Data manipulation

Now the schema has been created in the database, we want to create, update and query Person and Employee instances.

Creating and updating objects

To create and update objects, there are 3 ways: - the OQL language - the C++ binding - the Java binding

Contrary to the schema creation, all these solutions are quite reasonnable.

The first way is the most attractive because one can create and update objects in a very intuitive and interprated way using the eyedboql monitor.

We will introduce in the manual the three solutions.

Querying objects

To query objects, there are only one way: use the OQL language.

But note that the OQL language can be used within the C++ and Java binding in a very well integrated way.
