... I haven't explored it, but I plan to. The process models themselves need modeling, but they need to describe the data that's passed in, out, and between...
Hi, Besides the traditional use as a modeling methodology for creating database schema, has anyone explored the use of Object Role Modeling methodology and...
... No, I mean that I can get Oracle Express Edition to test with. For NORMA, you need VS 2005 Pro - I wasn't talking about that. ... As in standard SQL -...
