Home Services DB Migration

Data base migration

Skillfully executed migration to a modern storage system will help to avoid many risks of further proprietary software maintenance, to optimize the support cost and create a solid foundation for the further development!



At present time public corporations and government structures have a lot of systems, which are built on top of legacy RDBMS such as Oracle, Microsoft SQL Server, IBM DB2, Teradata and others. The use of databases involves a number of problems: legacy RDBMS do not fit well into the ever-growing datasets, that everybody has to process in nowdays, such solutions are either not-scalable at all or the scale price is unacceptable, total cost of these systems becomes enormous.

Base Migration

Data management system transferring from IBM DB2 to MongoDB plus moving business logic from PL/SQL to Java.

Company Experience

TaskData employees have been working for a long time one the industrial enterprise storage system design, implementation and support in the world's largest corporations and they have repeatedly faced with the necessity of a storage migration from one storage system to an alternative. 5-10 years back it was popular to move from commercial RDBMS to the open-source solutions, such as PostgreSQL or MariaDB. We are as an data-oriented company were supporting these initiatives from the very beginning. In nowdays the trend has changed and most of the customers are moving to NoSQL solutions and TaskData experts aready have solid experience in such projects.
