1z0-591 Exam Dumps - Oracle Business Intelligence Foundation Suite 11g Essentials

You can nest presentation folders in two ways.

1) You can enter a hyphen and a greater than sign in the description field of the table to achieve the result.

2) Or, prefix the name of the presentation folder to be nested with a hyphen and a space and place it after the folder in which it nests to achieve the same result as shown below.

Result

If you want to create a dynamic time-series reference such as the value of a measure as at this time last year, or over the past three months, or year-to-date, you can use one of the OBIEE time-series functions (AGO, PERIODROLLING, TODATE) to provide an offset value for a measure.

Note: OBIEE 11g offered a bunch of improvements that were particularly aimed at Essbase, and other OLAP server, customers; the new hierarchical columns feature brought proper OLAP analysis to OBIEE, and coupled with OLAP-oriented features such as hierarchical prompts and selection steps, made OBIEE 11g a much more conducive environment for Essbase users.

There’s much better support for Essbase-native features such as value-based hierarchies, alternate hierarchies, multiple alias tables, UDAs and other Essbase artifacts, and the value-based hierarchy feature in particular is very welcome as it can avoid the need to completely re-import your Essbase database if your outline gains additional hierarchy levels.

So coupled with the new and improved visualization capabilities in OBIEE 11g, including maps, scorecards, improved dashboard controls, the whole new UI, improved BI Publisher and so on, there’s a lot to recommend OBIEE 11g to users of the “legacy” Hyperion tools looking for a bit of a refresh of their BI environment.

Pull the table and column definition into the physical layer

Use the OBIEE “import metadata” wizard to pull the table and column definition into

the physical layer. The wizard is used so that all of the column definitions do not need to

be manually added into the physical layer.

Figure:

Note: The physical layer is the layer of the Logical Business Model where you define the physical data model of your data source. It contains information about the physical data sources.

The “Edit Column Formula” dialog box has a second,

very tiny tab called, “Bins.” You can use this tab to have OBIEE

build a CASE statement for you in a formula (you can also create

a CASE statement yourself by using one of the functions that

appears under “Expressions” if you want). A CASE statement is a

lot like an IF-THEN-ELSE statement, except that it’s a little easier

to read when you have multiple options. Basically, it puts values

in different buckets that you define.

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.

Oracle Business Intelligence Enterprise Edition (OBIEE) Security is managed through:

a) BI Server Security Manager accessed through the BI Server Administration Tool.

* Set permission to business model, tables, columns and subject areas

* Specify filters to limit data accessible by users

* Set authentication options

b) BI Presentation administration accessed through Presentation Web Services.

* Manage Web groups and users

* Set Permissions for Web Catalog items

* Manage privileges and rights given to groups and users

* Control access to dashboards

c) Catalog Manager.

* Set permission for Web Catalog items (Dashboards and Dashboards pages)

Modeling Time Series Function in OBIEE

Modeling Time Series Data

Time series functions provide the ability to compare business performance with previous time periods, allowing you to analyze data that spans multiple time periods. For example, time series functions enable comparisons between current sales and sales a year ago, a month ago, and so on.

Because SQL does not provide a direct way to make time comparisons, you must model time series data in the Oracle BI repository. First, set up time dimensions based on the period table in your data warehouse. Then, you can define measures that take advantage of this time dimension to use the AGO, TODATE, and PERIODROLLING functions.

BSO is preferred to ASO in the following scenarios:

* Top-down planning and allocation (Sales Forecasting)

* Cost Allocations across products and customers (Profitability Analysis)

* Currency conversion, inter-company eliminations(Financial consolidations)
