Access Views through Public Synonyms

Question

Hi Friends,
I have query need to clear. My current application is running on a schema *(s1)* associated with workspace *(w1)*. Now i have made one more schema *(s2)* in the same workspace *(w1)* where i have to create new tables.
The thing is i want to use few tables column of s1 on s2. What will be the best practice for this. I have made views of columns of s1 schema and now i am thinking to create public synonym in s2 schema to access those views of s1 schema. Just want to confirm any changes or updates made on forms or report made on synonym of s2 will reflect in the base table (which is table of s1). Want to clear the concept of synonym through this. I am sure it will not update the table of s1 schema because i have made synonym of that in my s2 schema and for all page creation i am using objects of s2 not objects of s1.
Would like to hear from you experts on this. If you have some other better soln for this, do suggest me. All my intension is to not update the tables of s1, just to use the required columns of s1 schema objects and use it in s2 schema
Regards

Hi,
A synonym just helps you to avoid using the schema name before the object name. If you want to use some columns from tables in s1 just do the following:
1. Create the views
2. Create a role for that privilege (for example: select_s1_role), grant select to this role over the views and assign it to s2.
3. Create the synonym in s2 to s1 views (just to avoid put s1. before the view name).
For the steps above is required that s1 and s2 have the proper system privileges.
Kind regards,
