Enhanced Metadata Utility (EMU)

  • EMU is an Excel-based utility for the exchange of information with popular modelling tools and formats: CA ERwin, Sybase PowerDesigner and xml Schema
  • Metadata can be extracted into Excel from data models, manipulated in user-friendly spreadsheets and exported back to the data modelling tool.
  • Artefacts supported from ERwin included Entities, Tables, Views, Relationships, Domains, Definitions, Datatypes, User Defined Properties and more.
  • Supported from PowerDesigner include items such as Tables, Views, Mappings, Comments, Datatypes, MappedTo transformation rules.
  • xml Schema capabilities include abilities to extract elements, attributes complex types, xpath information, data constraints etc.
  • Metadata interchange is all governed by Excel based 'templates'. These are customised to adapt to clients' requirements.
  • Simple definition template available for management of business definitions outside of ERwin and PowerDesigner. This is the most common usage since business analysts find it much more convenient to maintain lists of definitions in Excel rather than a data tool.
  • Other templates are available for managed more advanced features of data models, such as Domains or Valid Values.
