2.1 Types of tables
HADB manages data using tables.
As in other relational databases, tables in HADB consist of rows and columns. The horizontal and vertical directions of a table are referred to as rows and columns, respectively. The data in a particular column is always in the same format for all rows.
Each row consists of one or more columns. A row is the basic unit used for performing operations on a table.
Tables can be classified into base tables and viewed tables. The following subsections explain these in detail.
