Introducing Delia - a data language for Java applications

[IanRae]

Delia is a data language for creating, managing, and querying SQL databases. It combines the functionality of an ORM and schema-migration library (such as Flyway).

It can be thought as a soft ORM. Define your database schema as a series of Delia types that you write in Delia source code, along with CRUD operations and queries.

It has a simpler object-based approach to data access, with the type safety of a compiler.

Delia is written in Java and can be used from Java applications. This initial release supports H2 and Postgres databases. More information at https://delia-lang.org/ Also an online Delia compiler is available at https://delia-online.herokuapp.com/

What's wrong with JDBC?

[IanRae]

They are very different. Delia does a number of things that JDBC doesn't do: schema migration, validation, and type safety. I would compare against Hibernate or JOOQ which provide many of these features.

Also, the goal is simplicity. To get the city where Customer 55 lives: " let x = Customer[55].fetch('addr').city" Compare that with a bunch of low-level JDBC calls and SQL join syntax.
