BSO application

BSO-block storage option

support a wide range of calculations, including forecasts.

allocations, and aggregations.

BSO storage are limited to about 10 dimensions and member counts .

BSO cubes typically contain fewer (and smaller) dimensions than

aggregate storage (ASO) cubes.


2/17

Business requirement of BSO application

Sales Forecasting- Top-down planning and allocations

Profitability Analysis- Cost Allocations across products and customers .

Financial consolidations- Currency conversion, inter-company eliminations


3/17

ASO Application

ASO-Aggregate storage option-it can support about 20 dimensions

It use multidimensional functions rather than procedural scripts to

perform calculations.

Aggregate storage databases enable dramatic improvements in both

i.e database aggregation time and dimensional scalability.

The aggregate storage kernel is an alternative to the block storage kernel.

it typically address read-only, rack and stack applications that have large

dimensionality and Customer Analysis


4/17

Business requirement of ASO application

Customer Analysis- Many dimensions, million of customer

Procurement Analysis- Many products across many customers

Logistics Analysis- Near real-time information on product shipments.

Data and Metadata

Data is nothing but value or collection of information (metedata).

A data is individual facts, statistics, or items of information.

Metadata (metacontent) are defined as the data providing information

about one or more aspects of the data, such as

Means of creation of the data Purpose of the data

Time and date of creation

Creator or author of the data

What is dimension

A dimension represents the highest consolidation level in the database

outline.

The database outline presents dimensions and members in a tree

structure to indicate a hierarchy relationship.

Example

Standard dimension

Standard dimensions represent the core components of a business plan

and often relate to departmental functions.

Typical standard dimensions: :

Time,

Accounts, Product Line,

Market,

and Division.

Dimensions change less frequently than members.

Essbase allocate storage for standard dimension member


10/17

Dense dimension

A dimension which has the high probability that data exists for every

combination of dimension members.

Most multidimensional databases may also contain dense dimensions.

It can used to store the high density data

dense is a property of the values of an attribute. Example:-


11/17

Sparse dimension

A dimension which has low probability that data exists for every

combination of dimension member.

Data is normally stored in sparse form.

Sparse is a property of the values of an attribute.

Example:


12/17

Attribute

An attribute dimension is a special type of dimension that is associated

with a standard dimension.

Essbase does not allocate storage for attribute dimension member.

it dynamically calculates the members when the user requests data

associated with them. Example:- Through attribute dimensions, you group and analyze members

of standard dimensions based on the member attributes (characteristics).

Account dimension

It specifies the data to be collected from budget planners.

such as profit and inventory.

Example:-


15/17

Time type dimension:-

Defines the time periods for which you report and update data.

.The time dimension enables several accounts dimension functions.

such as first and last time balances.

Example:-


16/17

Currency type dimension

This dimension type is used only in the main database and is only for

currency conversion applications.

Separates local currency members from the base currency defined in the

application.

The base currency for analysis may be U.S. dollars.


17/17

Country type dimension

It contains data about where business activities take place.

In a country dimension, you can specify the currency used in each

member.

Example:-

Canada has three marketsVancouver, Toronto, and Montreal, which usethe same currency, Canadian dollars.
