Task 20 : The SOA approach

Within this document the SOA will be examined and explained in the context of the WebPA project. The first definition will be what SOA represents. From this discussion of the basic principles will be covered with regard to the guiding principles surrounding SOA to the specific architecture principles. From this point the available SOA technologies are identified and examined. The overall advantages and disadvantages of the system can be found in Appendix 2 – A Comparison of Web Service Technologies. One of the most important aspect of SOA to the WebPA project are the existing frameworks and specifications that can be utilised. This encompasses the relevancy of some of the ELF projects to WebPA. This document also covers the other considerations that must be taken into account with regard to SOA. Finally the document is concluded and the recommendations for the project are made. Through out the document a high number of acronyms and abbreviations are used. In most instances within the body of the document where an acronym is used it is explained at that point. However, to ensure that the reader can understand all acronyms a glossary is included in Appendix 1 – Glossary.
