About DatabaseIntegrate

DatabaseIntegrate (databaseintegrate.com) is an independent reference for developers who integrate applications with relational databases. It focuses on the parts of that job that most often go wrong in practice: getting the connection right, writing queries that stay fast as data grows, choosing indexes, and keeping data valid.

What is here

• 10 SQL query optimization techniques – starting from EXPLAIN ANALYZE and working through common anti-patterns.
• Database indexing guide – when to add an index, which type, and what over-indexing costs.
• Data integrity and validation – constraints, transactions and application-side checks that keep bad data out.
• Developer tools – a connection string builder for common engines and a data migration planner for mapping fields between systems. Both run in your browser.

Who it is for

Backend and full-stack developers, students learning SQL, and anyone maintaining an application whose database has started to slow it down.
