First of all, the database should have a good maintainability, flexibility, and the database of the algorithm logic must also have a certain degree of optimization, so that resources can be eff

Remember, the first time to write a computer room fee system Document template, a full 12 documents need to write, just spent two or three days to let the master acceptance, the completion of the project, so swallowed the document was written.

manipulate mobile devices by using buttons, labels, and so on. On the computer, moving the mouse, clicking the hyperlink is an ideal way to view information, but on the mobile device, it is not easy to open the hyperlink by touching the screen with your finger. Users can easily activate a link to enter a new page, but this is not the user's desired page, and if so, it will result in a very poor experience. Four, the picture in the webpage, we often c

only use a table, and precisely facade class also according to the table, then the number of calls to the facade class will inevitably increase. 3. Application Advantages of abstract Factory + reflection + configuration fileWhen it comes to the factory family, it's hard to think of their fondness for switch statements, but if the number of database tables is too large and requires different database switching, Swtich will inevitably add a lot of meaningless judgments, so that through the Factor

It is not hard to see that communication has an important impact on the performance of distributed memory parallel computers. The compilation of complex message passing statements has become a difficulty in parallel program design on such parallel computers. However, this type
