Thank you so much - this is a good help. I'm wondering how you use relational algebra if we should make it from a SQL query instead of a table?

relational algebra gives us some basic ideas before we start writing some complex queries in SQL. the data is manipulated through sql only but relational algebra just gives us some basic ideas-like what tuples,table,data we need.. what are the conditions and all.
