Welcome to DIMA

• Today, modern database systems in global enterprises manage 400 million accounts at a rate of 10,000 transactions per second.
• Data-warehouses store billions of structured records, amounting to several Petabytes (≈ 10¹⁵ Bytes) of data.
• Corporate intranets organize data contained in millions of pages.
•  By some accounts, it is estimated that the World Wide Web (WWW) has over 200 million websites with more than 50 billion web pages. Dynamically generated content and Web 2.0 mashups exponentially increase the amount of information available.

The Database Systems and Information Management (DIMA) group at the Technische Universität Berlin conducts research in the management and optimal processing of large-scale (semi-)structured data and huge collections of unstructured documents. This involves exploring systems, architectural designs, and their implementation to enable information management on the web-scale. In order to meet this grand challenge, we will need innovative solutions that address each step in the Information Management Lifecycle. These steps include information modeling, information extraction, data cleansing, integration of heterogeneous data sources, efficient query processing, archiving, and retention management.
