Description
Technical field
The present invention relates to the database design field, relate in particular to a kind of multi-chart information initializing method of database.
Background technology
In the database application field, under the bigger situation of quantity of information, employing is put into the method that different database tables is preserved respectively after a complete information is divided into a plurality of parts usually, and above-mentioned different database table is commonly called database multi-list.For the ease of inquiry, when beginning to start in system usually, the database multi-list related to this system carries out initialization, promptly by reading database multi-list, the each several part information that is distributed in the database multi-list is extracted, thereby obtain a complete information record.
In existing multi-chart information initializing method of database, usually the data volume of being preserved with each table is a foundation, and the database table of data volume maximum is defined as master meter, and other database table except that master meter is defined as inferior showing.The database multi-list of being formed with table 1 and table 2 is an example, because the data volume that comprises is bigger than the data volume in the table 2 in the table 1, therefore table 1 is defined as master meter, table 2 is time table.

Table 2
Referring to Fig. 1, determined that the existing database multi-chart information initializing method behind master meter and time table may further comprise the steps:
Step 101. reads master meter information, forms the master meter record set.
In this step, use the system of database multi-list at first master meter to be read, each row in the master meter as a record, is formed the master meter record set in self EMS memory.For the master meter shown in the table 1, the formed master meter record set of this step comprises and putting in order and identical 8 records of table 1, all contains information such as device name, version and use agreement in every record.
Step 102. reads first record in the master meter record set.
In this step, use the system of database multi-list from the master meter record set that is kept at internal memory, to obtain article one record.For the master meter record set that is formed by table 1, first that reads this moment is recorded as: device name Dev1, a version V100, use agreement SNMP.Wherein, for the system that uses database multi-list, Dev1 and V100 are Given informations, and SNMP then is a unknown message.
Step 103. reads the information in each time table according to the current record in the master meter record set.
Owing to include unknown message in the current master meter record, and the incidence relation between each table of setting when setting up database multi-list as can be known, above-mentioned unknown message is present in each time table, therefore in this step with the unknown message in the current master meter record as querying condition, utilize query sentence of database to inquire about each time table successively.When system found the concrete implication of above-mentioned unknown message by database query operations from table 2 after, database multi-list as Query Result, returned to internal memory with the concrete implication of the unknown message that found.
For example, in the formed master meter record set of table 1, when current record is in this master meter record set first record, SNMP is a unknown message, then with SNMP as the querying condition that is included in the query statement, his-and-hers watches 2 read, then after the implication that gets access to SNMP is Simple Network Management Protocol, to internal memory return data storehouse multi-table query result.
The information that comprises in time table that step 104. writes down current master meter and read is assembled into a complete record.
Having finished this to after the reading of inferior table, use the system of database multi-list that the Given information in the current master meter record is combined with the implication of the unknown message that gets access to from inferior table, form a complete record.Be example still with first of table 1 record and table 2, the Simple Network Management Protocol that in this step database multi-list is returned to internal memory is updated among the SNMP in first record of table 1, and form the complete documentation that thes contents are as follows: device name Dev1, version V100, use agreement are Simple Network Management Protocol.
Step 105～106. judge that whether current master meter record is the tail record in the master meter record set, if, then finish notebook data storehouse multi-chart information initializing flow process, otherwise, turn to next the bar record in the master meter record set, and return execution in step 103.
If current master meter record is not the tail record in the master meter record set, then represent also to have the record that is not read in the master meter record set, and the unknown message in the above-mentioned record that is not read awaits obtaining from each time table; If current master meter record is the tail record in the master meter record set, then reading of master meter record set and each time table finished in expression, and formed all required complete documentations, promptly finished the database multi-list information initializing.
Above-mentioned steps 101 to 106 has been formed existing database multi-list information initializing process.Tentation data storehouse multilist is made up of master meter and n table, and wherein the line number of master meter is m.By above steps as seen, when forming the master meter record set, each row in the master meter forms a master meter record, promptly forms the master meter record set that comprises m bar record; And whenever read a master meter record, and all to from database, all time tables be read once, promptly read time database manipulation of table and carry out (m * n) inferior altogether; Consider again when forming the master meter record set the reading of master meter, then need the number of times of reading database to be: (1+mn) inferior for finishing the database multi-list information initializing.In addition, suppose to read the time that master meter consumes from database is k at every turn
1Second, read the inferior time of showing to be consumed from database is k at every turn
2Second, the time of then finishing the database multi-list information initializing is: (k
1+ mnk
2) second.
For table 1 and table 2, have 8 row, i.e. m=8 in the master meter; Inferior table has only one, i.e. n=1 then finishes the database multi-list information initializing and needs the number of times of reading database to be:
(1+8 * 1)=9 times.
The time that suppose to read table 1 again needs at every turn is 0.05 second, and the time of at every turn reading table 2 is 0.02 second, and then the time of database multi-list information initializing is: (0.05 * 1+8 * 1 * 0.02)=0.21 second.
From above-mentioned analysis as can be known, the shortcoming of existing multi-chart information initializing method of database is: the number of, inferior table more when the line number that master meter comprises more for a long time, make reading database the time number of times long and reading database of consumption more, the time of therefore finishing the database multi-list information initializing is long, speed is slow, efficient is lower.

Embodiment
For making purpose of the present invention, technical scheme clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.
The present invention is a kind of multi-chart information initializing method of database, and its basic thought is: at first, the information in each time table is read in the internal memory; Then, read the information in the master meter, and in internal memory, form the master meter record set; Then, according to the incidence relation between unknown message in the master meter record set of setting up in advance and time table information, with the unknown message in the described master meter record set is index, by described incidence relation, inferior table information that retrieval is associated with this unknown message in the internal memory, and the Given information in the described master meter record set and the relevant inferior table information that retrieves are assembled into the complete documentation of database multi-list information
The database multi-list that still constitutes with table 1 and table 2 is an example below, and multi-chart information initializing method of database of the present invention is described.
The present invention was a foundation with the data volume of being preserved in each table before the database multi-chart information is carried out initialization, pre-determined master meter and time table.For table 1 and table 2,, determine that therefore table 1 is that master meter, table 2 are time table because the data volume that comprises in the table 1 is bigger than table 2.
Referring to Fig. 2, multi-chart information initializing method of database of the present invention may further comprise the steps:
Map is a kind of list formula set, and it comprises a plurality of element units of being made up of key word (Key) and corresponding element value (Value) thereof (Element).Map uses Hash (Hash) algorithm to carry out self memory and retrieval, be that Map sets up corresponding relation between the position of element units under key word and this key word, when carrying out retrieval, Map is converted to corresponding stored position information by hash algorithm with key word, directly find the elements corresponding unit by this positional information again, and from the element units that is found, extract element value.Therefore, Map is the data capsule with quick locating function.
Search performance fast for what utilize Map, use the system of database multi-list in this step predetermined each time table to be read, and in internal memory, be respectively each time table and set up corresponding Map, the inferior table information of reading in preservation.In the Map that is set up, an element units is corresponding with the list item in time table, the delegation that is about in time table saves as element units among the Map, and each element units is all to be key word, to be element value with the sundry item in this row with the corresponding project of master meter unknown message in this row.With table 2 is example, uses the system of database multi-list at first to obtain SNMP corresponding to Simple Network Management Protocol and the MML information corresponding to the man-machine language interaction protocol from table 2; Then, in internal memory, set up the Map that comprises two element units, the key word of one of them element units is that SNMP, corresponding element value are Simple Network Management Protocol, and the key word of another element units is that MML, corresponding element value are the man-machine language interaction protocol.
In addition, this step also can be read in unknown message and time incidence relation of table in the master meter, so that determine the pairing Map of unknown message when reading time table information.Also can adopt additive method to set up unknown message and time incidence relation of table in this step, for example: set up unknown message and comprise corresponding relation between the Map of this unknown message, and set up the corresponding relation between the unknown message position of element units in Map corresponding with this unknown message.
In this step, the system that uses database is by carrying out a database read extract operation to master meter, obtains all information of preserving in the master meter, and with each row in the master meter as a record, in internal memory, form the master meter record set.
Use the system of database multi-list to be index with the unknown message in the master meter record set in this step, corresponding Map retrieves to inferior table, and after finding the implication of unknown message, Given information in the master meter is combined with the implication of the unknown message that obtains from Map, form complete record.Particularly, the method for this step assembly unit complete documentation comprises:
A. obtain first record in the master meter record set;
B. with the unknown message in the current record as key word, according to unknown message of setting up in advance and the corresponding relation between Map, all Map in the internal memory are retrieved, determine to comprise the Map of this key word, again according to the positional information that obtains by this key conversion, in determined Map, obtain corresponding element value, thereby obtain the information of this unknown message correspondence;
C. the information of the unknown message correspondence that gets access to is combined with Given information in the current record, form a complete record;
D. judge whether current record is the tail record of master meter record set, if, then finish the flow process of this assembly unit complete documentation, and enter step 204, otherwise, turn to next the bar record in the master meter record set, and return execution in step b.
The database multi-list of forming with table 1 and table 2 is an example, in this step at first the SNMP with first record in the formed master meter record set of table 1 be key word, determine the pairing Map of table 2, then in this Map, find the Simple Network Management Protocol of SNMP correspondence, and Simple Network Management Protocol is updated to first record of master meter record set, form the complete documentation that thes contents are as follows: device name Dev1, version V100, use agreement are Simple Network Management Protocol; Turn to the 2nd record of master meter record set then, carry out the assembly unit of complete documentation; The rest may be inferred, till the unknown message MML of the 8th record is replaced, forms complete record by the man-machine language interaction protocol among the Map of table 2 correspondence in the master meter record set.
Because required master meter information and time table information of database multi-list information initializing this moment all is present among the internal memory, so all operations of this step is all finished in internal memory.
In this step, the system of use database multi-list sets up step 201 in internal memory all Map deletions are so that the releasing memory space.
So far, database multi-list information initializing of the present invention is finished.
In the process of database multi-list information initializing of the present invention, comprise table in the multilist of tentation data storehouse n time, and the line number of master meter is m.By above-mentioned step 201 to step 204 as seen, the present invention only needs master meter and each time table are carried out a database read extract operation respectively, be and finish the database multi-list information initializing and need the number of times of reading database to be: (1+n) inferior, (1+mn) that obviously is less than existing database multilist initial method is inferior.
In addition, suppose to read the time that master meter consumes from database is k at every turn
1Second, read the inferior time of showing to be consumed from database is k at every turn
2Second, read the time that Map consumes from internal memory is k at every turn
3Second, owing to whenever read a master meter record, all Map to be read once again, the time of then finishing the database multi-list information initializing is: (k
1+ nk
2+ mk
3) second.Facts have proved, from the Map that is stored in internal memory, obtain a time k that data are required
3Less than ten thousand/second, therefore the database multi-list information initializing time of the present invention is much smaller than (the k of prior art
1+ mnk
2) second.
For the database multi-list of table 1 and table 2 formation, have 8 row, i.e. m=8 in the master meter; Inferior table has only one, i.e. n=1 then finishes the database multi-list information initializing and needs the number of times of reading database to be:
(1+n)=(1+1)=2 time.
The time that suppose to read table 1 again needs at every turn is 0.05 second, and the time of at every turn reading table 2 is 0.02 second, and the time of at every turn reading Map is 0.0001 second, and then the time of database multi-list information initializing is:
(k
1+ nk
2+ mk
3Second)=(0.05 * 1+1 * 0.02+8 * 0.0001)=0.0708.
As seen, when table 1 and table 2 used method of the present invention to carry out initialization, the required time was 1/3rd of prior art.
Under normal conditions, master meter comprises about 100,000 row.Suppose master meter line number m=10
5OK, inferior table number n=3, master meter time for reading k
1=0.2 second, inferior table time for reading k
2=0.05 second, Map time for reading k
3=0.0001 second, when then using the method for prior art to carry out the database multi-list initialization, the time that is consumed was:
k
1+ mnk
2=0.2+10
5* 3 * 0.05=15000.2 second;
And when using method of the present invention to carry out the database multi-list initialization, the time that is consumed is:
k
1+ nk
2+ mk
3=0.2+3 * 0.05+10
5* 0.0001=10.35 second.
As seen, the initialization efficient of initialization efficiency ratio prior art of the present invention has improved more than 1,000 times at this moment.
No matter is the number of times of reading database this moment when using method of the present invention that database multi-list is carried out initialization, or the time that initialization consumed, and all can significantly reduce, thereby make the initialization efficient of database multi-list improve significantly
In a word, use the present invention, can effectively reduce reading database in the database multi-list information initializing number of times, shorten initialization time, improve initialization efficient.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being made, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
