Chapter 3 DATABASE/DBMS Solution to the computing problem Applications of your emerging in Database Before defining Digital Libraries, we introduce several fundamental assumptions: · The digital libraries are not a bounded, uniform collection of information. · There will be increasing diversity of information and service providers.

· There is more than just searching in digital libraries. Especially we should notice the last point. the main activities of users can be classified into five categories: locating and selecting among relevant sources, retrieving information from them, interpreting what was retrieved, managing the filtered-out information locally, and sharing results with others.

These activities are not necessarily sequential, but are repeated and interleaved. Users can move freely in the circle to get their work done. In general, users will be involved in multiple tasks at the same time. They willneed to move back and forth among these tasks and among the five areas of activity.

They need to find, analyze, and understand information of varying genres. They need to re-organize the information to use it in multiple contexts, and to manipulate it in collaboration with colleagues of different backgrounds and focus of interest. The main activities of digital library users. There is no single definition for Digital Libraries. The definition evolves as research progresses and we learn more about digital libraries. Some of the current definitions are:

· Digital libraries are systems that combine the machinery of digital computing, storage and communication, the content, and software needed to reproduce, emulate, and extend the services of collecting, cataloging, finding and disseminating information offered by traditional libraries based on paper and other materials.

A full service digital library must not only fulfill all essential services provided by traditional libraries but also make good use of the advantages of digital technology. · Digital libraries are viewed as systems providing a community of users with coherent access to a large, organized repository of information and knowledge. This organization of information is characterized by the absence of prior detailed knowledge of the uses of the information.

The ability of the user to access, reorganize, and utilize this repository is enriched by the capabilities of digital technologies. · The concept of a digital library is not merely equivalent to a digitized collection with information management tools. It is rather an environment to bring together collections, services, and people in support of the full life cycle of creation, dissemination, use, andpreservation of data, information, and knowledge.

From the definitions above, it can be concluded that researchers have stretched the definition of digital libraries. More people are recognizing that digital library is not a topic only in discover,retrieve,interpret,manage,share.

Digital libraries are libraries extended and enhanced through digital technology. Important aspects of a library that may be extended and enhanced include: · the collection of the library· the organization and management of the collections · access to library items and the processing of the information contained in the items· the communication of information about the items.

The purposes of digital libraries are: · to speed up the systematic development of the means to collect, store, and organize information and knowledge in digital form, and of digital library collections,· to promote the economical and efficient delivery of information to all parts of society,· to encourage co-operative efforts which leverage the considerable investment in researchresources, computing and communications network,· to strengthen communication and collaboration between and among the research, business, government and educational communities,· to contribute to the lifelong learning opportunities of all people..

Digital libraries distribute a rich and coherentset of information services (including selection, organization, access, distribution, and persistence) to users reliably and economically.

These services are enabled by a suite of tools that operates on objects consisting of content packages, related metadata, service methods, and means of management. with different technologies, and hence each constitutes a digital library. However we should integrate virtually separate libraries into a single one. Chapter 4 Summary of findings, Conclusions and Recommendation Conclusions: Digitization has opened up new audiences and services for libraries, and it needs to be integrated into the plans and policies of any institution to maximize its effectiveness.

Digitization is a complex process with many crucial dependencies between different stages over time. Utilizing a holistic life-cycle approach for digitization initiatives will help develop sustainable and successful project. It is hoped that the approach of the issues outlined, the software mentioned in this paper and the references to more detailed source and past project will contribute to the future success of initiating digitization of library resources. Id also find out that definitions for digital libraries has somehow remain and havent changed.

The common consensus is that they provide their users with a coherent view of heterogeneous autonomously managed resources. There are a lot of research issues waiting for resolutionA commonly accepted architecture of digital library is based on digital objects and handle system and common repository access interface. It achieve to explain areas such as description of object and repositories, user interface and interoperability. But digital libraries are much complicated systems. It is basically international. It is involved in many communities, including social, legal.

and political communities. Extreme effort are necessary for solutions to safeguarding digital content and users to provide them convenient services at the same time. There is still a long way for it to achieve maturity and become commercial products. Bibliography:
