Oracle 1z0-591 Exam With Confidence Using Practice Dumps

Oracle Essbase developers creating planning and budgeting applications have been keenly aware of the advantages and disadvantages of the two different storage types available to them:

* Block storage option (BSO) databases support a wide range of calculations, including forecasts, allocations, and aggregations through procedural calculation scripts. The results of these calculations can be written back to the database, but applications that use BSO storage are limited to about 10 dimensions and member counts in the low hundreds of thousands.

* Aggregate storage option (ASO) databases can support about 20 dimensions and member counts in the millions. ASO databases use multidimensional functions rather than procedural scripts to perform calculations, but the results of queries cannot be stored back in the database, making ASO unsuitable for most financial management applications.

Object-level security controls the visibility to business logical objects based on a user's role. You can set up object-level security for metadata repository objects, such as subject areas and presentation folders, and for Web objects, such as dashboards and dashboard pages, which are defined in the Presentation Catalog.

1) Business logic object

This controls access to objects, such as:

* subject areas

* presentation tables

* presentation columns

For example, users in a particular department can view only the subject areas that belong to their department.

2) Web object security

This provides security for objects stored in the Web Catalog, such as dashboards, dashboard pages, folders, and reports. You can view only the objects for which you are authorized. For example, a mid-level manager may not be granted access to a dashboard containing summary information for an entire department.
