Recent developments in time-domain astronomy use a large amount of data for gaining domain-specific information. The ever increasing data size and different data models require the development of new ideas to manage such data. The data type varies from the images of astronomical bodies, unstructured texts and structured (relations and key-values). There are many astronomical data repositories that manage such kind of data. Palomar Transient Factory (PTF) is one such data repository which has large amount of data with different varieties. Managing such variety of data in a single database can have many performance, growth and scalability issues. In this paper, we propose a prototype system for demonstrating the advantages of using Polystore Database System with a scientific workflow based query system.
