For example, a price comparison system needs to extract information, such as product names, prices, purchase methods, etc, from some related e-commerce sites. Other examples are to extract news from news providers and to collect categories of publishers. In our past projects, we develop a browser oriented data extraction system. And, defined a data extraction language, named BODED (Browser Oriented Data Extraction Description), and designed to solve the problem of data extraction a system for it whose technique has been transferred to industry. However, the way to manage the extracted data for data management is the next very important research topic. The basic applications include: data storing, data query, Web site reengineering, and Web site integration. BODE is a strong tools to extract Web data. In order to handle the extracted data, we introduce a data model and develop a generic method to store those extracted data to database properly. Base on BODE and BODELET, we define a description language to describe the structure and relation of the extracted data. Hence, we developed a software component, named BODELETDB. This component can automatically store the extracted data to database directly and clearly.
