Data integrity and transactions within SOA

I came accross this article about managing transactions within a SOA environment. There Vinay Singla mentions 4 techniques:
1) Perform the operations that support transactions before the operations that don’t support transactions (technique 2 can help)
2) Use compensating transactions (services must support compensating capabilities)
3) Break the transaction into multiple decoupled transactions
4) Execute the transaction as a long-running transaction

Maybe you think of WS-Transaction and WS-Reliability but these standards have not yet been mature enough.

Another technique not mentioned is the use of Functional/Technical maintenance. In this case when a step is not fulfilled, it will be send to a queue. This will be picked up by maintenance to correct the problem.

I always fancy the most simple solution that decreases complexity for situations that may occur only once in a while, but this depends of course on the requirements.

OSB 10gR3 and SWA and MTOM

This blog is about using soap with attachments and the use of MTOM within the OSB (10gR3). A service is created that accepts a soap with attachment (DocumentService) and translates it to a service that accepts a binary element. MTOM is used for performance reasons for the second. Some notes: * For the use of attachments you need RPC-style document instead of the usual document-style. This due to the fact that the document-style limits a message to a single . * A service can not have both SWA and MTOM within OSB. First a WSDL is setup for the DocumentService: The $attachments variable holds the attachments and the body holds the attachment data. Also other data is stored within the attachment element (see h...

Microservices mindmap

"The tree" - See also   my photo page When you are fairly new within the Microservices land, there are a lot of terms fired at you. So also for my own understanding i have made a mindmap. I think it has a good status now, so that i can share it with you. As always feedback is very welcome ! You can download the mindmap here .

Book review: Data Management at Scale (Piethein Strengholt)

 This blog is a review of the book "Data Management at Scale (See also at bol.com ) Data Management is a hot topic nowadays and this book does a fantastic job at adding value to this topic. It is a must read and one of the few technical books I finished reading in a weekend. The book gives a fantastic overview on how to implement a Data Mesh data architecture. The Data Mesh concept is explained by Martin Fowler here . The book is a good mix between conceptual and implementation architecture level. It gives a lot of examples of how this architecture at scale can work, for both small and big companies. It is practical and I used it to implement it at one of my customers. The book describes an architecture in which the focus is on the DIAL (Data- and Integration Access Layer).  On a high level the book covers the following topics: The key principles for data management at scale - Domain-Driven Design  - Domain Data Stores - Meta data management Ready Data Store The concept ...
