The storage section resource stood is by excessive occupancy.
The size for storing section is dynamic change as needed.X represents storage section increased step-length every time, X roots
Suitable data are taken according to page-size in paging, it generally should not be too big.The storage section of this dynamic size can effectively be protected
It demonstrate,proves to the quick corresponding of client request, and it may ensure that the influence that speed is brought from the increase of total amount of data, is suitble to
The long-run development of application.On the other hand, for the storage section size X in step A value, it is necessary to ensure depositing for X datas
It disclosure satisfy that the demand of in most cases client between storage area, reducing requested database increases the number of storage section size.
When news mark is loaded into storage section, each news can also be identified corresponding article entity and loaded
To another storage section（I.e. second storage section）In, thus after the mark of the news needed for user is inquired, it can be by this
The corresponding article entity of mark is extracted in known article list from another storage section for use, when user chooses some a bit
When news identifies, it is possible to which rapid extraction goes out the corresponding article entity of mark chosen and is presented to use from another storage section
Family since the loading of article entity is in another storage section, avoids the issuable interference in extraction mark and entity.
Corresponding data are being inquired about according to Data Identification（Entity）When, it may be possible to it inquires, it is also possible to inquire about less than right
In the mark that can not inquire about corresponding data, can be stored to unknown article ID lists（That is the presets list）In, Ran Houzai
After having handled all Data Identifications, all Data Identifications that can not inquire corresponding data are just stored in unknown article ID
In list, and then corresponding data are extracted from database further according to the Data Identification in list is unified, avoid cyclic query
Each unknown article ID to extract article entity from database, but disposably looked by a unknown article ID list
It askes database and obtains an article list of entities, improve the efficiency of data query and extraction, reduce the inquiry time of database
Number.
