Which SAP HANA Schema Contains the Runtime Objects of Activated Views?
Question:
Which of the following SAP HANA schemas contains the runtime objects of activated views?- A. _SYS_STATISTICS
- B. _SYS_REPO
- C. _SYS_BI
- D. _SYS_BIC
Understanding SAP HANA Schemas and Runtime Objects
SAP HANA features several predefined system schemas, each serving a specific purpose. Understanding these schemas is crucial for efficiently managing data models and queries in SAP HANA.Among the available schemas, _SYS_BIC (System Built-In Calculation) is the schema that stores the runtime objects of activated views. Let’s explore this in more detail.
What is the _SYS_BIC Schema?
The _SYS_BIC schema in SAP HANA is a read-only schema that automatically stores runtime objects for activated views. These views include:- Calculation Views
- Analytic Views
- Attribute Views
How to Access and Use the _SYS_BIC Schema?
Step-by-Step Guide
To view and analyze objects in the _SYS_BIC schema, follow these steps in SAP HANA Studio:- Open SAP HANA Studio and establish a connection to the system.
- Expand the “Catalog” section in the left-hand panel.
- Locate the _SYS_BIC schema under the system database.
- Browse the available views and open the desired runtime object.
Key Differences Between _SYS_BIC and Other SAP HANA Schemas
| Schema | Purpose |
|---|---|
| _SYS_BIC | Stores runtime objects of activated views (read-only). |
| _SYS_REPO | Stores design-time objects (original development artifacts). |
| _SYS_BI | Stores metadata for Business Intelligence (BI) functions. |
| _SYS_STATISTICS | Stores system performance and monitoring data. |
Important Note: You cannot modify objects inside _SYS_BIC. If changes are needed, they must be made in _SYS_REPO, and the view must be reactivated to update the runtime object in _SYS_BIC.
Conclusion
The _SYS_BIC schema is essential in SAP HANA as it stores the runtime objects of activated views. Since it is a read-only schema, any modifications must be made in the development schema (_SYS_REPO), followed by reactivation.Understanding this distinction helps developers and database
administrators efficiently manage and troubleshoot SAP HANA data models.
