University of Oxford

Oxford, UK

  • Master of Science in Computer Science, Grade: Distinction

  • Thesis: Single-round vs Multi-round Distributed Query Processing in Factorised Databases

    • Designed and implemented in C++ a distributed query engine, coined D-FDB, that evaluates join queries in a distributed setting. In contrary to traditional systems that use flat relational tables, D-FDB uses data factorizations (f-representations) end-to-end exploiting their theoritical size-bounds against flat data to minimize the total query execution time.

    • Additionally, I developed several serialization and bit-compression techniques to efficiently transmit data factorizations over the network whilst retaining the factorization compression levels.
