As far as my knowledge is concerned alias are used for duplication of names.But where as contexts are used to resolve the loops concept, because using loops we can't determine which way to follow.If we have loops it produces undetermined results.

Aliases

Which are logical pointers to an alternate table name. This command is dimmed until you select a table within the Structure window.You can define aliases to resolve the loops that Designer detected in the universe structure.This feature works only if you have defined at least one join and all the cardinalities in the joins have been detected.

 

Context

 

Can be used to resolve loops in the universe, You can create contexts manually, or cause them to be detected by Designer. When contexts are useful, Designer suggests a list of contexts that you can create.

context is nothing but specifying the name of the path

the place where u cannot resolve the loops with allias there comes concept of context


alias is nothing but the duplicate name of some other table

Context is basically used when we will have conformed dimension in the loop........
