The primary components of the SAP HANA environment are:
In-memory computing engine: This is a component residing within the Index Server. It has got several sub-components such as Planning Engine, Session Management, Disk Storage, Request Processing and Execution Control, Relational Engine, etc.
Database: This has raw data residing in the ERP database which is sent to the HANA database. Replication Agent (in ERP DB) and Replication Server (in the computing engine) provisions this data movement. This component provides log-based data provisioning.
SAP Business Objects BI 4: This component includes tools like SBO BI Information Designer tool, Data Services Designer, Data Services Server, and Data servers, etc.
We use the components for job-based data provisioning. They design and implement a job on data and store the reports created in the form of a result. Therefore, it also acts as a repository.
SAP HANA Studio: This is a user interfacing platform which an Eclipse-based tool where we can manage, administer and manipulate data. We can work on several views like Attribute, Analytic, and Calculation.
Clients: These are miscellaneous reporting tools which we can connect to the computing engine by utilizing specific drivers. We can design and share reports by utilizing these tools and client applications.
Note: This question is very important for your SAP HANA interview. Prepare it nicely.
