SQLHelper is a wrapper around DbConnection/DbCommand and a micro ORM. It automatically handles batching, data conversion, transactions, etc. for you. It's been around even longer than Dapper as part various libraries I've had over the years.
Storm is a modern, high-performance ORM for Kotlin 2.0+ and Java 21+, built around a powerful SQL template engine. It focuses on simplicity, type safety, and predictable performance through immutable models and compile-time metadata.
A library to help with analyzing a database. It then make suggestions for improvement or can apply them automatically if you like to live dangerously. For the most part it reports recent expensive queries, missing indexes, overlapping indexes, and unused indexes. However it can be expanded upon to add your own analyzer.
An ORM. Useful for prototyping but it has the ability to generate a database from a model, keeps them in sync, and has the ability to analyze the database and make suggestions. Has lazy loading, allows quering using IQueryables, straight SQL, and caching of data is built in. So in otherwords, it's a basic ORM.
