How can I join\relate\connect communities\UMP\BuiltUP\Admin boundaries?

Could you please consider the following scenario:

  1. I have a feature class with a name “community “ which I consider it the main layer in may work, so I relate it to more than one table and it has many information about the community.

    enter image description here

  2. Then I have three other feature classes each one is stored in a deferent file geodatabase ( built-up area, UMP urban master plan, and Administrative boundary).

    enter image description here

Now how could I join\relate\connect the three feature classes (built-up area, UMP, and Administrative boundary) to the (community) feature class so that when I identify the community point I can get the whole results from all feature class?

enter image description here


If i got you,you have common field among tables so better to use Join command and export the result to get a combined feature(composite). This will not add geometry to the composite but only features' attributes only.


N.B.If you are working with lot of data then take different approach, i mean you need to use RDBMS where you will link both table using Primary/Foreign Key.BTW there is a relationship feature class in geodatabase you can use it too.

  • Thanks msi_g, but as you see in the following images I cant know form which layer is the field came !snapshot1 !snapshot2 – Ahmad saleh Jan 28 '15 at 12:11
  • Then add a field in each layer's table that tells about layer(e.g. layer name) then join. – SIslam Jan 28 '15 at 12:16
  • Many thanks msi_g fo your prompt help, I am getting more greedy with this issue, it seems that your first method works will with me but let me ask you How could I relate all layers together so when I identify the build up or the UMPs I can get all the records of other layers dynamically – Ahmad saleh Jan 29 '15 at 7:00
  • I already answered( adding new field e.g. for UMP feature class add a field after Ref field, and name it say UMP the this field will appear in the picture you attached s21.postimg.org/t16ns93lz/Clip_5.jpg after Ref field thus you can track the layers.. – SIslam Jan 29 '15 at 7:08
  • Sorry mis_g I didn't clarify myself, what I wanted to say that is there any way to remain the four layers connected and share the same attributes, for example communities layer is related to many tables, could I relate the UMPs and Builtup layers so they stay connected to the commuinties layer whatever I updated the communities it will be reflected dynamically to other layers – Ahmad saleh Jan 29 '15 at 7:44
