ABSTRACT This article studies current developments and trends in the area
of capital market systems. In particular, it defines the trading
lifecycle and the activities associated with it. The article then
investigates opportunities for the integration of legacy systems and
existing communication protocols through distributed integrated services
that correspond to established business processes. These integrated
services link to basic services such as an exchange, a settlement, or a
registry service. Examples of such integrated services include pre-trade
services (e.g., analytics) or post-trade services (e.g., surveillance).
The article then presents the various levels of integration in capital
market systems and discusses the standards in place. It establishes that
most interactions occur at a low level of abstraction such as the
network (e.g., TCP/IP), data format (e.g., FIX, XML), and middleware
levels (e.g., CORBA). Finally, the article discusses a software
development methodology based on the use of design patterns. These
design patterns address the essential aspects of managing integrated
services in a technology-independent fashion. These aspects are service
wrapping, service composition, service contracting, service discovery,
and service execution. The objective of the methodology is to facilitate
the rapid development of new integrated services that correspond to
emerging business opportunities

    ABSTRACT: Due to immense amounts of data being generated from financial markets in many different formats, professionals and academics face interoperability problems when analysing such data. This paper proposes a data model that gives a coherent view of the information available from financial market data repositories. The novel features of this data model include: modelling the behaviour of an electronic market as an extensible event-based class hierarchy, and using ontologies to represent financial data as a set of inter-related and meaningful events. Using this data model, we develop interoperable web services that process the data at a high level of abstraction using a Service-Oriented Architecture.

    ABSTRACT: The eXtensible Markup Language (XML) has been widely adopted for information exchange across various networks due to flexibility providing common syntax for messaging systems. Excessive use of XML as a communication medium created an aligned interest in the level of security provided for those XML-Based systems. Many security concerns have been tackled by the World Wide Consortium (W3C) creating the "XML Encryption Syntax and Processing" Recommendation [4]. This study presents a new architecture to handle received XML messages from various systems, on one hand suggested architecture is focused on classifying received XML messages (sensitive and non-sensitive) data to define which parts of the XML document to be encrypted and which to be forwarded to another module in suggested system to handle message composition, On the other hand the architecture is focused on securing XML messages by encrypting flagged XML parts each with different type of encryption depending on data sensitivity and importance level defined, this stage uses an approach based on W3C "XML Encryption Syntax and Processing" Recommendation. As a result, study aims to improve both the performance of XML encryption process and bulk message handling to achieve data cleansing efficiently.
