ATA Data Model: What is a Data Model? • Structured graphical representation of the processes, business rules and information/data interchanged between a manufacturer/supplier and operator
• Modeling methodology and techniques provide information/data in a standard, consistent, and predictable manner in order to manage data as a resource
• Enables re-engineering of business processes and product life-cycle information targeted to achieve a world-wide accepted Integrated Data Environment
ATA Data Model: What is a Data Model? • Critical Success Factors for the industry standard Data Model: Generic - facilitates facilitates development development of systems of varying varying purpose, scope scope and complexity precise - representation representation of data is complete, complete, correct, correct, 4 Rigorous and precise consistent and usable Concise - facilita facilitates tes improved improved understandi understanding, ng, communicat communication, ion, consensus consensus 4 Concise and validation functional requirements requirements rather rather than physical or 4 Conceptual - represents functional organizational constraints 4
• Flexible Flexible - supports supports phasing phasing of the life cycle, cycle, i.e., M&E model to be followed by Flight Ops, Training, Material Management
• Applic Applicati ation on - use of the the model model enab enables les improve improved: d: Business process analysis 4 Applications development 4 Re-engineering 4 Systems integration 4 Acquisition of information systems 4
ATA Data Model: Functional Areas • Derived through an affinity analysis between the structured decomposition of the industry functions/processes and the information/data used by those functions/processes
• Functional areas (business areas) were then used in the architecture of i Spec Spec 2200
• The functional areas are also consistent with a value chain analysis
