RE: Bridge Table |
A table which maintained to define the relationship between two different tables is known as bridge tables. For example, say there are two tables one table with employee information (an employee table), and other with deparment details. Now a bridge table coming to picture to maintain the relationship between an employee with his/her department. which contains informations like which employee belongs to which department.
Here is a example to understand More precisely,
Employee table -------------------- EMP_CD EMP_name DOJ 1001 MR.X 12-06-2006 1002 Ms.Y 24-11-2004 1003 MS.K 25-02-2004
Department table ----------------------- DEPT_CD DEPT_NAME SECTOR_CD MANAGER_NM IT_DEV S/W Developer SDV MR.XL MNGNT HR Management HRD MS.DS
