In continuare prezint un sumar al celor spuse iar la final sumarul prezentat chiar de vorbitor (in engleza).
Perspectivele pentru Oracle in partea de programare par a fi urmatoarele:
- Suport in partea de middleware pentru EJB3 (session beans si messages driven beans) si pentru noul API standard pentru persistenta numit JPA (entity beans din EJB3).
- Via EJB3 se ofera suport pentru cele doua paradigme:
- request/reply – service oriented design pattern style – SOA (expunere de servicii - session bens, webservices)
- publish/subscribe - event driven style – EDA (cozi de mesaje – implementari de JMS, eventual message driven beans drept listeneri)
So, in summary, from a programming model point of view, we believe there are three important trends. The combination of AJAX, JavaServer Faces and Web Tool to provide a much richer model for users to access applications and work with each other. Second, the programming model with the emergence of lightweight containers, OSGi and the Java Persistence API providing a much simpler model to build business logic and deploy them on lightweight containers or modular containers. Third, the combination of grid computing technology for both compute grids as well as data grids and our acquisition of Tangosol provides us an operational fabric to support very, very high scalability and transactional applications using that are built to this programming model.
