The Architects group in Kewill Product Development have been evolving a model reference architecture for the next generation products that will offer cutting edge features to our customers. NoSQL databases are one of the key components of the new architecture; though we already use them in our existing product suite, they will have an enhanced role to play in the future. We are going with MongoDB. Having been used to relational databases for most part of my career, the NoSQL flavor is an interesting and welcome change to application development. To get a first hand feel for MongoDB, I wrote a couple of newbie Hello-World programs each for inserting into and fetching data from MongoDB and MySQL.
