Aims
Theoretical knowledges about object databases and semistructured data. Implementing one
aplication in Oracle 9i, an object-relational database management system, using XML too.
Content
1.The development of object-database systems in two distinct paths: object-oriented database systems and object-relational database systems.
2. The design of object-database systems, the Object Definition Language (ODL).
3.Query languages for object-database systems
3.1 Declaring methods in ODL.
3.2 Language OQL
3.3 Language SQL3
4. Object-relational programming in Oracle 9i.
4.1 Complex objects (Object Type)
4.2 Select - from - where expresions using methods of objects, attributes of complex
objetcts.
4.3 Application developing using complex objects in Oracle 9i
5. Semistructured data model.
6. XML
6.1 Basic syntax
6.2 XML and semistructured data
6.3 Document Type Definition
6.4 Stylesheets
6.5 The Document Object Model
7. Quering semistructured data
7.1 Un-SQL query language
7.2 XQuery query language
7.3 XSLT

Assessment
Students has two develop one object-relational database application: design the database
using complex objects, implement it in Oracle 8i, using XML features, the interface in a
visual programming language.
