Many of the new online and device-oriented application models require a high degree of operational and development agility such as unlimited elastic scale and flexible data models. The nascent NoSQL market is aiming to address these requirements but is extremely fragmented, with many competing vendors and technologies. Programming, deploying, and managing NoSQL solutions requires specialized and low-level knowledge that does not easily carry over from one vendor’s product to another. The SQL market on the other hand has a high level of maturity and at least conceptual standardization, but relational database systems were not originally designed for these requirements.
However, in contrast to common belief, the question of big versus small data is orthogonal to the question of SQL versus NoSQL. While the NoSQL model naturally supports extreme sharding, the fact that it does not require strong typing and normalization makes it attractive for “small” data as well. On the other hand, it is possible to scale relational SQL databases.
In this presentation, I will provide a short introduction to some architectural patterns that SQL-based solutions have been using to achieve scale and operational agility, contrast them with the NoSQL paradigms and show how SQL can be augmented with NoSQL paradigms at the platform level by using SQL Azure Federations as an example. I will also show how NoSQL offerings can benefit from the lessons learned with SQL.
What this all means is that NoSQL, BigData and SQL are not in conflict, like good and evil. Instead they are sometimes overlapping, but often complementary solutions that benefit from common paradigms addressing different requirements and can and will coexist.
