The global network is changing the way every business works. In particular, new networked applications will affect the way in which organizations work with documents. Document management solutions help organizations run smarter and maximize business performance. This document management software was created to help people control and organize all of their work-related documents regardless of whether they exist as an email, a paper copy, a word processing document, an image, or a spreadsheet.

The increasing usage of personal computers and Internet in organizations made it possible to create, edit and share various documents between different employees of the organization. However, document management becomes very troublesome, especially if several employees can contribute changes to a singe document: it is very hard to locate latest document version, or determine which changes to the document were made by which employee. Document management systems are aimed to solve these problems. However these systems often are highly specialized and very costly to implement, or they are general-purpose and hard to customize and apply to organization business domain. Inabilities to customize often arise from strict and inflexible metadata model, used in document management system. The aim of this work is propose abstract document metadata definition and processing model, based on XML data definition language and concept of XML data processing pipeline. The proposed model is general-purpose and highly flexible at the same time, enabling to apply model to any business domain and customize it to reflect any features specific to this domain.

Document management systems allow organizations to have greater control over the lifecycle of documents from creation through review, storage, retrieval and dissemination all the way to their destruction. Document management provides greater efficiencies in the ability to classify and reuse information. This document deals with issues of storage and retrieval processes of text documents in document management systems. Main focus is made on choosing an effective document format, means and methods for storing and retrieving documents. The paper suggests using XML as the base document format and relational database management system as backend storage of the document management system. A new modification of the standard Edge method for storing and retrieving XML documents from relational database management systems is introduced and the results of its performance experiment are presented. The experiment proves the performance superiority of the modified Edge method over its standard analogue.

Šalia tradicinių informacijos srautų vis didesnę reikšmę ir vietą užima elektroninė informacija, tačiau informacijos amžiaus paradoksas yra tas, kad didesnė dalis elektroninės informacijos yra sunkiau prieinama nei anksčiau sukurtoji arba neprieinama visiškai. Elektroninė informacija kuriama, valdoma, perduodama ir saugoma naudojant dinamiškas, greitai kintančias informacinių technologijų priemones. Dėl greito technologijų senėjimo informacija, sukurta jas naudojant, prarandama arba tampa sunkiai prieinama ir dėl to negalima naudoti. Informacijos elektroninėje aplinkoje atsiradimas ir sklaida neišvengiamai keičia požiūrius ir sampratas. Atsiranda būtinybė peržiūrėti ir pateikti naujus archyvų veiklos organizavimo principus bei metodus. Dokumentų saugojimas paprastai yra apibrėžiamas kaip archyvo veiklos uždavinys, įgyvendinamas per archyvo vykdomas funkcijas, kurių tikslas – apsaugoti dokumentus nuo sugadinimo, sunykimo ar praradimo, sudaryti prieigos prie saugomų dokumentų galimybes, kad būtų tenkinami visuomenės socialiniai, teisiniai, kultūriniai, informaciniai poreikiai, taip pat išsaugoti dokumentus ateities kartoms kaip kolektyvinės atminties šaltinius. Dėl išaugusio informacinių technologijų naudojimo institucijų bei ūkio subjektų veikloje vis daugiau dokumentų sudaroma tik skaitmeniniame formate. Elektroninis dokumentas nuo tradicinio dokumento skiriasi tuo, kad jis yra sukurtas, laikomas, naudojamas ir saugojamas skaitmeniniame formate, tačiau, nepriklausomai nuo...

Documentary heritage in the form of records or documents (archives) is an essential part of this memory. Over the last decade, the social role of local cultural institutions of all kinds has changed. A shift from the use of information on traditional paper-based carriers to electronic formats has taken place. The implementation of technology has brought about the modernisation of basic work processes and widened the range of services and channels of access. Memory institutions such as archives are adjusting themselves to the digital age. Originally, any computer data were considered as something internal — the final data output was always on paper. However, the development of computer networks have resulted in that in most cases it is much more convenient to distribute electronic documents than printed ones. And the improvements in electronic display technologies mean that in most cases it is possible to view documents on screen instead of printing them . However, using electronic documents instead of paper ones have created the problem of multiple incompatible file formats. Preservation and access to electronic records in electronic form is an important and difficult issue. Archival institutions have a distinctive mission − to give guidance on these problems to the creators of electronic records, to receive transfers of the electronic records, and to preserve and give access to...
