The Ada Database Objects is an Object Relational Mapping for the Ada05 programming language. It allows to map database objects into Ada records and access database content easily. The library supports PostgreSQL, MySQL, SQLite as databases. Most of the concepts developed for ADO come from the Java Hibernate ORM.
The ORM uses either an XML mapping file, a YAML file or an UML model, a code generator and a runtime library for the implementation. It provides a database driver for PostgreSQL, MySQL and SQLite. The ORM helps your application by providing a mapping of your database tables directly in the target programming language: Ada05 in our case. The development process is the following:
- You design your database model either using a UML tool or by writing an XML or YAML description file,
- You generate the Ada05 mapping files by using the Dynamo code generator,
- You generate the SQL database tables by using the same tool,
- You write your application on top of the generated code that gives you direct and simplified access to your database.
This document describes how to build the library and how you can use the different features to simplify and help you access databases from your Ada application.
