NEW QUESTION # 37
The administration tool is the developer's interface to the repository file. It allows the development of and changes to the metadata repository file. Which statement is true?
Answer: A
Explanation:
Explanation
The Oracle BI repository development process adheres to the classic Software Configuration Management (SCM)process, which utilizes a three-way merge to manage concurrent development.
The merge process involves three repositories:
* The (Original|Received|Master|Parent) repository. The repository that you received before changed. You must keep it preciously unchanged.
* The Modified repository. The repository that contains the customizations you made to the original repository.
* The Current repository. Generally, the repository that is in production and where some customisations could have been performed by other people.
In a multiuser environment (MUDE), Developers check out the file and make changes locally. Then, these changes are automatically reconciled and merged into the master repository.
NEW QUESTION # 38
What are the two leading design solutions recommended by Oracle that you would use for performance?
Answer: A,B
Explanation:
Explanation/Reference:
C: OBIEE Caching and Cache Seeding
Cache is a component that improves performance by transparently storing data such that future requests for the same criteria can be served much faster. Like other application cache is not virtual memory in OBIEE. In OBIEE cache will be stored as files on the Hard Disk of the OBIEE Server in the form of files. By Default caching is enabled in the OBIEE server configuration.
For time-consuming Dashboard Pages, we can use the concept of cache seeding in OBIEE, this can be configured as a scheduled job that will ensure that the data is cached and readily available as and when the user runs the dashboard.
Incorrect answers:
D: Guided navigation is a feature of Oracle BI Interactive Dashboards that enables the content and layout of Oracle BI Interactive Dashboard to change dynamically based on changes in the information being analyzed.
Specifically, sections in a dashboard page can be set up and only appear when there is "interesting" information in the data.
NEW QUESTION # 39
A customer frequently queries multiple dimension tables without a measure. What needs to be defined in the presentation layer?
Answer: D
Explanation:
Explanation/Reference:
You can define calculations in either of the following ways:
- Before the aggregation, in the logical table source. For example:
sum(col_A *( col_B))
- After the aggregation, in a logical column derived from two other logical columns. For example:
sum(col A) * sum(col B)
Incorrect answers:
A: Defining the Logical Key of a Fact Table
Foreign Key Logical Joins
If foreign key logical joins are used, the primary key of a logical fact table should then be comprised of the foreign keys. If the physical table does not have a primary key, the logical key for a fact table needs to be made up of the key columns that join to the attribute tables as follows:
1.Look at the foreign keys for the fact table and find references for all of the dimension tables that join to this fact table.
2.Create the logical key of the fact table as a combination of those foreign keys.
B: You can find this functionality in the general property of a subject area in the repository.
The goal of this definition is to guide the BI Server to make the best choice between two possibles query path.
Multiple path occurs when, if you choose two attributes of dimensions that links together to two fact tables.
For instance, this case can occurs when you create for instance a constraint dashboard prompt.
To guide OBIEE in the best choice, you need to select a fact attribute (measure) as an implicit fact column.
C: What are the benefits of using Aliases in OBIEE?
It is a best practice to create aliases for all tables. Aliases are created in the Physical Layer of the repository. Some of the benefits of using aliases are given below:
You can create a join relationship which is different than the actual foreign key relationship in the database. This helps in defining relationships to meet business model criteria.
An alias is used to avoid circular joins and to configure self joins. (for more details on Fan Trap and Circular Joins check this blog.)
Aliases can function in numerous ways to define business model e.g. a table can act both as a dimension and a fact using aliases.
You can rename aliases to make physical and business model easier to understand.
NEW QUESTION # 40
Pre Deployment sign-off is a milestone for a OBIEE implementation and is based on successful completion of certain tasks. Which option is not one of them?
Answer: C
NEW QUESTION # 41
An organization has its employees' names in an Employees table, and information about their jobs in a Jobs table.
However, an organization's employees can have multiple jobs, and the same job can be performed by multiple employees. This situation would result in a many to-many relationship between the Employees and Jobs tables. How can the many to-many relationship issue be resolved?
Answer: C
Explanation:
Explanation/Reference:
When you need to model many-to-many relationships between dimension tables and fact tables, you can create a bridge table that resides between the fact and the dimension tables. A bridge table stores multiple records corresponding to that dimension. In the Administration Tool, General tab in the Logical Table dialog box contains a check box that you can select to specify that a table is a bridge table.
A bridge table allows you to resolve many-to-many data relationships.
