What are the solutions for database performance optimization? This problem may be often seen in our daily study or work. I hope you can gain a lot from this question. The following is the reference content that the editor brings to you, let's take a look at it!

Relational database is widely used in Internet projects. Today, the editor will share with you several database optimization solutions:

1. Adjust the design of data structure. This part is completed before the development of the information system, programmers need to consider whether to use the partitioning function of ORACLE database, whether the frequently accessed database tables need to be indexed, and so on.

2. Adjust the structural design of the application. This part is also completed before the development of the information system, programmers need to consider what kind of architecture the application uses, whether to use the traditional Client/Server two-tier architecture or the Browser/Web/Database three-tier architecture. Different application architectures require different database resources. (recommended study: MySQL video tutorial)

3. Optimize the database SQL statement. Database SQL statement. The execution of the application program ultimately boils down to the execution of SQL statements in the database, so the execution efficiency of SQL statements ultimately determines the performance of the ORACLE database. ORACLE recommends the use of Oracle statement optimizer (Oracle Optimizer) and row lock manager (row-level manager) to adjust and optimize SQL statements.

4. Adjust the server memory allocation. Memory allocation is optimized during the operation of the information system, and the database administrator can adjust the size of the data buffer, log buffer and shared pool of the database system global area (SGA area) according to the database health status, and can also adjust the size of the program global area (PGA area). It should be noted that the SGA area is not the bigger the better. The SGA area will occupy the memory used by the operating system and cause the page exchange of virtual memory, which will reduce the system.

5. Adjust the hard disk Istroke O, this step is completed before the information system development. The database administrator can put the data files that make up the same tablespace on different hard disks to achieve Icano load balance between the hard disks.

6. Adjust the operating system parameters, such as the ORACLE database running on the UNIX operating system, you can adjust the size of the UNIX data buffer pool, the amount of memory each process can use and other parameters.

Database (Database) is a warehouse that organizes, stores and manages data according to data structure. It came into being more than 60 years ago. With the development of information technology and market, especially after the 1990s, data management is no longer just storing and managing data, but has been transformed into a variety of data management methods needed by users.

There are many types of databases, from the simplest tables that store all kinds of data to large database systems that can store massive data.

In the information society, the full and effective management and utilization of all kinds of information resources is the prerequisite for scientific research and decision management. Database technology is the core part of all kinds of information systems, such as management information system, office automation system, decision support system and so on. it is an important technical means for scientific research and decision management.

In the daily work of economic management, it is often necessary to put some related data into such a "warehouse" and deal with it accordingly according to the needs of management.

For example:

The personnel department of an enterprise or institution often stores the basic information of its employees (job number, name, age, gender, place of origin, salary, resume, etc.) in a table, which can be regarded as a database. With this "data warehouse", we can inquire about the basic situation of a certain employee at any time as needed, and we can also inquire about the number of employees whose wages are within a certain range, and so on. If all these tasks can be carried out automatically on the computer, then our personnel management can reach a very high level. In addition, a large number of such "databases" need to be established in financial management, warehouse management and production management, so that computers can be used to realize the automatic management of finance, warehouse and production.
