An integration tab to allow import and export of the architectural data is provided, as are a wizard based installer and update scripts. The tool can be installed in either stand alone or multi user mode, with multi user the use of a data base such as MySQL is required.
The Essential Meta-Model, a framework-independent set of semantic definitions of the building blocks and relationships of an enterprise, spanning business, information, IT applications and technology platforms.The Essential Project has been developed for use in conjunction with a variety of Enterprise Architecture approaches and Enterprise Architecture framework. It launched its first version in March 2009. The Essential ProjectĮssential is a free, open source tool by Enterprise Architecture Solutions Ltd, a UK-based EA consulting company. There are two main tools that provide the modelling capabilities necessary, combined with the means for multi user capture of the architecture and the ability to extract and report on the information captured. Recently a number of Open Source EA Tools have appeared, providing an alternative to the commercial tools on the market. The ability to extract repository information to support various stakeholder needs.The ability to create or import models and artefacts.Provides support within the repository for relationships among and between the objects in the above viewpoints and solution architecture.A meta model that supports business, information and technology viewpoints as well as the solution architecture.The Gartner Group has defined the requirements of an EA tool as being:. Requirements of an enterprise architecture tool
There are a number of underlying issues for organisations that use Visio, PowerPoint, Excel and/or SharePoint rather than an EA Tool the information captured quickly becomes out of date, the ability to quickly and easily re-draw a different view of the information is not available, the meta-model must be manually enforced. In a 2009 report over 50% of respondents claimed not to be using a commercial EA Tool, with many making use of Visio, PowerPoint, Excel and/or SharePoint only and a 2008 survey indicated the cost of licensing as the main barrier for EA Tool adoption. Traditionally, enterprise architecture tools are proprietary and have a reputation for being expensive to purchase, customise and run. The information is captured and modelled to allow senior management to report on and analyse it, allowing effective and timely decision making regarding tactical projects and strategic change initiatives across the organisation.Įnterprise architecture tools are used to aid the enterprise architect in a number of ways allowing them to capture information regarding the enterprise, undertake modelling in all domains, capture the links between the various artefacts, provide a meta model to standardise the capture and hold this information in a repository to allow interrogation of the information, for example in the form of standard or ad-hoc reports.
The organisation is usually broken down into a number of layers business, information, application and technology and these are viewed through a number of abstractions, conceptual, logical, and physical.
