Graphic Interface for Attribute-Based Data Language Queries from a Personal Computer to the Multi-Lingual, Multi-Model, Multi-Backend Database System over an Ethernet Network
Abstract
This research is aimed at taking one step closer to the goal of the paperless ship. This thesis examined the feasibility of providing a visual interface to allow queries from a front end Personal Computer (PC) using the Attribute-Based Data Language (ABDL) to a Multi-lingual, Multi-model, Multi- backend mini-computer . Providing an improved Human-Machine Interface for the system will greatly increase its usability. A prototype was implemented in the Graphics LAnguage for Database (GLAD) on a Zenith 248 as the front end connected to a ISI mini-computer running the Multi-Lingual, Multi-Model, Multi-Backend Database System (MBDS), a backend of the future. The Zenith 248 was chosen as the front end because of the large quantity of these computers throughout the Navy. GLAD was used because it is a graphics object-oriented environment for databases that gives the user access to both data manipulation and program development through visual interaction. This creates a user friendly windowing environment both for development and for operational applications. Looking towards the future, MBDS is the perfect backend as it is the latest in Database management systems. This thesis provided an extension to GLAD to demonstrate the ability to send Attribute-Based Data Language to Multi-Backend Database System. (kr)
