The illustrations of the non-system variable usually comprise of user-defined filters. On the other hand, system variables comprise generally of NQ_SESSION.
Q. Define the process of creating changes for reports, dashboards, and RPD from the development of the product
To carry out these assignments, you can use the merge option in the Admin tool. Moreover, in case of reports and dashboards, one can also use the framework of a content accelerator.
Q. How can you carry out adding the additional column to a tab of a repository in the presentation cover?
If you want to carry out this function, you have to make sure that the table exists or not. If the table exists, then you have to click on BMM and later on the cover of presentation. One can also reload the metadata server so that it would be visible to the interested viewers.
Q. Define the phenomenon of table alias that is present in 11g. Which are the areas and how would you create?
Table alias can be used for facilitating self-joins. Moreover, you can create table alias by right-clicking on the table in the natural cover and then you can click on a nickname.
Q. Illustrate on the process of disabling and enabling caching at the table level and system level
To carry out the enabling function, you can use ENABLE function under the CACHE Section for the System Level Administrator. On the other hand, in case you want to enable cache then you have to make sure that you open the repository tab in the offline mode. It would be different from the current repository, and then you can opt to click on enable or disable functions to facilitate cache.
Q. Define level based metrics and illustrate the process of its creation
Level based metrics usually denotes to hold a certain level of the dimension. For instance, quarterly sales or monthly sales can be dragged into the category of standard based metrics.
