This proposal is broken into four projects. The first project is the implementation of a quick retrieval system for laser discs that will allow users to rapidly access large amounts of data via internal computer controlled hashing tables either stored on the laser disc or maintained via maintenance software on other storage media. The second project consists of a library of subroutines to access and maintain the database indexing system for people who wish to customize their software. The third project is the development of software to allow noncomputer users to generate courses via the use of indexes through the data. This section will allow teachers to perform the following functions: customize display screens, set up Instructional text, mark answer storage for later retrieval and customize branching indexes through the information database. The last section deals with the use by students. These programs will store answers to questions automatically, allow students to migrate through the course and allow them to retrieve information from within the database. The development of code shall be performed in the Ada programming language.Anticipated Results and
Potential Commercial Applications: With the current developments in laser disc information systems, a need is developing to be able to link multiple sets of laser discs together. Currently there is no standard method to perform this function. We intend to develop a method that will allow linking and allow users to customize the information to the way they wish to view it. The next benefit is to agencies with in the government that are currently beginning to develop laser-based information systems by giving them the ability to link together the information from different areas and allow them to have their information stored in a fast retrieval method. Current possible users are the Defense Mapping Agency System.Key Words: Ada, Hashing, Educational Software, laser discs, Databases, Indexing, Real-time, ToolsTopic 8.9: Development of Quick-retrieval Indexing for Large-storage Information for use by Disabled Individuals
