You are just starting with a new team that has been working together on an application for months. They ask you toreview some of their views thathave been degrading inperformance. The viewsare highly complex with hundreds of lines of SOL What is the first step in troubleshooting the degradation?
Correct Answer: B
Explanation The first step in troubleshooting the degradation of the views is to run an explain statement on the views, identify critical areas of improvement that can be remediated without business knowledge. An explain statement is a tool that shows how a database executes a query or a view, and provides information about the cost, plan, and steps involved in the execution. By running an explain statement on the views, you can identify any inefficiencies or bottlenecks that are causing the degradation, such as missing indices, full table scans, nested loops, or hash joins. You can then apply some basic optimization techniques that do not require business knowledge, such as creating indices, limiting the number of columns or rows returned, using joins instead of subqueries, or using materialized views.
