Embodiment
Below in conjunction with Figure of description, the present invention is described in detail, and provide concrete form of implementation.
For the operation of memory database, data base administration process and application program all are client modes, and memory database cooperates the related HASH table of internal memory to can be considered the server end pattern; For the operation of document data bank, adopt the C/S framework to carry out, wherein application program is a client, and the data base administration process is a server end, and application program does not need to understand document data bank and mode of operation thereof.Data base administration C/S framework as shown in Figure 1.
As shown in Figure 2, the XML allocation list has comprised data items table and initialization SQL statement table; Data items comprises data item name and data item attribute, and data item attribute comprises data type, measurement point type and tables of data type; Initialization SQL statement table comprises memory bank initialization statement table and library initialization statement table.
By the analyzing XML allocation list, can create the related HASH table of internal memory of the memory database, document data bank and data of description project and the database relation that are complementary with data items XML allocation list.The related HAHS table with internal memory of memory database all is present among the internal memory, can directly visit by the corresponding interface, and document data bank exists with the database file pattern, must conduct interviews by the data base administration process.The related HASH table of internal memory can be that key word is retrieved with data item, measurement point, table name, as shown in Figure 3.
The data base administration process is according to measurement point parameter, the related HASH table of internal memory, be responsible in memory database, creating the tables of data entity of each measurement point, and from the data table related of document data bank, extract the historical data project, import measurement point internal storage data table, remove each data item " dirty " sign, insert validity flag.The data base administration process is responsible for the operational order formation of initialization files database, creates the exclusive semaphore of document data bank operational order formation, creates the exclusive semaphore of memory database.As shown in Figure 5.
After measurement point parameter modification message trigger, the data base administration service processes dynamically increases, revises, deletes the measurement point tables of data entity in the memory database newly.As shown in Figure 6.
Application process can be by the exclusive semaphore of application memory database, after obtaining the operation power of memory database, according to measurement point parameter, the related HASH table of internal memory each data item of measurement point internal storage data table entity is carried out direct control, operation can influence data item " dirty " sign and validity flag.As shown in Figure 4.
Application process can be by the exclusive semaphore of application documents database manipulation command queue, after the operation power of acquisition document data bank operational order formation, the write data content is write write operation command queue; The data base administration service processes by the write order message trigger after, according to the related HASH table of measurement point parameter, internal memory data content is read and is converted to that SQL writes, the replacement operation statement, write document data bank.Application process can be by the exclusive semaphore of application documents database manipulation command queue, the exclusive semaphore of memory database, after the operation power of acquisition document data bank operational order formation and the operation power of memory database, create interim interaction data table in the memory database application, the read data content is write read operation command queue; The data base administration service processes by the read command message trigger after, according to the related HASH table of measurement point parameter, internal memory the SQL query action statement is read and be converted to data content, the SQL statement Query Result is inserted interim interaction data table after conversion; Application process is obtained the read operation result by detecting interim interaction data table, the interim interaction data table of deletion after operation success or the operation overtime.As Fig. 4 and shown in Figure 8.
After being timed the message trigger of freezing task, the data base administration service processes is by the exclusive semaphore of application documents database manipulation command queue, the exclusive semaphore of memory database, after the operation power of acquisition document data bank operational order formation and the operation power of memory database, detect each data item " dirty " sign and the validity flag of measurement point internal storage data table, to meet the data item that imposes a condition is that timestamp is prestored into document data bank with the timed task triggered time, and whether detection exists the data item of identical time stamp, if exist then do not write, otherwise write freezing data and " dirty " sign that clears data, thereby the history benefit that realizes the measure dot number certificate is frozen.As shown in Figure 7.
After terminal dead electricity message trigger, the moving exclusive semaphore of document data bank operational order formation and the exclusive semaphore of memory database seized of data base administration service processes, internal storage data base content is imported document data bank to be preserved, closing database service also enters dormant state, until terminal again.As shown in Figure 9.
The present invention also can have other various embodiments, without departing from the spirit and substance of the case in the method for the present invention, according to various changes or the distortion that the inventive method is made, all belongs to the claim protection domain of the inventive method.
