Informatica 地图创建

问题描述 投票：0回答：2

我需要创建一个可以对数据进行排序和排名的 Informatica 映射。两个不同的应用程序中有两个表，因此我无法直接在 SQL 中连接它们。两者都有大量数据，因此也需要照顾性能。 Senario 可能像下面这样-

有两张表Department(DEPT)和Employee(EMP)。它们有1(DEPT):M(EMP)关系。部门表有列 (Row_id, DeptNm, Created_date)，员工表有列 (Row_id, EMPName, Emp_num, Par_row_id (FK to DEPT.row_Id),Salary)

对于特定部门，按照员工工资递减的顺序对数据进行排序并排序。数据应位于文本文件中，如下所示 -

部门名称|员工名称|薪资|职级
金融|维克拉姆|200000|1
金融|Uttaam|150000|2
金融|Rajeev|100000|3
ITDPPT|巴拉吉|150000|1
IT部门|Harsha|120000|2
ITDEPT|Weeniji|100000|3

提前致谢:)

您可以使用连接器转换来连接部门和员工表。然后使用排序器和排名转换对行进行排名。
