Today I want to react to an article that claims that Relational Algebra Is the Root of SQL Problems in which the author hand-waves the following position:
SQL becomes more a hindrance to data manipulation than an efficient tool. SQL’s greatest problem isn’t in the implementation level, but at its theory foundation. The problem can’t be solved by application optimization. Relational algebra isn’t sophisticated enough for handling the complicated data manipulation scenarios.
