DataCommandr Engine is a C# library for data integration, transformation and analysis. DataCommandr is intended for defining (potentially highly complicated) data mashups, that is, new data that is derived from the input data by applying various transformations. In this sense, it pursues the same goal as conventional query languages (like SQL) and data processing frameworks (like MapReduce). The unique distinguishing feature is that DataCommander uses a novel column-oriented approach where new data columns are defined in terms of other data columns. It is opposed to most other languages and frameworks where new data tables are defined in terms of other data tables. In particular, it is an alternative to such conventional approaches as SQL-like languages and MapReduce
