Sample processing of an analysis


When business users log in to Presentation Services and execute one of the analyses, some processing steps are executed in the background. We’re going to cover these steps in this recipe.

Processing steps

  1. Web client runs the analysis to display the result set.

  2. Presentation Services builds the logical SQL statement and forwards this statement to the BI server.

  3. The BI server converts the statement to a physical SQL statement and executes it on the database.

  4. The database server generates the result set and sends it to the BI server.

  5. The BI server forwards the result set to Presentation Services.

  6. Presentation Services displays the formatted result set so the web client accesses the report result.

If the caching option of the BI server is enabled, then the result set is going to be stored in the cache. In the next execution of the analysis, the query will be satisfied from the cache instead of executing the physical SQL statement on the database.

The caching option is controlled in the Fusion Middleware Control window, as displayed in the following screenshot:
