Computational data management

Today there are alternatives to the after-the-fact method of inhibitor monitoring and control, with the advent of automatic, semicontinuous, and continuous control methods that employ tagging and tracing and similar techniques. These newer methods can often be linked to computer data management programs. 

One of the most important functions that an information system must perform is data management (i.e., record keeping). Prior to the advent of true database software, computer data management was characterized by excessive data redundancy (or duplication), large data dependence (or coupling).

Computer System. The brain of the modern clinical chemistry analyzer is its computer system. The part of the computer system that controls the functional aspects of the analyzer is known as the process control computer or analytical processor (AP) the test results are handled by the data management computer, also known as the results processor (RP). 

The results processor computes the test results from the raw data furnished by the AP and coUates these results together with the demographic patient data into test reports. Test results falling outside normal limits are flagged on the report to speed up the diagnosis process. These data managers can also store thousands of patient reports in their current memory. Some of the more sophisticated systems also store the actual reaction curves used to determine the test results. 

The host computer provides all of the data management, storage, report generation, and analysis capabilities of the predictive maintenance program. Therefore, care should...

Pure paper-based data collection systems are most suitable for small and short-term studies. Their advantages are that no computer hardware or software is needed at the participating sites because data are recorded manually on paper forms that are transferred to the centralized location in batches. A major drawback is that participating sites do not have real-time access to their data because no database is created locally. However, both hardware and software are needed at the centralized location for the data management system. The type of hardware and software used is determined by the configuration of the centralized computer. The most commonly used platforms include Open VMS, Unix, or PC, and one of the most widely used software packages is SAS [16]. 

In distributed systems, each participating site must be equipped with a desktop or a laptop computer loaded with the distributed data collection system software to collect and enter data locally. In addition, each site is provided with necessary storage devices such as tapes, zip diskettes, and CDs and peripheral devices such as printers. Collected data are transferred periodically to the central location as files saved on storage devices, via phone modems, by FTP, or through wireless communications, where they are managed by a centralized data management system. 

Ph.D., performed the computer programming and statistical analysis. Candace Young and Frieda Fisher helped with data management. William Bax, Joseph Wade, Charles Bennett, Gertie King, Dennis Miles, Jimmie Pickett, Frank Porter, Deborah Richardson, and Alice Roberts collected urine samples.

Chiron provides a microwell plate heater, a luminometer, and data management software. The plate heater is specially designed to provide precise control of the hybridization temperature (0 0.5°C) and to distribute heat evenly throughout the microwell plate. The luminometer maintains a temperature of 37°C and accommodates the 96-well plates. The data management software runs on an IBM PC or compatible computer with a minimum of 80386,16-Mhz microprocessor, 2 Mb of RAM, monitor, mouse, compatible printer, MS DOS (version 5.0 or greater), and Windows (version 3.1 or greater). 

Applications of Computer Data Base Management in Polymer and Coatings Research... 

Early scientific software packages focused on compilers, individual applications, and specific aspects of computer support such as statistics. More recently, software packages provide a broad, integrated, easy to use, and extensible set of capabilities to support research data management. RS/1 (TM) is described as an example of modern scientific software. 

RS/1 represents a distinct contrast to earlier scientific software. In general, early software used by scientists took three primary forms. (1) Languages such as FORTRAN, BASIC, and PASCAL were helpful in supporting highly computational applications, but were not designed to support research data management.
