Retrieval, information and

In homologous recombination, an intact homologous duplex is used to retrieve information and fix the duplex with strand breaks. The three basic steps in homologous recombination... 

Data banks are information retrieval systems, providing the user on request with information on certain subjects, or with problems of a certain kind. Thus, the programs of the previous chapter may be categorized as data banks. Requests may be in natiual language ( Why did Nero play the violin ) or in some kind of code ( C22—I—A1 D23 ), they may involve aspects e.g. in a computerized libreiry, see "The Techniques Used to Retrieve Information and Data from the Literature in this volume) they can be used in a batch mode or interactively, alone or imbedded in some regular course. Only the latter aspect is of interest in this article. 

The ROSDAL (Representation of Organic Structures Description Arranged Linearly) syntax was developed by S. Welford, J. Barnard, and M.F. Lynch in 1985 for the Beilstein Institute. This line notation was intended to transmit structural information between the user and the Beilstein DIALOG system (Beilstein-Ohlme) during database retrieval queries and structure displays. This exchange of structure information by the ROSDAL ASCII character string is very fast. 

Both database sources contain evaluated data on millions of compounds, and allow the retrieval of bibliographic information and of structures. 

BRS/Morning Search is available only in Europe and retrieves information from the BRS Online Service databank. BRS/Colleague provides access to the BRS Online Service databank, but it is a menu-driven on-line service designed for use by health professionals with or without on-line search experience...

Patent tides are usually short, and sometimes extremely uninformative. Patents in the latter category include tides such as "Chemical Product" and "Process." Derwent rewrites tides to make them more informative, and IFI/Plenum augments many tides. Words included in patent tides normally are highly relevant, and tide terms are thus usefiil in providing focused, though incomplete, retrieval. 

Present-day nomenclature is partly the result of the conflict and interplay of two functions the need to communicate in speech and on the printed page on the one hand, and the need for archival storage of information and its efficient, reliable retrieval. The former function came first, and laid the basis for the nomenclature most commonly used even today, and gave birth to a wealth of trivial names (i.e. names that give little or no information on structure). These were often coined on the basis of the origin of the substance, as in the case of collidine, obtained from distillation of bones in glue factories, or were derived from a special characteristic, as in the case of skatole, which has a fecal odor. Such names are short and generally euphonious, but they must be memorized they cannot be deduced from the structure.

The RMDB consists of two mayor sections computer data storage and retrieval system, and backup microfilm data bank file. The computer data storage and retrieval system is used for die standard reliability and maintainability data listing, special calculations, and searches. This data bank system has been established to facilitate remote terminal access compatible with the GIDEP remote terminal programs. The microfilm data bank file is used for storage and distribution of supplier s documents, failure analysis curves, description of methods used in the collection of the data, and additional background information too extensive to include in the computer data bank. 

Data files on the THERdbASE CD are 1990 Bureau of Census Population Information, California Adult Activity Pattern Study (1987-88), AT T-sponsored National Activity Pattern Study (1985), Chemical Agents from Sources, Chemical Agent Properties, Air Exchange Rates, Information from EPA s TEAM (Total Exposure Assessment Methodology) Studies, Information from EPA s NOPES (NonOccupational Pesticides Exposure Study) Studies, Information from EPA s AIRS (Aerometric Information Retrieval System), and Human Physiological Parameters. 

Each entry must be dated. This not only makes it easier to retrieve information in the future, but it makes it possible to reconstruct the chronology of work performed and correlate it with other activities. In an analytical laboratory where a customer alleged that a sodium thiosulfate reagent solution used in a titration had been improperly prepared, the date reference made it possible one year later to tie the sample in question to a specific batch of reagent. This careful record prevented a threatened lawsuit.

In a further case relating to the structure of data stored on or in a record carrier used in a picture retrieval system, the European Patent Office s Boards of Appeal have considered the issue of patentability of a data structure [22]. Initially the patent application had been rejected on the grounds that the presentation of data was excluded from patentability (see above). However, in accepting an appeal filed by the patent applicant, the Board pointed out that there was a difference between the functional data, which controlled the technical working of the system, and the cognitive information, which represented the picture that could be retrieved and displayed. The Board stated that functional data relates to data that control the technical operation of the system. These data do not relate to the presentation of information, and thus data structures containing this information should be patentable. On the other hand, the cognitive information relates to the picture that could be retrieved and displayed.
