This article will explain why optimization is so important as we explore some of the best ways to quickly optimize your SQL queries for minimum impact on database performance through:

  • Efficient indexing,
  • SELECT and SELECT DISTINCT statement refinement,
  • Strategic use of wildcards and conditionals, and
  • Query cost analysis using EXPLAIN

Introduction to SQL Query and Data Management

Standard Query Language, or SQL for short, allows users access to databases using specific commands or queries, allowing them to change and maintain them. Commands such as SELECT — which helps users extract the data from the database — UPDATE, DELETE, INSERT INTO, and many more, make data management easier for database administrators.

Each of these commands has its own set of functionalities that are useful when working with databases. A few SQL IDEs, such as Arctype, offer developers the ideal framework for visualizing, designing, modeling, and managing their databases. Arctype is a free, collaborative, and intuitive SQL editor to simplify all your data management and visualization requirements.
