Hi,

Both are used to solve Join path problems.

Especially, Contexts are used to solve Chasm traps and Aliases are used to solve Fan traps.

Thanks

Sri.

HiAlias can be used when there is less complexity in loops and few fact tables where as Context can be used to resolve loops when more fact tables are present in the universe design.

when we create alias or context , we end up with Objects. If the objects you created is sounds like same then you can go for context. if the objects sounds different then you can go for alias. The main thing is that the best way to resolve the loop is alias.

hi , this is srikar.my suggestion is

1. we can go for alias when ever there is multiple usage of that particular table.....else go for contexts..

2.we use contexts ... when ever there is a many to one relationship between 2 fact tables and 1 look up table(nothing but charm trap)

3.if there is a necessary to use more than 1 alias to solve the loop..then go for contexts....
