Digital Reminder: Real-World-Oriented Database System

Digital Reminder: Real-World-Oriented Database System

Digital Reminder is a system which manages a person’s view images based on gaze detection. A real-world-oriented database that consists of one’s view is constructed by one’s implicit behavior of watching objects. Digital Reminder provides a user with WYSIWYR(what-you-see-is-what-you-retrieve-)based interaction for view image retrieval. WYSIWYR is a new framework in information retrieval. In ret...

Database Design with Real-World Structures

The simplicity of the relational model types affects Information Systems design. In this paper, we discuss another approach, where the Information System designers would be able to depict the real world in a database model directly. This model provides more powerful and composite data types, as those of the real world. However, more powerful models need query and manipulation languages that can...

Object-Oriented Analysis in the Real World

Theory and Practice There is theory, and there is practice. There is the plan, and there is its execution. This paper concerns itself with the practice and execution of using Shlaer-Mellor objectoriented analysis (OOA) [1, 2] on real-time control systems. The task of the project manager is to make the theory and the plan work together in the context of a given organization, project, and enginee...
