toaster: Big Data in-Database Analytics with Teradata Aster

Share:

A consistent set of tools to perform in-database analytics on Teradata Aster Big Data Discovery Platform. toaster (a.k.a 'to Aster') embraces simple 2-step approach: compute in Aster - visualize and analyze in R. Its `compute` functions use combination of parallel SQL, SQL-MR and SQL-GR executing in Aster database - highly scalable parallel and distributed analytical platform. Then `create` functions visualize results with boxplots, scatterplots, histograms, heatmaps, word clouds, maps, networks, or slope graphs. Advanced options such as faceting, coloring, labeling, and others are supported with most visualizations.
