A very extensive role indeed. 26 Chapter 1: ✓ Introduction to the Oracle Server Technologies TWO-MINUTE DRILL Position the Oracle Product Family ❑ The Oracle database stores and manages access to user data. ❑ The Oracle Application Server runs applications that connect users to the database. ❑ Oracle Enterprise Manager is a tool for managing databases, application servers, and if desired, the entire computing environment. ❑ Languages built into the database for application development are SQL, PL/SQL, and Java.
In the early days of computing, storage devices lacked the capability for maintaining the many separate files that were needed for the many relational tables. Note that this problem is avoided in the Oracle database by abstracting the physical storage (files) from the logical storage (tables); there is no direct connection between tables and files, and certainly not a one-to-one mapping. In effect, many tables can be stored in a very few files. A hierarchical structure stores all related data in one unit.
Procedural languages are usually less efficient than set-oriented languages at managing data, both as regards development and as regards execution. A procedural routine for looping through a group of rows and updating them one by one will involve many lines of code, whereas SQL might do the whole operation with one command: programmer productivity increases. During program execution, procedural code gives the database no options; it must run the code as it has been written. With SQL, the programmer states what he/she wants to do, but not how to do it: the database has the freedom to work out how best to carry out the operation.
