can anyone clear me about the hierarchy of the following or which resides where :
1. Sap systems like R/3, SRM, CRM etc.
2. Landscapes
3. Application server
4. Database server
5. Central instance
6. Database instance
7. other instances
Hi dinesh,
I think it is better for you to do an installation on SAP R/3, so that you will come to know where these terms will be used in real scenario.
Application server is the one where your the entire applications are executed.
Database server is the one where the entire data is stored.
Central instance is the one where you have all types of work process such as spool, bacground, enque etc..
Database instance is the instance of the database server where the entire data is stored.

Hi Dinesh,
Firstly differentiate between Database and SAP R/3 application.
Database server will have database, which simply is a data store and database instance which comprises of all the processes that make it operatable. Processes like which make any application to access the information in database.
Now, a SAP solution comprises of instances too which reside on application server, which again is a collection of different processes that make system runnable. Instances in SAP are divided into two parts:
1) Central Instance: which has processes governing all other instances.
2) Application Instance: Can be many, depending upon how many users and their type of work.
All these together make up a landscape for a particular customer.
Award points if usefull.
