But as is often the case, the theory and potential for a technology is often far different than what is observed in practice.<\/p>\n<p>Very often project run into a kind of data impedance running between the different data sources.  <a target=\"_blank\" title=\"Problems with SOA data\" href=\"http:\/\/www.itnews.com.au\/Feature\/4112,guest-column-expensive-data-pitfalls-in-serviceoriented-architectures-today.aspx\">Problems <\/a>can result when:<\/p>\n<ul>\n<li>Data Structures and service versions change frequently<\/li>\n<li>Data Quality isn&#8217;t consistent and is difficult to measure<\/li>\n<li>Data Sources are distributed both internal and external to the company<\/li>\n<\/ul>\n<p>Non-uniformity of data and formats can make it necessary to write very data-specific transformation algorithms and the specificity of the coding can cause software to be brittle and subject to failure.  This is in fact a weakness of traditional data integration that SOA seeks to solve.<\/p>\n<p>How to overcome this?  Laurie Newman in an ITNews column suggests that SOA architects consider the following data integration elements during in their design:<\/p>\n<ul>\n<li>Data Semantics: The business context behind data definitions for concepts such as customer address, product category, or employee type<\/li>\n<li>Data Quality: Improving the accuracy and consistency of data moving between heterogeneous systems<\/li>\n<li>Data Governance: Data and metadata management, documentation, reporting, and auditing tools<\/li>\n<li>Data Access: Tools to untap structured, semi-structured, and unstructured data in hierarchical and relational databases, mainframe systems, files and documents, and applications<\/li>\n<\/ul>\n<p>Newman argues that without sophisticated Data management tools SOA projects will suffer.<\/p>\n<div class=\"lightsocial_container\"><div class=\"lightsocial_element\"><a class=\"lightsocial_a\"
