Best Practices while creating a Universe.
Here i am mentioning some best practices while creating a universe :
1. Common Points in Universe Conversion
- Check all parameters and settings after conversion
- Sometimes they change, though I haven’t seen this with SP-04
- Run the Integrity Checker after conversion
- Make sure that all joins and objects still parse Correct any issues
- You can choose your Default settings for the Integrity Checker
Preference -> Information Design Tool -> check Integrity
2. Welcome to the Family
- Use Families to keep track of your tables
- One family for each fact, and related tables One family for conformed dimensions One family for Alias tables
- One family for Derived tables
- You can use a comment box for a legend of colors Be consistent with colors across all universes
3. Did You Know You Could Color Code Descriptions?
- That’s right! Use HTML Tags to color code the descriptions of objects.
- A good universe has 300 to 500 objects, but may have up to 700 objects
- This depends on the technical ability of the users
- Unless you need a multi-source universe, create it as a single-source universe
- This avoids the overhead of using the Data Federation layer
- Every object, without exception, should have a description
- Descriptions must be in user friendly terms
- Don’t use underscores in anything seen by a user
- Develop, and stick to, naming conventions
- Document everything you do!
- Someone else may need to continue your work
- Use user friendly names for all universes, folders, and objects
- Have a team of power users check your work throughout the development process
- Create all LOV s from dimension tables, even if you have to create them
- Alternately, you can create static LOV s
- Give LOV s meaningful names
- This will help when troubleshooting LOV issue
Hope these above mentioned points will help while creating universe.
