PowerHouse Portable Subfile

With a PowerHouse
PowerHouse 4GL portable subfile.
In Cognos Transformer, specify the portable subfile dictionary (.psd) file or the
data (.ps) file. Accept the default Character set or specify an alternative. For more
information, see "PowerHouse Data Source Parameters" on page 43.

Fixed-field Text

With Fixed-field text, input values are obtained from a text file with one record per
line. Each field starts at the byte immediately following the preceding field; the
width of each field occupies a specified number of bytes. Each row ends with a
text line delimiter.
In Cognos Transformer, manually add columns to your data source by specifying
the position and length, in bytes, of each column in the source file. Accept the
default Character set or specify an alternative.

Fixed Field and Record Without CR LF

With Fixed field and record without CR LF, input values are obtained from a text
file. Each field starts at the byte immediately following the preceding field; the
width of each field occupies a specified number of bytes. The record end is not
marked by a text line delimiter.
In Cognos Transformer, manually add columns to your data source by specifying
the position and length, in bytes, of each column in the source file. Accept the
default Character set or specify an alternative.

Designing Successful IBM Cognos PowerCubes

The most successful business intelligence applications are designed with well
planned models. This includes an analysis of how the data in the models will be
used by report and analysis users. Consider the following concepts when
designing PowerCube models for use in IBM Cognos BI products.

Conformed Dimensions

Dimensions are conformed when the data values that come from the original data
sources use the same business keys, or source data, that is used in other packages
or models in your IBM Cognos environment. Conformed dimensions allow your
users to combine or cross data sources successfully when their business needs
require that they do so.
For example, consider that your goal is to drill through to product line information
between two reports. The first report is based on a PowerCube package, and the
second report is based on a relational package. Each product line in the relational
package should include a business key, or unique identifier. In the PowerCube
model, the Source value for each category in the Product Line dimension should
reference the same data value as the business key in the relational package.
When the same business keys and source values are used throughout your IBM
Cognos application data, end user success with reporting and analysis will increase
substantially.
