Use Case Model: Internal Temporary LOBs

Table 11-1, "Use Case Model Overview: Internal Temporary LOBs", indicates with + where examples are provided for specific use cases and in which programmatic environment (see Chapter 3, "LOB Support in Different Programmatic Environments" for a complete discussion and references to related manuals).

We refer to programmatic environments by means of the following abbreviations:

• P -- PL/SQL using the DBMS_LOB Package

• O -- C using OCI (Oracle Call Interface)

• B -- COBOL using Pro*COBOL precompiler

• C -- C/C++ using Pro*C/C++ precompiler

• V -- Visual Basic using OO4O (Oracle Objects for OLE)

• J -- Java using JDBC (Java Database Connectivity)

• S -- SQL
