Introduction
DBScale is a software that can synthetically scale the database of an enterprise’s database application. DBScale ensures the synthetic databases generated preserve the data characteristics of the original database and the query characteristics of the original database applications. Therefore, one may use DBScale to create an up-scaled version of its production database to predict the scalability of its applications in her own production environment or in a cloud service environment.
DBScale is currently in development and is expected to be ready by mid 2013.
DBScale is based on the most advanced database generation techniques, published at top academic conferences and journals:
- Eric Lo, Nick Cheng, Wilfred Lin, Wing-Kai Hon and Byron Choi: MyBenchmark: Generating Databases for Query Workloads. To appear in the VLDB Journal.
- Eric Lo, Nick Cheng, and Wing-Kai Hon: Generating Databases for Query Workload. PVLDB 2010, Singapore.
- Eric Lo, C. Binnig, D. Kossmann, Tamer Ozsu, Wing-Kai Hon: A Framework for Testing DBMS Features. The VLDB Journal 2009.
- Carsten Binnig, Donald Kossmann, Eric Lo, M. Tamer Özsu: QAGen: generating query-aware test databases. SIGMOD Conference, 2007.
Workable Environment
DBScale functions properly with the following environment:
- OS: Windows XP / Windows 7
