Data Base Methods in Educational Measurement Research
… research is managing large, complex, changing data files. Conventional file management methods are needlessly expensive, difficult to implement and error-prone. In this dissertation it is shown that the network data base model can be used to expeditiously manage very large files. A data base …

A quantitative approach to data base design
… of an information system is to identify the data elements. This is usually followed by the design of the hierarchic structure of the database. Application programs are then designed to form the operational portions of the system. This approach suffers from the drawback that the processing in …

Establishment of Data Base for Survey of Rare Disease
"희귀난치성 질환은 발생률이나 유병률이 매우 낮아 일반 의료계에도 잘 알려져 있지 않아서 정확한 진단을 받는데 어려움이 있을 뿐 아니라 효율적인 치료제가 개발되어 있지 않은 경우가 대부분이다. 희귀난치성 질환은 그 질환마다 각각의 특징이 있어서 남녀의 비율이나, 연령대, 직업 등이 다양하며, 질환별로 진단의 시기 및 유전자 검사 등의 유무도 다양하다. 이러한 희귀난치성 질환의 특성을 고려할 때, 무엇보다도 질환에 대한 정확한 정보가 중요하다. 미국에서는 1983년에 140개가 넘는 희귀난치성 질환 관련 민간 비영리 봉사 단체가 …

A protection model for distributed data base management systems
Security is important for Centralized Data Base Management Systems (CDBMS) and becomes crucial for Distributed Data Base Management Systems (DDBMS) when different organizations share information. Secure cooperation can be achieved only if each participating organization is assured that the data it …

A transportable natural language front-end to data base management systems
… of front-end natural language processors to data base management systems, transporting the processor to various data base management systems has proven to be elusive. A transportable system must be modular; it must be able to adapt to radically different data domains; and it must be able to …

A User-Oriented Conceptual Schema Model of A Data Base With A Supporting Design Strategy
The data model to generate the conceptual schema should make it easier for users to understand and to express the information in the data base, but this consideration is most often ignored by the conventional data models currently in use today. Understandability and expressiveness of a data base …
