Data archiving

When the data are already in the computer, tracking lab performance using statistical techniques can be done with Htde effort. By having the data archived, historical trends can be charted and past process capabiUty compared to current capabiUty. This can be useful in responding to challenges to test results (30). The avadabihty of production data makes periodic comparison of process capabiUty to specification limits easy. 

Databases are the lingua franca—the common language—of bioinformatics. Although the kind of data archived may vary, nonetheless, the use, creation, and manipulation of databases remains the most critical feature of modern-day bioinformatics, both as a discipline in its own right and as a support for...

After the data collection phase of a clinical trial is completed and its collected data are analyzed, collected data are archived centrally, usually at the coordinating center, for future reference. The data archive method depends on the data collection system. In paper-based data collection system, the physical paper forms may need to be archived for a specified period of time. Scanning... 

The speed with which the data need to be compressed depends on the stage of data acquisition at which compression is desired. In intelligent sensors it may be necessary to do some preliminary data compression as the data are collected. Often data are collected for several days or weeks without any compression, and then stored into the company data archives. These data may be retrieved at a later stage for studying various aspects ol the process operation. 

Two general methods were used to collect data archival study and interview of key informants. 

A well-developed records management program that defines rules by which records and documents are handled from creation to retirement is necessary for a successful electronic data archiving process. In a GLP-compliant system, records are classified by type, such as study-specific raw data, reports, personnel records, etc. Each record type has a defined retention time. 

This presentation demonstrates that a small minicomputer can be used to provide a full range of functions for collection and interactive reduction of data from a size-exclusion liquid chromatograph. A number of different users have collected in excess of 5000 chromatograms using this equipment. The experience gained with this system has influenced our approach to the automation of other analytical instruments. Careful attention to control paths, provision of "user friendly" access to the system functions, and careful management of the data archiving functions are crucial to the success of such efforts.

Lloyd et al.1 described automation processes for compound optimization and simultaneous implementation of (1) a LIMS system to automate and track the flow of sample information, data analysis, and reporting (2) an automated data archiving system to handle a large number of LC/ MS/MS data files (3) custom software to track a large number of protocol flows and (4) workstation automation.

It would be a natural development to integrate robots with the logistics of the sample request system adopted in Shell and to record their output automatically in central data archives. 

Managerial control is estabhshed and documented through a series of SOPs. These SOPs are system design, use, and control pohcy statements. They summarize procedures of system security, disaster recovery, normal use, data archive and backup, error response, documentation, testing, and other important aspects of control.

A complimentary foreword must invoke the possibility of future editions. In future versions of this book, I hope that F. Rouessac and his wife will include a few additions on the analytical balance, as I have mentioned above, but also on electrochemical methods, on sampling - so rarely discussed and on the treatment of numerical data (archiving of primary data, statistical treatment, graphical representation, etc.). Or perhaps, in a volume 2 ... 

We do not have to concern ourselves with aniline-like conjugation of the -electrons of the benzene ring with the nitrogen lone-pair electrons because the n- and n-orbitals are geometrically perpendicular and so do not overlap. We also do not concern ourselves with the 5 kJ mol-1 discrepancy in the values of the enthalpy of formation of cyclopentadiene as found in Roth and coworkers54 and that which we take from our major data archive.
