An efficient management system for large digital object collections

Includes abstract.Includes bibliographical references (leaves 87-91)Cultures evolve continuously, and it is therefore vital to track and record these changes, and most importantly of all, manage the resulting huge mass of data such as images, video clips, audio recordings and documents. This thesis examines the design of a Web-based solution, hereafter referred to as the Information Management System (IMS), to handle the efficient, accurate and secure management of a large number of objects

Rapid software prototyping using visual language techniques

Rapid prototyping of domain-specific software requires a systematic software development methodology and userfriendly tools. Being both executable and easy to use, visual languages and their automatic generation mechanisms are highly suitable for software prototyping. This paper presents a software prototyping methodology based on the visual language generation technology, that allows visual prototyping languages to be specified and generated using an expressive graph grammar formalism. Executable prototypes and their verification and code generation are made possible by syntax-directed computations. The paper demonstrates this methodology through a prototyping example built on our current implementation.
