But although space-based middlewares are simplifying the development of
distributed applications, most of them can not be used for complex
applications because they do not provide an essential enterprise feature: distributed
transactions. Other middlewares which already provide this feature often
rely on old commit algorithms which are having known problems in certain
scenarios. Therefore this work provides a flexible and concurrent distributed
transaction model which is aligned on the space-based computing paradigm.
The new model supports long-lived transactions and provides a high degree of
consistency. As a positive side effect the evaluation shows that in certain
scenarios the new transaction model performs better than a standard local
transaction system.

Due to the increasing complexity of software systems there comes the need of
technologies that help developers to simplify the programming process.
Middleware systems in general can offer this functionality. One type of middleware
is based on the Space Based Computing paradigm. It offers a shared
memory data space that can be accessed concurrently by different users. The
eXtensible Virtual Shared Memory (XVSM) architecture uses this approach and
provides an easy extendable solution for developers. Actual implementations
are based on Java (MozartSpaces) and .NET (XCOSpaces). With the rapid
growth of smartphones based on Apples iOS operating system comes the need
of an implementation for that platform. The goal of this thesis is the provision
of an implementation for the iOS platform that is fully compatible to Mozart-
Spaces, the actual reference implementation of XVSM. A research process
concerning possible solutions is followed by a ready to use implementation for
software developers. The output is evaluated by different kind of performance
benchmarks. The compatibility to MozartSpaces is evaluated by integration
tests and presented by an application scenario where the new implementation
works hand in hand with MozartSpaces. The new implementation is based on
the native programming language of Apple, Objective C and works well in
association with MozartSpaces.
