Software systems

For a variety of appHcations such as computer-aided engineering systems, software development, or hypermedia, the relational database model is insufficient. In an RDBMS, it is difficult to model complex objects and environments the various extensive tables become complicated, the integrity is problematic to observe, and the performance of the system is reduced. This led to two sophisticated object-based models, the object-oriented and the object-relational model, which are mentioned only briefly here. For further details see Refs. [10] and [11]. 

A number of files under the generic tide CAS ONLINE are available on-line on STN International. The system software, MESSENGER, includes chemical substmcture, text, and numeric data searching facHities. Chemical stmctures and Registry Numbers are contained in the CA Registry file. The four ways to search the stmctures are EXA, EAM, SSS, and CSS.

Many batch software packages also recognize process states. A configuration tool is provided to define a process state. With such a mechanism, the batch logic does not need to drive individual devices but can simply command that the desired process state be achieved. The system software then drives the discrete devices to the device states required for the target process state. This normally includes the following ...

With the combined power of the data collector and system software, data acquisition has been reduced to simple measurement routes that require limited operator input. The technician s role is to temporarily mount a transducer at the proper measurement point and push a button. The microprocessor automatically acquires conditions, evaluates, and stores the vibration data. 

In some data acquisition and processing systems, software is included that mathematically analyze convoluted (unresolved) peaks, identify the individual peaks that make up the composite envelope and then determine the area of the individual peaks. 

IBM, a leader in information technologies, produces computer systems, software, networking systems, storage devices and microelectronics. It employs over 300,000 people and operates in over 100 countries. Business Innovation Services (BIS) is the consulting and systems integration arm of IBM Global Services. The organization is the...

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. 

System software maintenance presents some challenges. System updates may be needed to fix a glitch, incorporate protocol amendments, respond to changes in business rules, add, change, or disable reports, forms, or variables.

The instrument for measurement of radon with weather parameters and water use was designed, calibrated and used in the field for 1.5 years with excellent results. The power surge and power interruptions were the only limitations on the use of the instrument. The system software was written mostly during the design phase of the project. However, modifications were made in the software to permit better data collection during power interruptions. Battery backup was needed to keep the data during interruptions of our one week studies.

Countermeasures are actions taken to reduce or eliminate one or more vulnerabilities. Countermeasures include hardware, technical systems, software, interdictive response, procedures, and administrative controls.

Finally, let us underline an important feedback loop starting at the real-time system and ending at the tool preparation station, which contains the real-time tool status, wear, and part priority information. These data are often useful to those people and/or system software systems that deal with the generation of the production rule base. It is also a very useful data set for FMS designers, since a lot of data which would previously have been lost will be saved in this way. 

In addition to testing the system components, a test of software functionality would be performed to test the system software operation and electronic records and electronic signatures (ERES) compliance (security, data integrity, data backup, and archive). In order to test the software functionality, a predetermined set of instructions can be entered step by step into the system. The system responses are then compared to the expected outcomes of the instruction and any problems with the execution are determined. Some vendors will provide a standard set of data which can be processed by the system to verify the data-handling capability of the system.
