Data base management system, search

Algorithm development in the areas of computer editing, data base management, sorting, computer-based composition, and text searching have been critical to the overall development of computer-based primary and secondary publications systems and text search services. Results of these developments are illustrated in the computer-based information system used at Chemical Abstracts Service (CAS) [ 1]. Lynch [2J describes principles and techniques for the computer-based information services and... 

The mentioned data management systems are only first steps toward comprehensive lipid databases and global lipid networks. An example for such a data bank is LIPIDMAPS (http //www.lipidmaps.org), which covers structures and annotations of biologically relevant lipids (43). The structures originate from the core laboratories of the LIPIDMAPS consortium and their partners. In this database, users can search the LIPID MAPS proteome database using either text-based or structure-based search options. In addition to LIPIDMAPS, other databases in Europe (http //www.lipidomics.net) and Japan (http //www.lipidbank.jp) have been initiated. 

Data management in terms of archiving and retrieving of records is an essential feature in the modern laboratory there are many issues with paper systems, which are alleviated if not removed altogether through the use of computerized data. The facility to search and select data is far more rapid and reliable than a paper-based system. With the increase in regulatory scrutiny of electronic records, it may ultimately become a requirement that data be available in electronic form to support submissions. Other advantages of a... 

The proposed system has three functions (1) accuracy evaluation, (2) accuracy data accumulation, and (3) search and reuse of accuracy data. The objective of the study shown in this section is to build a method for identifying knowledge, knowhow and techniques in the field based on the data managed by the developed system and evaluated by the three dimensional measured data in the ship construction process. The overview of the whole system is shown in Fig. 23.10. All types of data are stored in the database and, as well, the metadata is assigned to the data. Any data stored in the system can be reachable efficiently thanks to the metadata.

There are, however, important implications for host-based software as well. With a consistent data model in hand, it is possible to define a more coherent search system. Such a system makes it possible to mask many of the idiosyncrasies of the component DBMSs by orchestrating complex searches over multiple, distributed databases behind the scenes , so the user does not need to understand what data are being searched where. In the next section, we briefiy discuss some recent results obtained by adopting a unified approach for searching and updating data in combined chemical and relational database management systems.

Chemical data base systems, and especially the DARC Structure Management System (DARC-SMS), have from the beginning offered sophisticated capabilities for chemical structure registration and structure, or substructure, or generic substructure search.
