14 skills for high-performance Java persistence, high-performance java A high-performance data access layer requires a lot of knowledge about the database, JDBC, JPA, and Hibernate. This article summarizes some important technologies that can be used to optimize enterprise applications. 1. SQL statement log If you use a framework to generate statements that meet

performance, and we can analyze it through the statement log of the database service. Many o/rm can automatically generate table schema (automatically generate tables) based on mapping instructions, but we should not do so, especially in production environments or products, remember that we should design our own tables. If the table design is poor, it is your fault, not o/rm. Java Persistence
