DBTimes was founded in 1992 by Victor Shulman who is the author of the software and the frameworks for Data Warehouse development.


Our flag product, Relational Database View, is being used by hundreds of developers to help them better understand their existing databases and learn the newer ones quicker. Relational Database View is a database diagramming tool with extensive schema search and comparing capabilities.


Our second product, Relational Data Compare allows comparing results of two queries. It is used to find differences in result sets with thousands of rows, works across different RDBMS, and supports several modes of comparing data.


Our frameworks for Data Warehouse ETL implementation are used to substantially shorten productionization of the dimensional model in SQL Server/.Net or Data Lake/Spark environments.
