Overview of database operation

From the user’s perspective, a database is a set of data. Data in a database is stored
in tables. Relational tables are defined by their columns and are given a name. Data
is stored in rows in the table. Tables can be related to each other, and the database
can be used to enforce these relationships. Data can thus be stored in relational
format or as object-oriented structures such as abstract data types and methods.
Objects can be related to other objects, and objects can contain other objects. A
database is usually managed by the server (manager) process that maintains data
integrity and consistency.

Whether you use relational structures or object-oriented structures, databases store
data in files. Internally, these are database structures that provide a logical mapping
of data to files, allowing different types of data to be stored separately. These logical
divisions are called tablespaces in Oracle, dbspaces in Informix Server, and segments
in Sybase.
