Development of an experimental hospital database system using a relational database management system.

The development of an integrated database system for the satisfactory support of the information processing requirements of a modern hospital is clearly a major task with many associated problems. A design and implementation procedure for the development of a relational hospital database system based on an experimental relational database management system is presented which should help overcome some of the problems currently encountered. A brief outline of the application and the underlying database management system is given and a standardized procedure for the design of the multilevel database schemata is presented. The associated problems and procedures required for such a development are also examined and a number of theoretical conclusions and claims are tested in a real life application environment.

A database management system for radiation safety program activities.

The Database Management System includes a data retrieval system for most aspects of the radiation safety program at our institution. Originally, this program was designed to simplify the retrieval of data related to radioisotope use at the institution. After several modifications and changes, the present system is more elaborate and uses current commercial software, which is more readily available to the entire university and hospital community. The data included in the database are radioactive material receipts and inventory; radioisotope waste inventory and disposal; quarterly laboratory inspection results; contamination (wipe tests) results and instrument inventory and calibration; and support staff training. Both the authorized users and the Radiation Safety Office personnel maintain records independently using the same format, which makes for easy comparison and verification. Data for and from laboratory inspections are readily accessed, analyzed, and reported. The system allows for modifications as necessitated by changes in local and federal regulations or in-house policies.

Microcomputer-assisted filing system of cardiac catheterization records using a relational database management system.

To efficiently store and retrieve cardiac catheterization records, we have developed a computer-assisted database, which comprises a 16-bit microcomputer with dual floppy disk drives, a 20 MB random-access memory, hard disk drive, and a line printer. All programmings were accomplished using a relational database management system (R:base 5000, Microrim, Inc.). Data inquiry procedures could be performed with direct operational commands of the system as well as with preprogrammed command files, and final results of searches were printed out with a line printer. The major advantages of the present system described in this report include: (1) the relatively easy and rapid creation of the database, (2) ease of modification of the database structures even after the system design is finished, (3) operational commands in combination with conditional operator(s) are flexible and powerful enough to allow the end user to retrieve data based on various kinds of criteria, (4) a high-level programming language provided by the R:base automates a series of database procedures with relative ease, (5) relational capabilities of the database management system can enhance the possibility of reconstruction of a new data file from a single or several preexisting data files, and (6) the system can be realized at reasonable cost.

[The future of clinical laboratory database management system].

To assess the present status of the clinical laboratory database management system, the difference between the Clinical Laboratory Information System and Clinical Laboratory System was explained in this study. Although three kinds of database management systems (DBMS) were shown including the relational model, tree model and network model, the relational model was found to be the best DBMS for the clinical laboratory database based on our experience and developments of some clinical laboratory expert systems. As a future clinical laboratory database management system, the IC card system connected to an automatic chemical analyzer was proposed for personal health data management and a microscope/video system was proposed for dynamic data management of leukocytes or bacteria.

A review of database management systems suitable for neuroimaging.

This study comprises a technical assessment of Database Management Systems (DBMS), which may be of use in the analysis of data obtained from human brain mapping procedures. Due to the large expansion of the neuroimaging field, the use of specialized database software to store and process neuroimages and their attached components is inevitable. The advent of multiple software products, a wealth of technical terms and a wide variety of other applications make the choice of a suitable program sometimes difficult. Through the inclusion of some basic and pertinent criteria (e.g., performance, ease of opening, standardization and portability), we present a descriptive comparison of 12 DBMSs currently available in the commercial and public domain. We have compared and tested three main architecture models which are currently available and assessed their potential applications for imaging purposes: relational, object-oriented, and hybrid. The findings of our study demonstrated that the Illustra software was the best suited for a neuroimaging environment because of its intrinsic ability to handle complex and large objects, such as 3D volumes or geometric structures.

An improved FORTRAN 77 recombinant DNA database management system with graphic extensions in GKS.

We have improved an existing clone database management system written in FORTRAN 77 and adapted it to our software environment. Improvements are that the database can be interrogated for any type of information, not just keywords. Also, recombinant DNA constructions can be represented in a simplified 'shorthand', whereafter a program assembles the full nucleotide sequence from the contributing fragments, which may be obtained from nucleotide sequence databases. Another improvement is the replacement of the database manager by programs, running in batch to maintain the databank and verify its consistency automatically. Finally, graphic extensions are written in Graphical Kernel System, to draw linear and circular restriction maps of recombinants. Besides restriction sites, recombinant features can be presented from the feature lines of recombinant database entries, or from the feature tables of nucleotide databases. The clone database management system is fully integrated into the sequence analysis software package from the Pasteur Institute, Paris, and is made accessible through the same menu. As a result, recombinant DNA sequences can directly be analysed by the sequence analysis programs.

Cardiological database management system as a mediator to clinical decision support.

An object-oriented medical database management system is presented for a typical cardiologic center, facilitating epidemiological trials. Object-oriented analysis and design were used for the system design, offering advantages for the integrity and extendibility of medical information systems. The system was developed using object-oriented design and programming methodology, the C++ language and the Borland Paradox Relational Data Base Management System on an MS-Windows NT environment. Particular attention was paid to system compatibility, portability, the ease of use, and the suitable design of the patient record so as to support the decisions of medical personnel in cardiovascular centers. The system was designed to accept complex, heterogeneous, distributed data in various formats and from different kinds of examinations such as Holter, Doppler and electrocardiography.

Integrated clinical decision support using an object-oriented database management system.

Clinical decision support systems assist in diagnosis, alert to abnormal conditions, and manage patient data. Such systems tend to emphasize one of these features at the expense of the others and tend to be developed on an ad hoc basis. In this work, a technique is developed for creating an integrated clinical decision support system wholly within a general-purpose object-oriented database management system. The diagnostic and alerting requirements are accomplished with encapsulated methods and a novel use of the object-oriented database management class-hierarchy structure. The patient data management requirement is satisfied by the normal data management capabilities of the object-oriented DBMS.
