DATA TYPES STARS systems consists of three basic groups of data types Authoring Documents, Model Document, and Workorder Documents. Authoring Documents Digital Documents, IETM Sections, and Annotations Model Document CAD and Hierarchal Model Workorder Document ( transient, archivable ) Workorder, Sticky Explain between transient achievable.

Storage Medium Lotus Notes Database Document based Database Stores Authoring Documents, Workorder Documents, Model Documents Flat File CAD model Perhaps the most import feature of Notes is its replication engine. This allows data from a Notes database to be shared over a Local Area Networks (LANs) and Wide Area Networks (WANs), using a wide range of protocols. Users may also share data using plain old ordinary asynchronous dial. up. Notes automatically handles all facets of the communication and replication of data between the various sites. It also recognizes and flags any documents that contain replication errors. Unstructured data (not rows and columns) Document based Complex documents i.e. integrate word processing, spreadsheet and other data into a single document Shared over a wide area Multiple key values Requires a short development time Require full text indexing

Storage Space Requirement Size of IETM Average of 80 MB Size of Model Each additional detail level (tree depth) yield exponentially larger size. Size of Workorder Document Transient: very small Archived: very large due to number of Workorder Documents

Storage Space Requirement Server Stores everything PEDD’s Fix Disk ( Wearable computer ) Workorder Document IETM and Model sections PEDD’s RAM Visual Display, Speech Workorder Document and IETM information

Database features Lotus Notes Database Identification Model Document, Authoring Documents and Workorder Documents are independent of each other but linked by part number (IETM ID). Security STARS teams focusing on a single point of interface for the system and data through Lotus Database. Security Information will be store within the Database. Introduce the Global Resource Handling. Stephen will talk more in depth on authentication.
