The type of system chosen determines the types of hardware and software needed. It also determines the processes for acquiring the necessary hardware and software. The hardware selection may include desktops, laptops, printers, scanners, fax machines, and storage devices, and the software selection includes the system development software, the database management software, the data communication software, the data conversion software, specialized proprietary software, servers, and hrewalls. 

There are disadvantages too. Some databases do not include all of the material available in conventional form for example, much of the early Chemical Abstracts is not available on-line. Another problem is that the software for on-line searching is relatively complex, so it is more difficult to learn and, as a result, on-line searches by inexperienced users can be unreliable. The increasing use of personal computers and graphical input and output have made database searching much easier but a good understanding of the software is stUl essential. Finally the cost of hardware, software, consumables, and the searches themselves, can be considerable. 

List of critical applications and operations. It should be a company s policy to set up an offsite processing center with the same hardware-software setup. This should be able to be made operational within 2 h should it become necessary if a disaster strikes the data center. Critical applications and operations include upcoming NDA studies, safety database, NDA summaries. 

The DQ process begins as soon as the URS has been produced and then effectively continues until the implementation of the LIMS in terms of hardware, software and database configuration. The objective of the DQ is to ensure that a high-quality system is ultimately installed, thus giving the pharmaceutical manufacturer a system in which there is a high level of confidence. Quality can only be built into the design and implementation of the LIMS it cannot be tested in afterward. DQ should therefore be considered as the development of the project, following which the project will move into... 

The following systems or system components can be distinguished local area network (LAN), wide area network (WAN), network operating system (NOS), operating system (OS), application software, database management software, standard application software, hardware, documentation and Standard Operating Procedures (SOPs). Table 13.1 provides examples of systems and components, and the types of changes that may occur with each system or component. 

The models, data files, and supporting documentation should be maintained, and each version of a model or data file that impacts requiremmts, designs, or decisions should be saved in the integrated database. Models may be digital, partial, or complete and may be hardware, software, or a combination of both, or may include human models or human-in-the-loop simulations or mock-ups for usability testing and workload measurement.

IT infrastructure flexibility refers to the extent to which systems (i.e. hardware, software, communication technologies, and database) are easily reconfigurable to support different business applications and services. IT infrastructure comprises information and communication technologies as well as shared technical platforms and databases (Ross et al. 1996 Weill et al. 1996 Bharadwaj 2000). The primary constituents of IT infrastructure are computing platform (hardware and operating systems), communications network, critical shared database, and core applications (Byrd and Turner 2000). IT infrastructure is the foundation of IT assets (i.e., technical and human assets) and services shared across a firm (Piccoli and Ives 2005). As a result, IT infrastructure provides shared foundation for the delivery of business applications and services (Broadbent and Weill 1997). 

The results of the study confirm that IT resources have a significant positive, direct impact on lOS appropriation (Hi). The results show that IT infrastructure provides a common foundation (e.g., hardware, software, communication technologies, and databases) for the delivery of business applications and services, and thus flexibly... 

With better hardware and software, more exact methods can be used for the representation of chemical structures and reactions. More and more quantum mechanical calculations can be utilized for chemoinformatics tasks. The representation of chemical structures will have to correspond more and more to our insight into theoretical chemistry, chemical bonding, and energetics. On the other hand, chemoinformatics methods should be used in theoretical chemistry. Why do we not yet have databases storing the results of quantum mechanical calculations. We are certain that the analysis of the results of quantum mechanical calculations by chemoinformatics methods could vastly increase our chemical insight and knowledge. 

Budgeting. These changes in the storage and retrieval of chemical information requite that Hbraries and information centers now consider not only what should be purchased but also what monies should be allocated for the purchase of information in nonprint formats such as CD-ROMs (compact disk read-only memory) and on-line databases. Coupled with this is budgeting for the cost of hardware and software to enable the rapid and cost-effective deHvery of needed information (15). The geometric increase in sources, both printed and on-line, has increased the role of information speciaHst as an expert in the deHvery of chemical information. Retrieval from increasingly diverse and complex sources becomes the paramount issue for searchers of chemical Hterature in the 1990s. 

Private (EPA) Databases. The U.S. EPA maintains a Hst of approximately 600 current information systems, as weU as some of the models and databases used within the organi2ation. The Hst is pubHshed in Information Systems Inventoy (ISI) which is updated yearly and maintained by the Information Management and Services Division of the Office of Information Resources Management (109). ISI Hsts the system name and acronym, system level, responsible organi2ation, contact person, legislative authorities, database descriptors, access information, hardware and software, system abstract, and keywords. 

The hardware and software used to implement LIMS systems must be vahdated. Computers and networks need to be examined for potential impact of component failure on LIMS data. Security concerns regarding control of access to LIMS information must be addressed. Software, operating systems, and database management systems used in the implementation of LIMS systems must be vahdated to protect against data cormption and loss. Mechanisms for fault-tolerant operation and LIMS data backup and restoration should be documented and tested. One approach to vahdation of LIMS hardware and software is to choose vendors whose products are precertified however, the ultimate responsibihty for vahdation remains with the user. Vahdating the LIMS system s operation involves a substantial amount of work, and an adequate vahdation infrastmcture is a prerequisite for the constmction of a dependable and flexible LIMS system. 

Additional database space must be allocated when intermediate data points are used. A system can be designed to use process I/O points as intermediates. However, the data acquisition software must be programmed to bypass these points when scanned. All system builders provide virtual data point types if the intermediate data storage scheme is adopted. These points are not scanned by the data acquisition software. Memory space reqmrements are reduced by eliminating unnecessary attributes such as hardware addresses and scan frequencies. It should be noted that the fiU-iu-the-forms technique is apphcable to all data point types. 

The use of computers in design and related fields is widespread and will continue to expand. It is increasingly important for designers to keep up to date continually with the nature and prospects of new computer hardware and software technologies. For example, plastic databases, accessible through computers, provide product designers with property data and information on materials and... 

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]. 

Such systems can reside on the organization s intranet or over the Internet. Various types of hardware and software are needed to host a website. The hardware includes switches, gateways, and routers. Software includes, among others, application servers, database servers, web servers, authentication servers, and firewalls. On the other hand, the only hardware and software... 

Various issues must be considered before deciding on the type of the data collection and management system. The wide range of computer programming languages, database management, proprietary software, and hardware provide for the ability to select the most appropriate system design for a trial.
