　　●Activity Based Costing (ABC) is an _(66)_ technique that allows an organization to determine the actual _(67)_ associated with each product and service produced by the organization without regard to the organizational structure. This chapter explains some of the uses and benefits of Activity Based Costing .We use IDEF0_(68)_modeling in conjunction with ABC to enable more effective business_(69)_design decisions. 
　　In order to achieve the major goals of business process improvement, process simplification and improvement, FAA manages need to fully understand the cost, time and quality of activities performed by employees or machines throughout an entire organization. ABC methodsenable_(70)_ to cost out measurements to business simplification and process improvement.

　　●One of the difficulties in building an SQL-like query lange for the Web is the absence of a database_(71)_for this huge, heterogeneous repository of information. However, if we are interested in HTML documents only, we can construct a virtual schema from the implicit structure of these files. Thus, at the highest level of _(72)_,every such document is identified by its Uniform Resource Locator(URL), has a_(73)_ and atext. Als, Wed servers provide som additional information sucn as the type, length, and the last modification date of a document. So, for data mining purposes, we can consider the ste of all HTML documents as arelation: 
　　Documen (url, title, text, type, length, modify ) 
Where all the _(74)_ are character strings. In this framework, anindividual document is identified with a_(75)_ in this relation. Of course, if some optional information is missing from the HTML document, the associate fields will de left blank, but this is not uncommon in any database.
