What are the principles and methods for optimizing Oracle?

Principles and methods of Oracle optimization include:

1. Utilize appropriate indexes: Make sure that the columns on database tables have the appropriate indexes to speed up query performance.
2. – Optimize SQL statements: Write efficient SQL statements to avoid full table scans and unnecessary join operations.
3. Utilizing stored procedures and functions to encapsulate complex business logic can reduce network transmission and repetitive code, thereby improving performance.
4. Partitioning tables and indexes: Partitioning large tables can improve the performance of queries and insert operations.
5. Choose the appropriate data type: selecting the right data type can reduce storage space and improve query performance.
6. Regularly collect statistics: By collecting statistics on tables and indexes, the Oracle optimizer can make better choices when selecting an execution plan.
7. Optimize memory and disk configuration: Properly configuring memory and disk can improve the overall performance of the database.
8. Utilizing SQL tuning tools: Oracle offers various tools such as SQL Tuning Advisor and SQL Performance Analyzer to help optimize the performance of SQL statements.

By following the above principles and methods, the performance of Oracle database can be effectively optimized.
