Given the current rapid development of informatization, people will increasingly use online teaching methods to learn for their quality improvement. Starting from the fundamental theories, such as the concept, classification, basic process, task, and method of data mining under the background of Internet Plus, this article analyzes the problems…

A detailed work plan is presented for the conduct of Phase II activities, which are concerned with creating a pilot test file, conducting a test of it, evaluating the process and input of the file, and preparing the file management plan. Due to the outcomes of activities in Phase I, this plan was revised from an earlier outline. Included in the…

Presents a database system development model in which theoretical support in the form of automated theorem proving is brought to bear on the problem of enforcing integrity, i.e., ensuring that the database system represents only those states and transitions that are possible in the world it models. (MBR)

A management information system (MIS) is applied to a medium sized general museum to reflect the actual curatorial/registration functions. The recordkeeping functions of loan and conservation activities are examined since they too can be effectively handled by computer and constitute a complementary data base to the accession/catalog information.…

Discusses the problems encountered and solutions adopted in application of the ADABAS database management system to the ECDIN (Environmental Chemicals Data and Information Network) data bank. SIMAS, the pilot system, and ADABAS are compared, and ECDIN ADABAS design features are described. Appendices provide additional facts about ADABAS and SIMAS.…

This manual provides electrical and electronic engineers with an introduction to online information retrieval as implemented on the DIALOG information retrieval system. Sections cover: (1) the development of computerized information retrieval; (2) its advantages; (3) the equipment needed, DIALOG hours of availability, methods of access, and cost…

Examines various types of link list structures built on top of the traditional random access files for application to a database query technique involving multiple keys, and shows how the technique can improve performance of traditional random access files for the Grants Information System. (Author/CMV)

Describes how the Orange County (Florida) Library System separated walk-in and phone-in reference services. Discusses telephone reference services, the Quest Line database, staffing and resources, results, and keys to success. Includes the Quest Line work flow chart. (PEN)

Describes the use of a microcomputer system to generate a personal database of books read by adding titles, displaying title/author information, and editing title/author information and discusses the system design, i.e., file structure (author index, book index, book, author), the main driver, function subroutines, and screen subroutines. (EJS)

For the last 10 years, the Duval County School System (Jacksonville, Florida) has accumulated extensive student performance data with its district-wide criterion referenced testing program (the Essential Skills Test for K-6 students and the Minimum Level Skills Test for grades 7-12), which tests over 100,000 students yearly. The research project…

The creation of Japan/MARC--a system employing Kanji script (Chinese characters as adopted by the Japanese)--as the online database for Japanese bibliographic records marks a significant development in the availability of the Japanese national bibliography and should give stimulus to other countries using Chinese as a predominant language.…

Since 1966 the libraries of the Associated Claremont Colleges have developed an automated central acquisition and cataloging system. This system differs from most other technical service organizations and operations in three ways: (1) ordering and cataloging operations are integrated and blended to avoid duplicate and uncoordinated performance,…

The problems faced in accessing the contents of online bibliographic data bases are assessed, and current training techniques are summarized and evaluated. A new training program, which delivers training to the trainee's home terminal, simulating interactive retrieval systems that search files and provide messages and displays, is described. (JPF)

Presents a description of the computer simulation model developed by the National Educational Finance Project for use by States in planning and evaluating alternative approaches for State support programs. Provides a general introduction to the model, a program operation overview, a sample run, and some conclusions. (Author/WM)
