The DMC - Datamartist Data Canvas File is a document designed and developed by Datamartist. This file was designed to function as a data profiling tool. This tool allows the user to manage, analyze and combine data files from various sources. This particular file is diverse and highly functional, allowing it to perform numerous tasks. Not only can this file contain sets of internal data, it is also capable of containing data transformation specs, in the form of transformation blocks and the connections between the two. 250,000 values is the maximum allotment of values per data set on each file.
These particular files have a suitability for small to mid-sized datasets and most commonly and best used for creating reference datasets with the primary goal being testing. However, it is possible to reference larger datasets and store them externally in a separate cache, making the data more readily accessible.
