Abstract: Virtually, all businesses are moving to online services in which customers have easier access with more choices when buying products than other brick-and-mortar. Online stores have their own database so customers can search and compare one store to others to find the best choice. Because each database of online stores is different from others, integrating databases is a crucial factor for successful electronic commerce (E-commerce). The extensible Markup Language (XML) is one way to integrate such heterogeneous databases. This paper introduces one approach for integrating databases by applying the eXtensible Markup Language (XML) to the composite approach. Online movie store databases, for example, were used for demonstration purposes because it is initially difficult to understand how XML can be used for database integration. This XML subset is called a MovieStore Markup Language (MSML) which is used for integrating three different movie store databases. The result of this study found that the approach is very simple, quick, convenient, and saves costs for organizations and provides better services for customers.
