Optimizing Your Database and SQL Queries

Databases are a key component of large software systems. These systems constantly retrieve and update data using database connections and queries. The scale of data in modern systems is extremely large, resulting in more data to query, update, and display. This increased scale can result in negative performance issues for our Java application, underscoring the significance of ensuring our databases and queries are optimized.

This chapter examines critical database design concepts, including database schemas, indexing strategies, and data partitioning techniques. Database queries are also examined, with a specific focus on Structured Query Language (SQL) queries. Our coverage of query optimizations includes best practices for writing efficient queries, query execution planning, and advanced SQL techniques.

The chapter also covers advanced SQL techniques such as database configuration, performance monitoring, and database maintenance. The...
