Database Design for Web-Based Product Catalog

A Web-based product catalog is an online product database that requires easy access from anywhere in the world and uses the most efficient method for information retrieval. The database should support all products no matter what attributes the product has. Many large businesses have been unsuccessful in their attempts to create a product database that enables fast, efficient access across the Web. As there are many complex issues involved with the storage of product information, many companies settle for poorly designed databases as a tradeoff to becoming Web compatible faster.

This paper explores database-driven e-commerce product catalogs and the issues that inhibit their creation. The design put forward in this paper also allows for storage of product attributes that have no structure, like media objects. Media objects are becoming an important feature to product catalogs, especially those on the Internet. Another important feature supported by the proposed database is the ability to be combined with Multilanguage support features. These features allow every piece of product information to be translated into any supported language.

 

Particle Swarm Optimization Algorithm for A Model Of Optimally Scheduling Web Advertising Resources

A model of scheduling web advertising resources for maximizing advertising effect function is proposed, according to the properties of web advertising.

A quadratic punishing item that separates the advertising impressions is added to the Langheinrich linear model in order to better exert advertising efficacy with the optimized solution. An improved particle swarm optimization (PSO) algorithm is designed to handle the constraint efficiently, considered the properties of PSO algorithm and constraint of models. Simulation result shows the validity of this algorithm.

Data is not information, Information is not knowledge, Knowledge is not understanding, Understanding is not wisdom. Cliff Stoll & Gary Schubert

Projections are bullshit. They're just guesses. Wait until the real thing happens and then when it happens, then you can make the decision. Make decisions when you have a lot of information to make the decision. Not when you have to guess about what the decision is going to be or use data that doesn't exist yet. Jason Fried, Keynote Speech, SXSW 2006
