Why Should You Use Visual SQL Tuning Diagrams

SQL queries are the primary mechanism to interact with databases. Therefore, ensuring that SQL queries perform well is essential. An important method to improve the performance of SQL queries is to use indexes properly to locate data quickly. To create useful indexes, it is essential to understand how databases store data versus what type of data SQL queries need to access.

Visual SQL tuning refers to parsing an SQL query, analyzing the indexes and constraints on the tables in the SQL query, and displaying the SQL query represented as relational models in diagrams. Visual SQL tuning helps see flaws in designs of schemas (such as Cartesians joins, implied Cartesians joins, and many-to-many relationships). The visual SQL tuning diagram also helps to understand more quickly the components of an SQL query, thus accelerating troubleshooting and analysis.
