Online databases are popular and widely used in everywhere. They are very useful for information professional, students, teacher, researchers and other information seekers. Online databases are mainly used in libraries and includes over millions of contents, articles, journal, images and other primary sources. Users also get the knowledge of the online databases features and they can search their information need from online databases effectively. Using of online databases people can save time, money, space and can also get the greater efficiency. Searchers can get qualitatively various kinds of results and easier to access the desire information. Online database services also offer term searching of fields, controlled vocabulary, keywords, etc. User can use the search functions (Boolean operator), word searching and search levels to search the required data simply and quickly. Online databases are well organized database so can be quickly select to find the desired information.
And also increasing the number of online databases, it is important for user need to select the right databases to meet their needs of information. Online databases have been used for searching many years ago and as they have gradually improved and become an acceptable tool for novice to expert users in various kinds of professional areas. In this paper, we would like to evaluate the three different popular databases. They are JSTOR (Journal Storage), ScienceDirect Online and Web of Science. Databases are also evaluated according to the three criteria: General, Search Functions & Capabilities, and Display & Output. And also compare these three of databases and pointed the distinct features of them.
2 Overview of the databases
Before we are going to evaluate the databases, we would like to introduce the general description and some features found in each database.
2.1 JSTOR (Journal Storage)
JSTOR (short for Journal Storage) is a United States-based online system for archiving academic journals, founded in 1995. It provides full-text searches of digitized back issues of several hundred well-known journals, dating back to 1665 in the case of the Philosophical Transactions of the Royal Society.(Wikipedia). JSTOR is one of the world's trusted sources for academic content. It provides more than a thousand academic journals and over one million images, letters, and other primary sources.
It uses high resolution images to display and print definite replications of the pages that make the complete published record of the journals in its archive. And also includes over thousand leading academic journals across art and humanities, economics and business, science, and social sciences. JSTOR is a full-text documents and collection of digitally achieved, scholarly articles. All articles in JSTOR are displayed in the PDF file format (Adobe Acrobat Reader software required to view).
2.2 ScienceDirect Online
ScienceDirect Online is a leading full-text scientific database offering journal articles and book chapters from more than 2,500 peer-reviewed journals and more than 11,000 books. There are currently more than 9.5 million articles/chapters, a content base that is growing at a rate of almost 0.5 million additions per year. Users can access full-text articles as well as abstract records from all fields of science. Most journal articles become available immediately after peer review and before the printed versions are issued. Additionally, they gain online access to multimedia features not available in print journals, such as video, audio and spreadsheet files. (About ScienceDirect)
ScienceDirect Online offered three different levels of searching methods (such as Quick Search, Basic Search and Advanced Search). There are no full search features of ScienceDirect Online for guest users. But, Guest users could search by using Quick Search. In order to search all available documents, journals, or books, Basic Search has provided pre-defined fields. And, Users could limit their search with document type, publication type, date period and subjects. Users can build complex search methods by using Boolean operators, proximity operators and truncations in the Advanced Search.
2.3 Web of Science
Web of Science offers access to world's leading citation databases and online academic citation index. It provides for authoritative, multidisciplinary with current journal, in-depth exploration of specialized fields and data in the sciences, social sciences, arts, and humanities coverage from the year 1900 to the present. And offer search comprehensive global and regional coverage. Moreover, can discover research ideas to detect emerging trends for successful research and grant acquisition with significant cited records. And also can see conference proceedings influence work in related disciplines and can be selectively obtained.
Web of Science provides seven databases that contain gathered information from thousands of books, journals, series, reports, conferences, and more. The seven databases of Web of Science are: Science Citation Index Expanded, Social Sciences Citation Index, Arts & Humanities Citation Index, Conference Proceedings Citation Index - Science, Conference Proceedings Citation Index - Social Sciences & Humanities, Index Chemicus, CurrentChemical Reactions.

Comparisons in the use of General Features
Most of the interface designs of databases are not quite different. In out selected databases, JSTOR and ScienceDirect Online databases are similar in their basic interface and user needs (such as textual interface and search history facility). But, Web of Science starts complex interface design (such as search using Boolean operators, etc.). All of three databases mainly covered on sciences, technology, art and humanities. They also generally retrieved most of the journal's articles and journal's issues. And the three databases offered updated documents and old documents. Especially, ScienceDirect Online database offered even first volume of each journal. ScienceDirect Online and Web of Science database have continuous update (such weekly and monthly). But JSTOR database makes update per year.

After evaluating the 3 databases, all of the above databases are mainly cover on sciences, technology, social science and humanities. But there are some different information depends on different database. Such Web of Science database also offer conference proceedings citation Index-science and multidisciplinary. This is very important for successful research. And JSTOR database can available oldest document from 1655 to 2010. This is the strength of JSTOR database than other databases. Time coverage is also important. In the ScienceDirect Online database, the subject areas can cover first volume of each journal and it also offers continuously update function.
