Step to create a class for external database table

Hi,

Let's say we have an external database table (CONTRACT) which resides outside of Pega platform and we need to connect to it. I have setup a DataSource in JBOSS application server and also created a new DATA-ADMIN-DB-NAME instance using JDBC Connection Pool. It all works fine.

Now, In order to do Obj-Browse to retrieve data from this external CONTRACT table, I believe I need to create a class for it. I want to verify the standard step. First, I have created a concrete class as MyCo-MyApp-Data-CONTRACT. Then I also created a DATA-ADMIN-DB-TABLE instance for this class to point to external database's table (CONTRACT). Test connection is successful. I created a test activity to do Obj-Browse to get data and it is also successfully loaded on to clipboard.

Here are my questions:

#1. Does the class name MyCo-MyApp-Data-"CONTRACT" have to be exactly identical to the external database table (CONTRACT), or is it arbitrary?
#2. Do we need to create the same properties within MyCo-MyApp-Data-CONTRACT as what they have in external CONTRACT table (ex. ContractID, ContractName, ContractDateTime, etc)? It seems I am able to handle data without having any of these properties.
#3. Should we create a physical database table in our local Pega DATA schema? My guess is no, as we are connecting to external database table and we don't need any duplicate table in our side.

Thanks,

Data Integration
