This article mainly introduces "how to establish JSP operation to improve the efficiency of database access". In daily operation, I believe many people have doubts about how to establish JSP operation to improve the efficiency of database access. Xiaobian consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubt of "how to establish JSP operation to improve the efficiency of database access". Next, please follow the editor to study!

Database access through JSP does not require much booting. The problem is how to enable developers to accept that the database access of Web programs is more attractive than that of traditional local OLAP systems, and make them realize that clean and concise data access methods are the key. At this point, JSP can solve it very well.

What can you do?

If you are writing a Web program with high data volume and high data density, what are the requirements for your database access? If you are using JSP, you have to deal with a lot of server-side data. The program may need a lot of data, or a lot of users, or a combination of both. Other possible areas you will consider include performance optimization, detectability, the impact of multiple queries per user, the complexity of queries, and high-level type conversions when a single session processes large amounts of data.

This involves large-scale processing. However, JSP can help you handle it well because it is well compatible with JavaDatabaseConnectivityAPI (JDBC). You can include JDBC in JSP code, and JDBC can pass statements to execute database-like commands, as long as you can use the JDBC driver correctly.

How to establish JSP operation to improve the efficiency of database access

Start

Here is a common, abstract JSP program execution system. The preferred JSP design pattern is Model-View-Controller (MVCModel-View-Controller), which is a variation of the traditional three-tier system in order to be more suitable for server programs. In JSP's MVC design pattern, Model refers to the logic and data of the program, View for viewing, and Controller for request processing.

When you design a JSP program, it is the best process to create the first step of the page between the client and the server. For example, in a typical program, each specific step in a data exchange has a page: a data entry page, a validation request page, a database response page, and child pages of these pages (a page for changing records, a page for deleting records, and so on).

You can embed JDBC into each page to complete the requested database operation. However, this operation is also risky, because the entire program ── JDBC is based on SQL because it mixes JSP and JDBC. This is why SQL is encapsulated in JDBC, and JDBC is encapsulated in JSP ──, which is enough to make you confused. If you choose this method, you will get the functionality you want, but be careful to make sure that the relationship between your program logic and database access code is very clear.

At this point, the study on "how to establish JSP operations to improve the efficiency of database access" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
