SAP Data is segregated into three layers
1) SAP standard objects
2) Cross client objects
3) Client specific objects or Data

1) SAP standard objects: These are nothing but repository objects which includes functions, transaction, programs, screens etc………..
• All these are in the name space of A to X
Note: never try to change the repository objects unless and until it is required

2) Cross client objects : These are cross client tables which can be modified            
Ex: currency table, measurement table, client administration table etc…...
• what ever changes we make of type cross client will effect all the users present under that clients

3) Client specific objects (or) Data:  a change which are specific to a particular client is called client specific Data..
Ex: user master Data, application Data, customized Data
