Best Practices- Universe Design

Quick start and Setup Gino Scheppers16/12/2010

How to test the template universe

Open the Oracle template universe in designer (3.1 or higher)

Change your connection to a valid Oracle (G10) Database

Start playing with the following objects: Generic Date Table/Date -object Corresponding filters:

‘Date-LOV-filter-example’ ‘Date - Prompt example’

Or use a between condition in combination with the [Begin Range] & [End Range] objects

Steps to change a existing universe (summarized)

1. Open the Oracle-template-universe and change the connection to a valid Oracle database.

2. Open your target universe3. Copy and past the derived table with name

‘GenericDateTimeDimension’ to the target universe

4. Copy/Past the ‘Miscellaneous (Date Time Objects)’ class from the template universe to the target universe.

5. Disable all LOV for all objects in the above class6. Create a filter-prompt object for every date/time

object where an ad-hoc ‘List of values’ is needed. (check the filter-example in the Generic Date table class)

7. Recreate (if necessary) the LOV of the GenericDateDimension object

Steps

recreate the LOV with following objects and parameters.

Tip:you can use an additional sort object to sort the LOV

Also need a super generic date table?

Steps: Copy/paste the derived tables (GenericDateTable & Holidays) to

your target universe Copy the ‘Generic Date Table’-class to your target universe Customize (disable the LOV’s) the objects in the above class. Adjust the derived table ‘Holidays’ with your own holidays

Final step

Learn the End-User the ‘ultimate between-trick’ (in 4 easy steps)

1. Drag & drop the date/time object you want to query in the condition panel

2. Select a between condition3. Select a [Begin Range] object from the

Miscellaneous (Date/time objects) class4. Select a [End Range] object from the

Miscellaneous (Date/time 5. Run the query.

That’s all folks

It’s free! But a small donation to my PayPal account gino.scheppers@telenet.be is…

Oeps, forgotten to mention

the ‘Miscellaneous (Date Time Objects) [GMT]’ class is a bonus class, it converts ‘Europe/Brussels’ daylight saving time to GMT.

In case the ETL boys has forgotten to convert GMT to Local time in there ETL process.

Oeps, and a DateTimeDimensionDB2Template-universe is also include!
