in the early and mid-1 990s, CAS developed SciFinder and SciFinder Sc ho lar to address the needs of professional chemists and other scientists. SciFinder was developed to allow more intelligence in data access, such as smart structure searching, research topic exploration, advanced author searching, and powerful refine and analysi.s capabilities including categorize and panorama . 

In the mid and late 1990s CAS developed the ChemPort module as a linked gateway to primary literature. The CAS online delivery clients arc able to move into CbemPort to display primaiy literature by presenting stored or dynamically generated URLs to ChemPort. Conversely, ChemPort will link a user to SciFinder to provide access to the CAS databases.

While professional awareness has increased, there are still hindrances to universal access in the workplace. Today almost all companies have access to the Internet, but company policy may limit usage during business hours or on company equipment Also, many countries still face prohibitive online access charges, although free market competition will take care of that in time, and Canada s no-charge policy may well be the wave of the future ... 

Access to CAS databases is only possible on computers on which the SciFinder software has been installed. Tt is directly available at CAS, computational seiwice centers, or library seiwices with online access. The database is not free of charge access can be obtained only via these services. After the licensed software has been installed and online access is obtained, the program tan be started. 

Many database producers provide online access to thek databases or distribute thek databases on compact disc read-only-memory (CD-ROM) and so are also considered vendors or producer/vendors. Whereas numerical growth in vendors is indicated (Fig. 1), the success of the database industry is largely a result of the transition of the information industry from paper-based to computer-based services (see Computer technology Informiation RETRIEVAL, Inforitation STORAGE MATERIALS). Thus industry growth can also be measured in terms of the increase in use of computer-readable databases as exemplified by the number of searches.

It can be difficult if not impossible to find the domain structure of a protein of interest from the primary literature. The sequence may contain many common domains, but these are usually not apparent from searches of literature. Articles defining new domains may include the protein, but only in an alignment figure, which are not searchable. Perhaps, with the advent of online access to articles, the full text including figures may become searchable. Fortunately there have been several attempts to make this hidden information available in away that can be easily searched. These resources, called domain family databases, are exemplified by Prosite, Pfam, Prints, and SMART. These databases gather information from the literature about common domains and make it searchable in a variety of ways. They usually allow a researcher to look at the domain organization of proteins in the sequence database that have been precalculated and also provide a way to search new sequences...

The PIR Protein Sequence Database (Barker et al., 2001 Wu et al., 2002) developed at the National Biomedical Research Foundation (NBRF) has been maintained by PIR-International Protein Sequence Database (PSD), which is the largest publicly distributed and freely available protein sequence database. The consortium includes PIR at the NBRF, MIPS, and JIPID. PIR-International provides online access at http //pir.georgetown.edu to numerous sequence and auxiliary databases. These include PSD (annotated and classified protein sequences), PATCHX (sequences not yet in PSD), ARCHIVE (sequences as originally reported...

The PubMed site (http //www.ncbi.nlm.nih.gov/Entrez) is developed by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine (NLM), located at the National Institutes of Health (NIH). It has been developed in conjunction with publishers of biomedical literature as a search tool for accessing literature citations and linking to full-text journals at web sites of participating publishers. This site allows online access to the Medline database containing bibliographic citations and abstracts from journals dating back to 1966. 

Recent advances in chemoinformatics have greatly enhanced the utility of these resources and many are now accessible via the Internet.28 CHEMnet-BASE (www.chemnetbase.com) provides online access to a variety of databases including the Dictionary of Natural Products and the Dictionary of Marine Natural Products, although full access through CHEMnetBASE requires a subscription. The Chemical Structure Lookup Service (http //cactus.nci.-nih.gov/lookup) is an open access database and incorporates information from more than 80 databases on over 27 million structures. PubChem (http //pub-chem.ncbi.nlm.nih.gov/) is another open access database that also links bioassay data to each structure. Measures such as the US National Institutes of Health (NIH) Public Access Policy Mandate should increase the amount of openly accessible information available on the Internet and facilitate dissemination of information.

With the development of the Internet, online access to scientific computing resources became possible. Diverse web technologies are used in this research to separately implement the one- and three-dimensional MRTM simulation systems. The web technologies used in the one-dimensional simulation system are discussed in Zeng et al. (2002). This section covers details of web technologies, especially Java technologies, that are used in the three-dimensional simulation system. The major goals and system requirements of the two simulation systems are also compared.
