"Vendez vos actions en bourse et achetez un chien : Il n'y a plus que ?a qui rapporte" (Laurent Ruquier) Month by month or 1 by 1 Yesterday I spent some time improving my start page. You can now browse my published articles month by month and one by one.

It's a very nice box. You have 5 CDs of relaxing music. Very Nice. SOA Services Granularity When discussing about SOA a very common question goes about the granularity of services. I have always applied two principles to decide for myself if a service has the right granularity : 1. Does it make sense ? If a Business User of this service reads the service specification, he should be able to understand it. This requires to have servcice specifications in natural language. 2. Is it Human ? Services are ways to request for information. My basic belief is that it should be possible for a normal human being to process that information. I like to think about services in terms of web pages : how would it look like if it was a web page ? (That's probably because I'm a fan of the Semantic Web vision). The rationale is that if the service provides something that is not human (thousands of records) there is room for service re-factoring (by using an iterator for instance). A service that would dump all your emails at once on your screen in one page would be useless. What you want is a service to browse emails titles 20 by 20 and the possibility to open an email by selecting it. In addition you want a search function. Paging, Summaries and Searching are examples of human services. TOGAF Certification Course Completed this week This week I completed a TOGAF 8.1 Certifcation course. This means that I should be TOGAF Certified in the coming days. This is the second Certification I pass this year after the ITIL Certification (Thank you IBM!). TOGAF is about Entreprise Architecture and it's a fascinating topic. I'll blog about the highlights of this TOGAF course soon.
