Table

A table is a tabular data structure for storing data in the relational database system. Unlike data object, which is an "in-memory" data container, the table represents persistent data. It consists of columns and rows. A row represents an instance of the data entity, columns are its attributes. Tables also usually do not exist on their own; they are interconnected using connectors, which define the relationships between the tables.

Modeling of database tables is part of the whole data modeling discipline, which addresses the different levels of data models, relationships between them, and good practices. The data modeling is elaborated more in this chapter.
