Q4. How Can the Presentation Layers Be Migrated to Different Servers?
Answer: The layer of the presentation depends on the base of the server. The layer of presentation alone cannot, therefore, be migrated as an autonomous aspect of the database. Instead, an ODBC or similar base connection from the servers to the particular central system is established, and the display semantics from the other server is carried out by changing the logic layer of that database

In order to organize your content in the most logical way, users can add subfolders to their personal folders.
Q8. Explain the Purpose of Alias Tables?
Answer: A table of an alias is a table of the physical kind of alias. It references a physical table and contains its column definitions and some physical table properties. A table source logic shows the mapping of logical objects to the physical layer and the mapping to physical tables, saved procedures, and select statements. An alias table can refer to any of these logical sources in the table. An important part of designing a physical layer can be Alias Tables.
Q9. Explain the difference between repo variables and session variables?
Answer: Session variables are similar to dynamic repository variables because they obtain their values in the initialization block. However, session variables do not initialize themselves, unlike dynamic repository variables. When a user starts a session, the Oracle BI Server creates and initializes new instances of session variables. A single value is available at any time for a repository variable. The Expression Builder in the Administration Tool allows you to use repository variables instead of literals or constants. The Oracle BI Server replaces the repository variable value for the metadata variable itself.
Q10. What Is a Surrogate Key?
Answer: An artificially produced key, usually a number, is a substitute key. A replacement key, which simplifies this connection in the aggregate table at the level, removes the unnecessary columns from the fact table, thus creating a smaller fact table.
