You will need a field that exists in both the input features class a in the tables you want to join. Assuming you have that you can:
- right click on the featureclass in the TOC, select Joins and Related, Join...
In the dialog that follows:
- Select the field (1) in the featureclass you want to use for the join, select table (2) you want to join to join featureclass and select (3) the field in the table you want to use for the join
Click OK.
Repeat this process for all the tables you want to join.
If you observed the properties of the feature layer you will see that there are multiple joins.
Next use the export option to make the joins permanent:
- right click on the feature class in the TOC
- Select Data, Export data
- Specify the output location and name and click OK
- A new feature class will be created with the tables joined to it.
If you just want to retrieve the related information and not create a permanent output, you can consider using a relate instead.
