So, what are the basics of such a framework that provides you the ultimate business power? Such a platform provides abstractions. Programming and business abstractions – about these later, a few lines below. Next to it, it implies a prescriptive architecture (ok, with some flexibility, but in general terms, it implies). It should (or probably, would) be suitable for the development and in today’s continuously deployed world also for deployment of the business applications – on demand, on premise, on mobile. Characteristics of such an application? Distributed, service oriented, cloud powered. Tend to be from simple one screen apps to huge, 1000+ forms, 500+ tables, millions of business logic LOC beasts (should you think of SAP here?). Part of the abstraction, they do have some repeated patterns, that the framework should fulfill, like – UI: setup, data entry, reporting, querying, process initiation; logic micro patterns: data types with composite ones like currency and quantity; logic low level patterns: defaulting, validation, calculated values, sequences; high level patterns: symmetry (a sales order is someone else’s purchase order), workflow. Of course support for edit all of these at runtime, have multi-tenant (SaaS) capability. These characteristics altogether are the ones that drive the abstractions we make. Now compare this to what you get when you try to stop at having an ORM with bound UI controls. And we haven’t touched BI yet. Next time I’ll try to drive into the value chain; oh boy, that can get pretty nasty and complex rather quickly.
