Peter’s area of greatest technical strength is as a PL/SQL designer and developer. He enjoys building data processing systems using PL/SQL and has used the language with a wide variety of systems. He says “If your data is stored in an Oracle database, PL/SQL is your tool of choice for implementing business logic. It is powerful and versatile, and can support any kind of front-end (user interface) that you would want to imagine. With Oracle’s new APEX application builder, PL/SQL can even be used to develop quite sophisticated web-based systems without the need to pay extra for web development software – it’s all built in to the Oracle database”.
