NEW QUESTION # 64
A customer needs to have a calculation done prior to aggregating the data. How would you accomplish this?
- A. By creating a derived measure by using the Logical Columns available
- B. By creating a derived metric by using the Calculation Wizard
- C. By creating a derived measure by using Logic Columns available and changing the aggregation type
- D. By creating a derived metric by using the Expression Builder
- E. By creating a derived measure in the Column Mapping dialog box by using the physical table columns.
Answer: E
Explanation:
Explanation/Reference:
Note 1: OBIEE offers two calculation types for measure in the repository:
logical
physical
You can define calculations in either of the following ways:
* Before the aggregation, in the logical table source.
* After the aggregation, in a logical column derived from two other logical columns. For example: sum(col A) * sum(col B)
Note 2: A measure column is a column unlike the baseline column that has a default aggregation rule defined in the Aggregation tab of the Logical Column dialog in the repository.
Measure columns always calculate the aggregation with which they are defined.
Measures need to be defined in a logical fact. Any column with an aggregation rule is a measure.

NEW QUESTION # 66
Which option describes how OBIEE Integrates with Planning?
- A. OBIEE provides complete access to all Planning data through the Analytic Data Model (ADM) layer.
- B. Planning is not a supported OBIEE source.
- C. OBIEE primarily accesses Planning using standard Essbase integration techniques.
- D. OBIEE integrates with Planning directly through relational database access.
Answer: A,C
Explanation:
Explanation/Reference:
A:
* Combining Relational and OLAP Data Sources: Oracle's Common Enterprise Information Model allows users to combine data from a relational system and an OLAP source in a single calculation. For example, a user can compare sales forecasts from an Oracle CRM System with budget data from an Oracle Essbase planning application. To clients of the Common Enterprise Information Model, the forecast and budget data appear to be from the same logical source.
* The Essbase server provides advanced multi-user read and write capabilities, including data update and multi-user recalculation. Business users with front-end tools can write data back to a server and recalculate the data on a server using calculation scripts-key functionality to support sophisticated modeling and planning applications.
* Using aggregate storage, Essbase serves a wide range of analytic needs-financial analysis, planning, budgeting, sales analysis, marketing analysis, supply-chain analysis, and profitability analytics-all from a single analytic infrastructure.
B:
Note: The Analytic Data Model (ADM) is an API used to access OLAP data and metadata. ADM is similar to JDBC, providing a single common API that hides most differences between OLAP data sources.
Note 2: Data model for business intelligence
The most important component of business intelligence is the concept of 'data model'. data model determinde what kind of analysis that end user could do with the data. It is also an independant concept that could span across different vendor 's product.
Unlike data model of the transaction system, the typical analytic data model is often denormalized and store extra data for analytic query and better query performance while transaction data model use is often normalized and optimized for a few data read and write, which is implemented by jointing many tables.
The most common used analytic data model in business intelligence is call the 'Star schema' data model.
With the Oracle business intelligence system, We could define star schema and dimension data model in the
'logical layer' in the admin tools. The data model in OBIEE could span different data source in physical layer, which means OBIEE have the capability of building one logical data model which is actually connect to different database in the backend
NEW QUESTION # 67
Identify the correct mode to use when opening the web catalog while performing security settings modifications and migrations.
- A. Managed
- B. UnManaged
- C. Offline
- D. Online
Answer: D
Explanation:
In online mode, you connect to a catalog on a running web server. In this mode your permissions are applied, you can select a locale, and you can see the effects of any localization on the catalog. You can see only those objects for which you have the appropriate permissions. Both Presentation Services and the web server must be running for you to open catalogs in online mode.
Use online mode when you want to make minor incremental changes or additions to the catalog, such as changes to permissions, updates to a single object, or migration of new objects to a production environment.
Note:
* You can open a catalog in one of two modes - online or offline. Both modes can operate against an actual production catalog, with no need for any downtime.
* Repository changes can be done in either online
or offline mode. Online mode is when BI Server
is actively reading the repository file (when a
user is logged in). Offline is when BI Server is
idle. Best practice is to develop in Offline mode.
Minor changes can be made when in online
mode.

NEW QUESTION # 69
The ODBC DSN is never used for _______.
- A. Comparing RPDs
- B. Query execution and data access on a Windows server
- C. Changing passwords
- D. Initial import of the physical layer metadata, query execution, and data access on a Windows Server
- E. Initial import of the physical layer metadata on a Windows server
Answer: A
Explanation:
Explanation/Reference:
You do not use ODBC DSN to compare repositories.
Note: When an ODBC based application connects to a database, it connects to a logical name, the Data Source Name (DSN), which identifies the datasource to which it wants to connect.
Some external repository of configuration information holds the various DSN values that are available, together with the necessary configuration and control information needed by the ODBC driver to establish a connection and manage usage of the data source.
The DSN (data source name) is a data structure that contains the information about a specific data source (database, ...), typically used by an ODBC driver to be able to connect to it.
The DSN contains information about the data source such as:
the name,
the directory,
and the driver.
On Windows, the DSN also specifies the ODBC driver to be used to access the database.

* A core rendering engine (Java library) named SDOVIS that performs cartographic rendering. A servlet is provided to expose the rendering functions to Web applications.
* A suite of application programming interfaces (APIs) that allow programmable access to MapViewer features. These APIs include XML, Java, PL/SQL, and an AJAX-based JavaScript API.
* A graphical Map builder tool that enables you to create map symbols, define spatial data rendering rules, and create and edit MapViewer objects.
* Oracle Map, which includes map cache and FOI (feature of interest) servers that facilitate the development of interactive geospatial Web applications.
Oracle Maps can be configured now in the map viewer as a built in layer.
NEW QUESTION # 71
An organization has re-implemented one of its systems but has not moved history. One database has data for all years up to 2010 and the other has data for years from 2011 to the present. The organization needs data from the years 2010 and 2011 on a single report. How can you model this in the RPD?
- A. By creating joins in the physical model so it looks like a single table
- B. By creating two Logical Fact Tables for each database
- C. By creating one logical table sources and checking the "This Source should be combined with other sources at this level" box
- D. By creating two logical table sources and checking the "This Source should be combined with other sources at this level" box leaving the Fragmentation content area blank.
- E. By creating two logical table sources, that specify in Content tab using the Fragmentation content areas to specify the years for each source
Answer: E
Explanation:
Note: This source should be combined with other sources at this level (check box)
Description: Check this box when data sources at the same level of aggregation do not contain
overlapping information. In this situation, all sources must be combined to get a complete picture
of information at this level of aggregation.
Note 2: To use a source correctly, the Analytics Server has to know what each source contains in
terms of the business model. Therefore, you need to define aggregation content for each logical
table source of a fact table. The aggregation content rule defines at what level of granularity the data is stored in this fact table.
Use the Content tab of the Logical Table Source dialog box to define any aggregate table content definitions, fragmented table definitions for the source, and Where clauses (if you want to limit the number of rows returned).
