UUID in Mule ESB

Most of the times in enterprise applications its required to trace the exection of a transaction so each transaction is given a unique identifier of its own. This unique identifier can be java.util.UUID. I have used this unique identifier in Mule ESB in the following way. I assign it to local variable and then use it as an identifier for the transaction and log it at every point with the normal logger output. This helps me trace the transaction.

NoSQL Database MongoDB

I have been spending quite sometime with the NoSQL database-MongoDB, should say it offers quite a punch. Shifting my tthinking from the relational model of the database to the document model was quite tough at first but as i progressed with the DB patterns it was easier to understand the document model and had a much less learning curve compared to RDBMS. With all the buzz going around on NoSQL Vs RDBMS, the coming days will be interesting to watch in the integration space and how these NoSQL database get supported in vendor COTS products. The story of how the map-reduce algorithm came from the Roman period was amazing. I didnt like using the command line tool hence i started using the UMongo database client in my windows machine. Im in the process of trying to use the MongoDB component in apache camel.
