Visual Basic 6.0

We design a small supermarket purchase-sell-stock management system. The system uses Microsoft Visual Basic 6.0 and Microsoft Access 2003 as development tools, uses the object-oriented program design method, data model is housed in a class, which improves the data safety in operation; in addition, the system uses the multilayer structure design patterns, which has powerful advantage in module independence and code reuse. The system can satisfy daily job requirement for a small supermarket.

Security Levels

In this chapter, we extend the multi-level secure (MLS) data model to include nonkey related cover stories so that key attributes can have different values at different security levels. MLS data models require the classification of data and users into multiple security levels. In MLS systems, cover stories allow information provided to users at lower security levels to differ from information provided to users at higher security levels. Previous versions of the MLS model did not permit cover stories for key attributes because the key is used to relate the various cover stories for a particular entity. We present the necessary model changes and modifications to the relational algebra, which are required to implement cover stories for keys. We demonstrate the improvements made by these changes, illustrate the increased expressiveness of the model, and determine the soundness of a database, based on the described concepts.

Dance videos are interesting and semantics-intensive. At the same time, they are complex type of videos, when compared to all other types such as sports, news and movie videos. In fact, dance video is the one which is less explored by the researchers across the globe. This paper presents a dance video data model to represent the semantics of the dance videos with different granularity levels, identified by the components of the accompanying song. Secondly, the paper proposes a multi-level index structure to efficiently handle containment, temporal, spatial and spatiotemporal query types. Moreover, the index structure has been designed to consider the queries with different levels of constraints. Finally, the paper presents the experimental results depicting the performance of different types of dance video queries.

Server Architecture

<p>A general software architecture for large and medium size information systems is presented. The architecture is a multi-level client-server architecture, where all dependencies on hardware and software platform are encapsulated into modules. The architecture provides a skeleton around which to grow an information system and is independent of the actual data model, functionality and user interface of the system. It supports division of labour during development, and it supports maintenance and portability of the resulting system. In all these respects, the architecture is superiar to the architecture obtained when using fourth generation languages.</p><p>The architecture has been successfully used in several large projects during the last 6 years and practical experience shows that it provides a reusable starting point for future development projects.</p>
