Overview of Primary Components The Oracle architecture includes a number of primary components, which are discussed further in this lesson. Oracle server: There are several files, processes, and memory structures in an Oracle server; however, not all of them are used when processing a SQL statement. Some are used to improve the performance of the database, to ensure that the database can be recovered in the event of a software or hardware error, or to perform other tasks necessary to maintain the database. The Oracle server consists of an Oracle instance and an Oracle database.

The Verilog HDL supports a hierarchical hardware description structure by allowing modules to be embedded within other modules. Higher level modules create instances of lower level modules and communicate with them through input, output, and bidirectional ports. These module input/output (I/O) ports can be scalar or vector.
