing index number information in permission index data, has recorded permission index
The number of the permission index information stored in data.DwTypeBitMap (m) represents the corresponding class of data of m-th of limited authority
Type bit map.DwStartIndex (m) is that the starting in the permission index information of the data of m-th of limited authority indexes letter
Breath.DwEndIndex (m) is the end index information in the permission index information of the data of m-th of limited authority.Wherein, m is
Positive integer.
The position wUsedNum is the first field of permission index data, dwTypeBitMap (0), dwStartIndex

205: the type bit map of multidimensional data is obtained according to the data type information of every dimension data；
Specifically, the step is in the type bit map for obtaining multidimensional data according to the data type information of every dimension data
When, since the data type information of every dimension data can be indicated with the corresponding type bit map of every dimension data, then multidimensional
The corresponding type bit map of every dimension data can be attached to obtain by the type bit map of data.
Wherein, if the data type information of every dimension data in the step corresponds to the first set-up mode in step 201,
Then the data type information of every dimension data is directly attached.For example, the multidimensional data of permission to be checked is two dimensions
According to respectively corresponding Instant Messenger signal and IP address, the corresponding data type information of Instant Messenger signal is 010, and IP address is corresponding
Data type information is 100, then the type bit of the two-dimensional data got according to the data type information of every dimension data
Figure is 010100.
Optionally, if the data type information of every dimension data in the step corresponds to second of setting side in step 201
Formula, the type bit map in addition to multidimensional data can be obtained by the way that the data type information of every dimension data to be directly attached
Mode outside, if with the corresponding ratio of every kind of data type predetermined in second of set-up mode in above-mentioned steps 201
Value on special position is 1, and the value on other bits is 0 data type information to indicate every dimension data, then the step can will be more
The data type information of every dimension data in dimension data carries out union, to obtain the type bit map of multidimensional data.Its
In, a kind of corresponding data type of each of operation result 1.Optionally, if second of setting side in above-mentioned steps 201
With the value on the corresponding bit of every kind of data type predetermined for 0 in formula, the value on other bits is 1 to indicate every
The data type information of dimension data, then can by the data type information of every dimension data in multidimensional data carry out and operation, thus
Obtain the type bit map of multidimensional data.Wherein, the corresponding a kind of data type of each of operation result 0.
In order to make it easy to understand, with the value on the corresponding bit of every kind of data type predetermined for 1, other bits
On value be 0 set-up mode be illustrated.For example, the multidimensional data of permission to be checked is two-dimensional data, respectively correspond
Instant Messenger signal and IP address, the corresponding data type information of Instant Messenger signal are 001, the corresponding data type information of IP address
It is 010, then when obtaining the type bit map of two-dimensional data according to the data type information of every dimension data, 001 and 010 is carried out
Union, obtained operation result are the type bit map that 011,011 is the two-dimensional data.Due to the class of the two-dimensional data
Corresponding 1st bit in the 1 of type bit map and the 2nd bit, then it represents that the data type of the multidimensional data includes the 1st kind of data
Type and the 2nd kind of data type, the data type for including practical with the multidimensional data of permission to be checked are identical.
206: the type bit in permission index data obtained according to the type bit map of multidimensional data and in advance
Scheme the sub-portfolio type bit map of determining multidimensional data, and inquires sub-portfolio type bit map pair in permission index data
The permission index information answered；
Specifically, the type bit in permission index data obtained according to the type bit map of multidimensional data and in advance
Bitmap can determine the sub-portfolio type bit map of multidimensional data, in the sub-portfolio type bit map for determining multidimensional data
Afterwards, the corresponding permission index information of sub-portfolio type bit map can further be inquired.
Wherein, the type bit in permission index data obtained according to the type bit map of multidimensional data and in advance
Scheme to determine that the sub-portfolio type bit map of multidimensional data can be carried out according to the following two kinds mode:
The first method of determination: by be worth for 1 bit correspond to a kind of data type for, by the type ratio of multidimensional data
The type bit map stored in special bitmap and permission index data successively carries out and operation, if operation result and permission index number
It is identical according to any kind bit map of middle storage, then using the type bit map as the sub-portfolio type bit of multidimensional data
Bitmap.
For example, by taking the type bit map of multidimensional data is 00011 as an example, and first stored in permission index data
Type bit map is 00010, and second type bit map is 01001, and so on.By the type bit of multidimensional data
Figure is successively done with the type bit map stored in permission index data and operation, and 00011 does with 00010 and is with operation result
00010, the operation result is identical as first type bit map 00010, then illustrates store in permission index data first
A type bit map 00010 is the sub-portfolio type bit map of multidimensional data.
Second of method of determination: by be worth for 0 bit correspond to a kind of data type for, by the type ratio of multidimensional data
The type bit map stored in special bitmap and permission index data successively carries out union, if operation result and permission index number
It is identical according to any kind bit map of middle storage, then using the type bit map as the sub-portfolio type bit of multidimensional data
Bitmap.
For example, by taking the type bit map of multidimensional data is 11100 as an example, and first stored in permission index data
Type bit map is 11101, and second type bit map is 10110, and so on.By the type bit of multidimensional data
Figure successively does union with the type bit map stored in permission index data, and 11100 do with 11101 and are with operation result
11101, the operation result is identical as first type bit map 11101, then illustrates store in permission index data first
A type bit map 11101 is the sub-portfolio type bit map of multidimensional data.
Certainly, the type bit in the permission index data obtained according to the type bit map of multidimensional data and in advance
Bitmap determines that the mode of the sub-portfolio type bit map of multidimensional data in addition to above two method of determination, can also use other
Method of determination, the present embodiment are not especially limited this.
It should be noted that during specific implementation, a type bit map in the index data that defines the competence is
After the sub-portfolio type bit map of multidimensional data type bit map, the sub-portfolio class can be inquired in permission index data
The corresponding permission index information of type bit map, and further inquiry is done into permissions data according to permission index information, without
With all sub-portfolio type bit maps of the determining multidimensional data.
207: being looked into from the permissions data obtained in advance according to the corresponding permission index information of sub-portfolio type bit map
Corresponding authority information is ask, and determines the permission of multidimensional data according to the authority information inquired；
Specifically, after the sub-portfolio type bit map that multidimensional data is determined in above-mentioned steps, according to determining subgroup
Close the data that multidimensional data is split into sub-portfolio type by the data type in type bit map.According to sub-portfolio type bit
The data storage location of limited authority in bitmap corresponding permission index information positioning permissions data, in permissions data permission by
The data of limited authority identical with the data of sub-portfolio type after fractionation are searched within the scope of the data storage location of limit.If
The data that limited authority identical with the data of sub-portfolio type after fractionation is found in permissions data, then inquire this and find
Limited authority the corresponding authority information of data, and determine according to the authority information inquired the permission of multidimensional data.If
The data for not finding limited authority identical with the data of sub-portfolio type after fractionation in permissions data, then execute step again
Rapid 206 and step 207, with the type ratio in the permission index data that obtains according to the type bit map of multidimensional data and in advance
Special bitmap determines another sub-portfolio type bit map of multidimensional data, and continues to inquire corresponding authority information, until power
Until the type bit map whole retrieval stored in limit index data finishes.
Wherein, it is searched within the scope of the data storage location of limited authority in permissions data and the sub-portfolio type after fractionation
The identical limited authority of data data when, since the data in permissions data are to be stored in an orderly manner, because
This, which can be realized with binary chop algorithm, to improve the efficiency of lookup.It is, of course, also possible to be looked into using other
Algorithm is looked for, the present embodiment is not especially limited this.
It should be noted that since current existing index being also stored in permission index data in permission index data
Number information, therefore, by the type bit map stored in the type bit map of multidimensional data and permission index data successively into
When capable and operation or union, progress and operation can be determined according to existing index number information current in permission index data
Or the number of the type bit map of union.For example, can define the competence index number if the index number information is 6
6 type bit maps are stored in, are successively read in permission index data type in the 7th field of second field value
The data of bit map, without reading other fields in permission index data again, so as to improve search efficiency.
Further, when through the above steps 201 establish permission index data and permissions data to step 203 after, this
The method that embodiment provides further includes the process being updated to the data in permission index data and permissions data, specific to update
Process can execute before or after the query process of above-mentioned steps 204 to step 207, about to permission index data and permission
The time that data in data are updated, the present embodiment are not specifically limited.For ease of description, the present embodiment is only to hold
The query process of row step 204 to step 207 carries out the data updating process in permission index data and permissions data later
Example carries out detailed explanation to the data updating process in permission index data and permissions data, specifically sees below step
Rapid 208:
208: obtaining data to be updated and update operation information, data to be updated are believed including at least corresponding data type
Breath, data length information and data content information；
Specifically, the present embodiment is not defined the mode for obtaining data to be updated and update operation information, equally not
The content of data to be updated and update operation information to acquisition is defined.In concrete application, when user does one by terminal
After operation, collect the related data and operation information of this operation, using the related data that is collected into as get to
More new data, using the operation information being collected into as the update operation information got.
209: the type bit map of data to be updated, and the power of inquiring are determined according to the data type information of data to be updated
Limit the type bit map that whether there is data to be updated in index data；
Specifically, include corresponding data type information in data to be updated, this can be determined according to data type information
Explanation is explained in detail in the type bit map of data to be updated, detailed process in step 205, and details are not described herein again.Really
It, can be according to the type bit map of data to be updated in permission index data after the type bit map of fixed data to be updated
It is inquired in all types bit map of storage, whether there is the type ratio of data to be updated in the index data that defines the competence
Special bitmap.
210: according to the content in query result and update operation information renewal authority index data and permissions data.
For the step, according to query result and update in operation information renewal authority index data and permissions data
Hold, including but not limited to following three kinds of situations:
The first situation: if query result is the type bit map that data to be updated are not present in permission index data,
And update operation information and carry the corresponding authority information of data to be updated, then number to be updated is stored in the corresponding position of permissions data
According to and corresponding authority information；It is deposited in permission index data according to data to be updated and the storage location of corresponding authority information
Store up data to be updated type bit map and corresponding permission index information.
In the first case, the type bit map of data to be updated is not present in permission index data, then illustrates this
When update operation be that data update operation, update operation information and carry the corresponding authority information of data to be updated.Therefore, it is necessary to
A block space is newly opened up in permissions data to be used to store data to be updated and corresponding authority information.Due in permissions data
Data sequentially store, therefore, the space newly opened up can according in the data and permissions data of update it is stored its
The size orders of his data determines.
After carrying out the update of data and authority information to permissions data, it is also necessary to the permission in permission index data
Index information is updated.Firstly, it is necessary to add an index entry, the type bit of the index entry in permission index data
Figure is the type bit map of data to be updated, and corresponding permission index information is data to be updated and corresponding permission letter
The storage location in permissions data is ceased, according to other permission index informations in the permission index information and permission index data
The permission index information is inserted into corresponding position in permission index data by size relation.
Second situation: if query result be permission index data in there are the type bit maps of data to be updated, and
It updates in operation information and carries the corresponding authority information of data to be updated, then inquire data to be updated in permission index data
The corresponding permission index information of type bit map；Determine the memory block of the permission index information corresponding authority data inquired
Domain, and search in storage region with the data of the consistent limited authority of data to be updated, if found and data to be updated
The data of consistent limited authority are then looked into according to the corresponding authority information update of the data to be updated carried in update operation information
The authority information corresponding with the data of the consistent limited authority of data to be updated found.If do not found and data to be updated
The data of consistent limited authority are then inserted into data to be updated and corresponding authority information in the corresponding position of storage region, and
Adjust the storage location of other content in permissions data；It is updated according to data to be updated and the storage location of corresponding authority information
The corresponding permission index information of type bit map of data to be updated in permission index data, and according to permission number adjusted
Permission index information corresponding in permission index data is updated according to the storage location of middle other content.
In second situation, there are the type bit maps of data to be updated in permission index data, this means that power
May there be data identical with data to be updated in limit data.If there being number identical with data to be updated in permissions data
According to being updated to the permission of multidimensional data identical with data to be updated in permissions data at this time.If in permissions data
Data not identical with data to be updated, then be updated to the data in permissions data at this time.Therefore, in second of feelings
It is divided into two kinds of situations again in condition, specifically:
The first situation: the permission of multidimensional data identical with data to be updated in permissions data is updated；Specifically
Ground is found in permissions data after multidimensional data identical with data to be updated, according to update operation information in carry to more
The corresponding authority information of new data, the authority information corresponding with the data of the consistent limited authority of data to be updated that will be found
It is updated.
Wherein, authority information is updated can be increase to a few limited permission or reduce at least one by
The permission of limit, the present embodiment do not make the content for updating the corresponding authority information of data to be updated carried in operation information specific
It limits.The specific update mode of authority information can be determined according to the representation of authority information, and the present embodiment believes permission
The update mode of breath is not especially limited, and is explained in detail about having in the expression way above-mentioned steps 202 of authority information
Bright, details are not described herein again.
Second case: the data in permissions data are updated.Specifically, it is inserted into the corresponding position of storage region
Data to be updated and corresponding authority information, and adjust the storage location of other content in permissions data；According to data to be updated
And in the storage location renewal authority index data of corresponding authority information data to be updated the corresponding power of type bit map
Index information is limited, and according to the storage location of other content in permissions data adjusted to corresponding power in permission index data
Limit index information is updated.
When it is implemented, being first inserted into data to be updated and corresponding authority information in the corresponding position of storage region.Wherein,
The position of data to be updated and the insertion of corresponding authority information can be determined with the following method:
The data of limited authority and corresponding authority information store Shi Douyong binary system to be stored, then in storage region
The two links together as a string of binary zeros, 1 code, which represents a specific numerical value.Class according to this
It pushes away, the data of corresponding every a pair of of the limited authority of a seed type bit map and corresponding authority information are all corresponding in permissions data
A specific value, be ranked up according to the size of each numerical value, formed an orderly sequence.Data and correspondence to be updated
Authority information equally correspond to a binary numeral, according to the numerical value in ordered sequence sort use binary chop it is true
The position of fixed data to be updated and the insertion of corresponding authority information.It is, of course, also possible to determine data to be updated using other methods
And the position of corresponding authority information insertion, the present embodiment are not especially limited this.
Due to insert new limited authority data and corresponding authority information, data and correspondence to be updated
The data of the subsequent limited authority in authority information insertion position and the storage location of corresponding authority information can all change
Become, thus needs to adjust the storage location of other content in permissions data according to the actual situation.Simultaneously as its in permissions data
He is changed the storage location of content, and therefore, it is necessary to the storage locations according to other content in permissions data adjusted
Permission index information corresponding in permission index data is updated.
For above-mentioned second situation, more according to the corresponding authority information of data to be updated carried in update operation information
After the authority information corresponding with the data of the consistent limited authority of data to be updated newly found, further includes:
If updated authority information show in permissions data with the data of the consistent limited authority of data to be updated not by
Limit, then deleted from permissions data with the data of the consistent limited authority of data to be updated and corresponding authority information, and adjust
The storage location of other content in permissions data；
By permission index information corresponding with the data of the consistent limited authority of data to be updated in permissions data from permission
It is deleted in index data, and according to the storage location of other content in permissions data adjusted in permission index data
Corresponding permission index information is updated.
Specifically, in the operation being updated to authority information, if the operation updated is reduction, at least one is limited
Permission, when all limited permissions of the data of the limited authority are all eliminated, then the data of the limited authority are not any
Restricted rights, at this time the data of the limited authority do not have in permissions data then storage meaning, it is therefore desirable to by the permission by
The data of limit are deleted from permissions data.It is deleted and data of the consistent limited authority of data to be updated and corresponding from permissions data
Authority information after, the storage location of the data of the limited authority and the subsequent other content of corresponding authority information needs to carry out
Before move.Wherein, the data of the other limited authorities of other content reference and corresponding authority information, need to adjust in permissions data
The storage location of other content.
Since the data of permissions data others limited authority and the storage location of corresponding authority information are changed,
Therefore, it is necessary to according to the storage location of other content in permissions data adjusted to permission rope corresponding in permission index data
Fuse breath is updated.
The third situation: if query result be permission index data in there are the type bit maps of data to be updated, and
It updates to carry in operation information and deletes instruction, then the type bit map for inquiring data to be updated in permission index data is corresponding
Permission index information；Determine the storage region of the permission index information corresponding authority data inquired, and in storage region
The data with the consistent limited authority of data to be updated are searched, if finding the number with the consistent limited authority of data to be updated
According to, then according to update the deletion that carries in operation information indicate to delete from permissions data with the consistent permission of data to be updated by
The data of limit and corresponding authority information, and adjust the storage location of other content in permissions data；Renewal authority index data
In data to be updated the corresponding permission index information of type bit map, and according to other content in permissions data adjusted
Storage location permission index information corresponding in permission index data is updated.
Wherein, when the storage location of other content is adjusted in permissions data, other contents refer to other permissions
Limited data and corresponding authority information can be carried out according to the specific storage mode of the data of limited authority in permissions data
Adjustment is stored in a manner of array as worked as the data of limited authority and corresponding authority information in permissions data, deletes one
After the data of a limited authority and corresponding authority information, need all to move subsequent other contents forward one storage position
It sets.In this way, the storage location that will lead to the limited data of subsequent authority and corresponding authority information changes, therefore, it is necessary to
According to the storage location of other content in permissions data adjusted to permission index information corresponding in permission index data into
Row updates.
If the data of the corresponding limited authority of a seed type bit map are complete in permissions data during deleting data
Portion deletes and finishes, in addition to that need to adjust because in permissions data other than the storage location of other contents, also wanting caused by deleting data
The type bit map corresponding authority index entry in permission index data is deleted.After deleting a permission index entry, need
Subsequent permission index entry is moved forward, so that the storage location to updated permission index information be needed to re-start adjustment.
Method provided in this embodiment realizes multidimensional data by introducing type bit map and permission index information mechanism
Permission inquiry, make entire query process without complicated functional operation, thus compared to by the way of Hash table search access right,
Improve the permission search efficiency of multidimensional data.
