This work presents a proposal to utilize database technology for storing and managing learning objects in a database federation (distributed database). The evolution of e-learning has brought the focus over the productivity to make and to manage the content of learning modules, which today comprises videos, audio, among other related data, besides the text data. Instructors normally store this material without worry about sharing. As a member of PGL - Partnership in Global Learning - a virtual organization for research, development and dissemination of learning through new technologies - TecBD - the PUC-Rio`s Database Laboratory is researching the use of database approach for managing learning objects stored on interconnected sites composing a heterogeneous distributed database environment. This work intends: 1) using market ready DB products; 2) adopting the actual standards for defining of learning objects; 3) considering learning objects stored on separated and autonomous sites; 4) to develop an application (a study case) with these learning objects. The learning object`s model establishes a structure for composing learning objects by linking atomic elements and also linking composed elements. Different approaches as Web Services, Java/Servlets and Web Application Servers were considered for the geographically distributed problem. A study case was build using the product IBM DB2 with the provided extenders for audio, video, image, XML data and the Federated System Support. The web browser`s explore of the stored data was build using the IBM Net.Data software. Although not exclusive, it provided an easy way to perform this task and also enabled an easy integration with IBM DB2 and its extenders.
