Technical Questions

• 6. What is the difference between a logical table and a physical table in OBIEE?
  A logical table is a virtual table created in the Business Model and Mapping layer to represent the underlying data source. A physical table is a physical data store in the Data Source layer. In other words, physical tables are the actual tables in the database, while logical tables are derived from them to define the business model.
• 7. Can you explain the process of creating reports in OBIEE?
  In OBIEE, reports are created using the Answers feature. The process involves creating a request, adding appropriate columns and filters, and selecting the desired visualization format. The result is a report that can be further customized with advanced formatting, conditional formatting, and interactive features.
• 8. What is the purpose of a repository in OBIEE?
  The repository is a metadata layer that stores all the information about your data sources, logical tables, joins, calculations, and security settings. It acts as a bridge between the physical data sources and presentation layer and is used to create reports and dashboards.
• 9. How do you optimize query performance in OBIEE?
  Query optimization in OBIEE involves techniques such as aggregating data, using SQL hints, caching, and tuning SQL queries. Additionally, organizing and partitioning data, adding indexes, and optimizing the physical architecture also contribute to improved query performance.
• 10. What steps do you follow when troubleshooting an issue in OBIEE?
  When troubleshooting an issue in OBIEE, I first try to replicate the problem and analyze the steps leading up to it. Then, I use appropriate tools and techniques such as log files, SQL queries, or debugging to identify the root cause. I also consult documentation and collaborate with team members to find a solution.
