Lab 1. Application Development Flow
This exercise will introduce you to the Objectivity/DB C++ development environment. You will be provided with a simple example to study, build and run. In the process you will be exposed to the essential Objectivity/DB programming interface and tools.
Lab 2. Objectivity/DB Programming
Starting and committing transactions, opening a federated database and a database, creating your own containers and placing objects in them - learn all the basic concepts to get you started with Objectivity/DB Programming.
Lab 3. String Classes
This exercise introduces the Objectivity string class ooVString.
Lab 4. System, Scope and ooMap Names
Assign names to individual objects and containers using Objectivity/DB's various naming mechanisms and use those names for later retrieval.
Lab 5. Associations
Use Objectivity/DB associations to define relationships between objects in your database.. You will declare the association in your DDL files and use the corresponding generated methods in your application.
Lab 6. Iterators
This exercise explores the use of the various Iterator classes in Objectivity/DB. You will iterate by containment, by type (with and without a predicate) and by association.
Lab 7. Indexes
Learn how to speed up your predicate scans. Create an index structure using Key Descriptors and Key Fields, and retrieve them using Predicate Query.
