Description
Technical field
The present invention relates to database technical fields, more specifically to a kind of method for reading data and device, a kind of number
According to storage method and device.
Background technique
In the prior art, when needing to read desired XML message from database, need technical staff according to data
Library directory is searched one by one, and since database object is numerous, search efficiency is slow, obtains not so as to cause data reading performance using redundancy
To raising.Alternatively, technical staff writes corresponding reading program according to the XML message currently to be read, the program write is utilized
Lookup reading is carried out, and when due to reading data every time, requiring technical staff is that the current data for wanting to read write reading
Program causes development amount to increase to increase the workload of technical staff, reduces reading efficiency.
Correspondingly, when needing to be stored in XML message, it is also desirable to which technical staff writes according to the XML message currently to be stored
Corresponding storage program, this equally also increases the workload of technical staff, development amount is caused to increase, and reduces storage effect
Rate.
Wherein, the expression of relationship and record between XML message support arbitrary data.Such as: in personal reference report XML, meeting
A personally identifiable information is recorded, and is associated with a plurality of credit operation information of this person, can be associated with again under every credit operation information
A plurality of refund records information, and final entry goes out a people and corresponds to multiple credit operation information, this information association gets up to be stored in data
Library, i.e. constituent relation type database.In relevant database, based on tables of data, different numbers are showed by the external key of table
One-to-one, many-one relationship between.Relevant database such as Mysql, Oracle, PostgreSQL, DB2 etc..
Therefore, data-handling efficiency how is improved, development amount is reduced, is that those skilled in the art need what is solved to ask
Topic.
Summary of the invention
The purpose of the present invention is to provide a kind of method for reading data and device, a kind of date storage method and device, with
Data-handling efficiency is improved, development amount is reduced.
To achieve the above object, the embodiment of the invention provides following technical solutions:
A kind of method for reading data, comprising:
The keyword of the XML message to be read of user's input is received, and determines father's label of XML message according to keyword；
Father's label is added to preset aiming field, inquires target data corresponding with aiming field in the database
Table；
The data content of the field item in target matrix is read, XML message is obtained.
Wherein, father's label of XML message is determined according to keyword, comprising:

Wherein, the father's label and aiming field of XML message have been stored in advance in FTL file.
Wherein, XML message is obtained by FTL file, comprising:
FTL file is traversed, according to the transformational relation and data content of father's label and aiming field, generates XML message.
A kind of reading data device, comprising:
Receiving module, the keyword of the XML message to be read for receiving user's input, and XML is determined according to keyword
Father's label of message；
Enquiry module is inquired and aiming field pair in the database for father's label to be added to preset aiming field
The target matrix answered；
Read module obtains XML message for reading the data content of the field item in target matrix.
A kind of date storage method, comprising:
Obtain XML message to be stored；
The label of XML message is extracted, label includes: the subtab of father's label and father's label；
Father's label is determined as to the table name of tables of data, and subtab is determined as to the field item in tables of data；
The data content of subtab is stored into field item, and tables of data is stored in database.
Wherein, the data content of subtab is stored into field item, comprising:
The major key field of the data content of subtab and father's label is stored into field item.
Wherein, the major key field of the data content of subtab and father's label is stored into field item, comprising:
The major key field of the data content of subtab and father's label is stored into field item according to breadth-first algorithm.
Wherein, further includes:
When there are multiple father's labels or multiple subtabs, by marking multiple father's labels or multiple sons respectively from increasing number
Label.
A kind of data storage device, comprising:
Module is obtained, for obtaining XML message to be stored；
Extraction module, for extracting the label of XML message, label includes: the subtab of father's label and father's label；
Subtab for father's label to be determined as to the table name of tables of data, and is determined as the word in tables of data by determining module
Duan Xiang；
Tables of data for storing the data content of subtab into field item, and is stored in database by memory module.
By above scheme it is found that a kind of method for reading data provided in an embodiment of the present invention, comprising: receive user's input
