Udi talks to Paul Preiss, President and Founder of the International Association of Software Architects, about the field of IT Architecture, the value IASA brings to architects, vendors, and corporate IT, as well as the various training programs available including the free Skills Library--over 600 pages of articles written by architects for architects.
Udi returns to the topic of Entity, Activity, and Process services and compares their usages as top-level SOA elements and as implementation details of the application architecture inside a business service.
Udi discusses the different options that are available for passing data between a client and a service, as well as common pitfalls around trying to use the same objects for both presentation to the user and persistence to the database.
