Forinformation on the sample schemas, see Oracle Database SampleSchemas.8.1 Overview of Packages and SubprogramsOracle offers the capability to store programs in the database. This functionalityenables commonly required code to be written and tested once and then accessed byany application that requires the code. Database-resident program units also ensurethat the same processing is applied to the data when the code is invoked, making thedevelopment of applications easier and providing consistency between developers.You can write database-resident programs in PL/SQL and manage source types suchas PL/SQL packages, procedures, functions, and triggers. The actions include creating,compiling, creating synonyms for, granting privileges on, and showing dependenciesfor these source types.Subprograms and Packages: Usage Information describes the main types of PL/SQLprogram units: packages, package bodies, and subprograms.You can use PL/SQL to develop packages and stored (standalone) subprograms. Bothpackages and stored subprograms are saved and stored in the database and can beused as building blocks for applications.Subprograms and Packages: Usage Information 8-1
