Active Database Integration in Grids

NeSC Research Seminar Series
Speaker: 
Alex Wöhrer

A focus of Grid computing are data intensive applications. Additionally, database management systems (DBMS) are gaining on importance in many scientific disciplines for publication of research results.The employment of Service-oriented-Architecture (SoA) raises the question of how DBMSs and their built-in technologies can be best utilized in such environments. A common way is to pull out all required data for a certain task from a source and process it service side far away from the original source. This approach is characterized by a passive usage of the DBMS as a pure data provider which implies significant overheads.

The talk will describe an active usage approach of a DBMS by relocating distributed query processing functionality inside it. This utilizes the existing database technology, puts just the interface code at the service level while the data processing code resides at the database level and uses a push mechanism for the result data. The advantages are less overheads and data movement as well as increased data locality. A proof of concept implementation is evaluated by comparing it against OGSA-DQP.
