Relational databases store all their data in Tables. A table is a data structure consisting of an unordered set of horizontal rows, each containing the same number of vertical columns. The intersection of an individual row and column is a field that contains a specific piece of information. Much of the power of relational databases comes from defining the relations among the tables.

  • edit table subobjects and data using the appropriate tabs of Table Editor.


Dropping Tables

  • select the table to drop in the DB Explorer tree;
  • right-click the object and select the Drop Table <table_name>... context menu item;
  • confirm dropping in the dialog window.
