Umbra
Umbra is designed to process data at line-speed under all circumstances. In memory, we process hundreds of gigabytes per second while gracefully falling back to flash-based storage. Using data-centric code generation, parallel execution, and advanced query optimization techniques, Umbra executes the most complex queries with ease. Read more ...

HyPer
HyPer is a hybrid online transactional processing (OLTP) and online analytical processing (OLAP) high-performance main memory database system that is optimized for modern hardware. Read more ...
C-Chain
C-chain is a high performance, but lean variant of Blockchain. Classical Blockchain techniques experience a surprising hype, although they have a number of very serious drawbacks like Read more ...
Lingo DB
LingoDB is a cutting-edge data processing system that leverages compiler technology to achieve unprecedented flexibility and extensibility without sacrificing performance. It supports a wide range of data-processing workflows beyond relational SQL queries, thanks to declarative sub-operators. Furthermore, LingoDB can perform cross-domain optimization by interleaving optimization passes of different domains and its flexibility enables sustainable support for heterogeneous hardware.

Linked Data Benchmark Council (LDBC)
EU FP7 project to create benchmarks for RDF and graph databases. Read more ...
CH-benCHmark
The CH-benCHmark is a new benchmark. It bridges the gap between the established single-workload suites of TPC-C for OLTP and TPC-H for OLAP, and executes a complex mixed workload. Read more ...

Completed Projects

rtSOA
The rtSOA project aims at making constrained nodes first class citizens in a service oriented architecture for industrial automation. A primary research goal thereby is the development of concepts for (semi-)automatic service composition to support higher flexibility in re-tooling and quick adaptation to failures in the automation chain.
