Ovum takes a deep-dive technology audit of Vertica's Analytic Database that is designed specifically for storing and querying large datasets. Ovum states, " Vertica's differentiator is that it combines a columnar database engine with massively parallel processing (MPP) and shared-nothing architecture, aggressive data-compression rates, and high availability. Column-based databases can be slow deleting and updating data, and Vertica addresses this by using a hybrid store that handles write, update, and insert operations. The store also makes the data available for queries in-memory. Ovum believes that Vertica's technology could be applicable across a range of markets among companies that have a mix of analytical requirements."
