|Abstract: ||Distributed software systems that are designed to run over workstation machines
within organisations are termed workstation-based. Workstation-based systems are
characterised by dynamically changing sets of machines that are used primarily for
other, user-centric tasks. They must be able to adapt to and utilize spare capacity when
and where it is available, and ensure that the non-availability of an individual machine
does not affect the availability of the system.
This thesis focuses on the requirements and design of a workstation-based database
system, which is motivated by an analysis of existing database architectures that are
typically run over static, specially provisioned sets of machines.
A typical clustered database system — one that is run over a number of specially
provisioned machines — executes queries interactively, returning a synchronous
response to applications, with its data made durable and resilient to the failure of
machines. There are no existing workstation-based databases. Furthermore, other
workstation-based systems do not attempt to achieve the requirements of interactivity
and durability, because they are typically used to execute asynchronous batch
processing jobs that tolerate data loss — results can be re-computed. These systems use
external servers to store the final results of computations rather than workstation
This thesis describes the design and implementation of a workstation-based database
system and investigates its viability by evaluating its performance against existing
clustered database systems and testing its availability during machine failures.|
