SQL is fairly easy to learn when compared to regular programming languages like Java. Although, you get the hang of the basic syntax within a day or two, it would take about a week to become comfortable with writing queries (joins, inner queries, unions etc.) While a SQL query does only a single operation -- a create, fetch, update, or delete -- PL/SQL lets one write stored procedures, triggers etc. which are equivalent to writing methods in a programming language. A stored procedure executes some logic, makes use of variables, usually fires multiple SQL queries and may even call other stored procedures. MS Access is not used as a database in corporate environments anywhere. You'll need to learn one of Oracle, SQL Server, DB2, Sybase, MySQL, or PostgreSQL.
