<br /> • Data Architecture -The data azchitecture is the blueprint for organizing the data needed to <br /> support the information requirements of the County. It uses the function model to consolidate and <br /> standazdize the process by which data is organized and referenced throughout the County. [n <br /> developing the function model, each process is analyzed to determine the information needed to <br /> perform that process. Information requirements that are used frequently together aze grouped into <br /> subject azeas. Subject azeas aze the ideal structures for logical database organization. The <br /> objective is to support the greatest number of processes with the smallest number of databases. <br /> The County's Plan does not provide a data architecture for the County. <br /> • Application Architecture -The application architecttre defines the integrated, non-redundant set <br /> of automated information systems needed to support the County. It facilitates the coordination of <br /> a lazge number of system development projects and provides a basis for defining application <br /> development projects. The application azchitecture is derived from the processes contained in the <br /> function model. Each process that could be supported by automation results in the definition of <br /> an application system. The application architecture represents the tazget environment towazd <br /> which all future systems development can be directed. <br /> No application architecture is provided by the County's Plan. The Plan makes <br /> recommendations regardirsg individual applications. Afunctional listing of applications is <br /> provided to identify which applications may cross departmental boundaries. <br /> • Assessment of Existing Information Systems -The County maintains a significant investment <br /> in existing application systems and technology. An inventory and assessment of existing <br /> applications, in addition to an inventory of current projects and current databases and fies, helps <br /> to determine the strengths and limitations of each. It provides the County with a baseline for <br /> future system improvements, including: <br /> A profile of existing automated applications systems and an assessment from both a technical <br /> and functional perspective. <br /> Identification of application systems that aze currently funded and in process. <br /> Comparison of the current applications and projects to the desired application azchitecmre to <br /> identify gaps and deficiencies. This comparison is called a gap analysis. <br /> Profile and assessment of existing technology components (computer systems and networks). <br /> Profile of the major databases and files. <br /> The County's Plan provides a listing of information systems. However, technical and <br /> functional assessment of these systems are not adequately provided. <br /> • Project Plan -For strategic planning purposes, the project plan provides the road map for <br /> implementation of new systems for the County. Each project must be defined insufficient detail <br /> to allow its evaluation based on the criteria such as: <br /> Support for County objectives and critical success factors <br /> Resource constraints <br /> -17- <br /> <br />
