Access to Databases

5 Databo e-s and Data Sources in Chemi-stry 231 Table 5-2. Basic search tools of Boolean operators and truncation. 

The Boolean search operators are used to specify Logical relationships among the terms being searched. 

AMD two or more search terms liave to be in the same record (document) (e.g., acety lsalicylic AND headache) 

MOT excludes the following term (retrieves dociitYients with the first lenn and not the second) (e.g., acetylsalicylic MOT synthesis) however, this often has the danger that some important documents are not found  

Truncation allows one to search a tenn that is not exactly defined, such as singi.ilars, plurals,

The World Wide Web has transformed the way in which we obtain and analyze published information on proteins. What only a few years ago would take days or weeks and require the use of expensive computer workstations can now be achieved in a few minutes or hours using personal computers, both PCs and Macintosh, connected to the internet. The Web contains hundreds of sites of Interest to molecular biologists, many of which are listed in Pedro s BioMolecular Research Tools (http // www.fmi.ch/biology/research tools.html). Many sites provide free access to databases that make it very easy to obtain information on structurally related proteins, the amino acid sequences of homologous proteins, relevant literature references, medical information and metabolic pathways. This development has opened up new opportunities for even non-specialists to view and manipulate a structure of interest or to carry out amino-acid sequence comparisons, and one can now rapidly obtain an overview of a particular area of molecular biology. We shall here describe some Web sites that are of interest from a structural point of view. Updated links to these sites can be found in the Introduction to Protein Structure Web site (http // WWW.ProteinStructure.com/). 

Public access to databases maintained by the US. Environmental Protection Agency. Databases such as Air, Chemicals, Facility Information, Releases, Water Permits, Drinking Water Contaminant Occurrence, Maps, and more.

Databases. Sites such as Bath Information and Data Services (BIDS) and web of Science (WOS) provide access to abstracts of recent publications use these to find relevant literature for specific topics. Access is via the websites at http //www.bids.ac.uk/ or http //www.webofscience.com you will need a username and password - check with your department or library. In the case of BIDS, it provides access to databases covering subjects from science, engineering and medicine to economics, politics, education and the arts. Specific databases offered include ISI citation indexes EMBASE (international biomedical information) INSPEC (physics, electronic engineering and computing) international bibliography of the social sciences (IBSS) The Royal Society of Chemistry databases and education databases. See also Table 46.2. 

The recent development of pipelining tools such as Pipeline Pilot, Orange and Knime (see Box 23.3) has allowed QSAR developers to automate many predictive procedures. These tools give the user facile access to databases, stractures and data analysis methods. They allow complex QSAR procedures to be predefined and subsequently executed by non-experts so bringing predictive QSAR models directly to the medicinal chemist s work bench. 

Tire possibility of telemedicine , i.e. the provision of diagnosis and therapy at a distance by use of telecommunication systems, and the access to databases for medical knowledge plus the existence of, for example, automated analytical devices and robot surgeons (obviating tire physical presence of the surgeon in the operating theater) will facilitate the provision of the best expertise anywhere, anytime. 

This ability to specify database structures, through use of schemas, enables efficient and effective management of data resources. This is necessary for access control. The use of one or more subschemas generally simplifies access to databases. It may also provide for database security and integrity for authorized users of the DBMS. Since complex physical (computer) structures for data may be specified, independent of the logical structure of the situation that is perceived by DBMS users, it is thereby possible to improve the performance of an existing and operational database without altering the user interface to the database. This provides for simplicity in use of the DBMS. 

Today mHealth systems are a hot research topics for universities, the industry, and standard organizations where PBIs, telecommunication systems, data-processing systems, data privacy, and online health and on-the-go telemedicine services, databases, and access to databases are under constant development. Inasmuch as any wireless technology can be used to achieve mHealth, it is logical to isolate the concept in terms of services and technological approaches. Of course, mHealth is not limited only to humans the animal... 

Toxicology Data Network with data files on hazardous, carcinogenic, and other substances. Medical Literature Analysis and Retrieval System (MEDLARS) for access to databases from the Specialized Services department of the National Library of Medicine. 

BIMCO https //www.bimco.org/ (accessed September 14, 2010). Provides manbers with access to databases of international information on technical aspects of shipping, cargoes, safety, environmental issnes, and so on. 

Office of Coast Snrvey, US. National Ocean Service, National Oceanic and Atmospheric Administration (NOAA) http //www.nauticalcharts.noaa.gov/ (accessed September 14, 2010). Provides access to databases, charts, surveys, and other navigational products. 

Under the scope of glassmaking itself and of glass coloring, either bulk or surface (see Sec. VI.A), it is important to have access to databases of Raman spectra of glassmaking and glass-coloring compounds. The accessible databases are quite few they are available in paper form, not easy to handle for spectra comparison. Such databases are given in Refs. 26-28, 58, 59, 66, and 67. 

Novelty. It is desirable to steer the methods away from known ligands of the same system or closely related systems (or perhaps known molecules in general). Rapid access to databases such as those from Chemical Abstracts and Beilstein might allow this. Novelty is essential for patentability even more important, the more novel and different the strategies that are applied to a problem, the greater the likelihood of success. 

Materials Information Service, Design Council, 28 Haymarket, London, SWl Y 4SO, UK, Tel. (44) 071 839 80 00. Helpline, information service, access to databases. 

One of the characteristics of this system is that it allows multiple access to databases, indeed, currently more than 350 databases with a single logon. There is a multi-file environment, and the customer is benefited by the presence of only one means of accessing all of the different databases and their content. This imposes the additional burden on any new system that it be fully compatible with this mainframe environment and the appropriate input/output processors. 

DSHost uses the logical view to control access to databases, and to control the search and update procedures themselves. HViews may contain entries for mvdtiple chemical databases and multiple relational databases from multiple vendors. At one limit, an HView can define access to a single table in a single relational database if that is all that is required for an application. At the other limit, a complex HView can define mvdtiple, distributed chemical and relational databases, which are to be accessed at the same time. 

Mobile connectivity enables providers to use them in local and remote clinical settings (Mosa et al. 2012). It can provide access to databases on disease-diagnostic guidelines, dmg references, literature search, and medical education materials at the point of care, 24/7. It facilitates emergency rooms in remote locations to stay connected they can access online consultation, telemedicine, and obtain help in trouble shooting. With its graphic capability, it should soon be possible to provide online consultation in real time surgery.
