The goal of this thesis was to study the performance of three commercial object-oriented database management systems. The commercial systems studied included: Itasca, sold by Itasca Systems Incorporated; Matisse, sold by Intellitic International; and ObjectStore, sold by Object Design Incorporated. To examine performance of these database management systems two benchmarks were run: the OO1 benchmark and a new AFIT Simulation benchmark. The OO1 benchmark was designed, implemented, and run on all three database management systems. ObjectStore was our top performer on all configurations of the OO1 benchmark. The AFIT Simulation benchmark was designed, implemented, and run on the ObjectStore database management system. A nonpersistent version of the benchmark was also created in the C++ programming language. There was minimal performance overhead incurred due to the use of ObjectStore. especially when compared to the functional benefits gained. We concluded that there are major differences between the performance levels offered in current commercial object-oriented database management systems. We also concluded that a programming language interface to an object-oriented database management system should not be middle ground. Either it should be closely tied to a specific language or not tied to a specific language at all. Database benchmarks, Object-oriented databases, Simulation.

This report compares the relevant characteristics of three selected DataBase Management System (DBMS) software packages hosted on a microcomputer running the Control Program for Microcomputers(CP/M) Operating System. The candidate commercial DBMS programs (dBASE II, Condor Series 20, and FMS-80), each available at a cost of $1,000 or less, were identified and evaluated. They were compared on the basis of being simple to use and able to completely satisfy the requirements of the specified application areas of report automation, personnel record management, bibliography modification and printing, and document inventory. After intensive testing and evaluation, dBASE II was determined to be the most appropriate choice for the applications tested. (Author)

We live in the information and the microelectronic age, where technological advancements become a major determinant of our lifestyle. Such advances in technology cannot possibly be made or sustained without concurrent advancement in management systems (5). The impact of computer technology on organizations and society is increasing as new technologies evolve and existing technologies expand (5). Because of the influences of the innovations in the computer technology, people can also build their own computerized systems with easy-to-use construction tools. Management is a process by which certain goals are achieved trough the use of resources like materials, people, money, time. These resources are considered to be inputs, and the attainment of the goals is viewed as the output of the process. Database systems continue to be a key aspect of Computer Science & Engineering today. Representing knowledge within a computer is one of the central challenges of the field. Database research has focused primarily on this fundamental issue (6). This paper presents a database management system developed for AOF (Faculty of Open Education) course books. Its rationale is based on the development of a database application that share data and operations through a database. It supports organization's manipulation and retrieval of data. In order to organize large amounts of data (book's names, ISBN numbers, number printed; authors' names, and addresses, etc.) similar user interfaces are developed for different types of users. In addition, they can create special reports. It also encourages users who have no previous programming experience. The detail of the study is presented in the third part of the paper. In the second part of the paper, some knowledge about management information systems and database management systems are given.

Data is a vital resource for businesses; therefore, it is important for businesses to manage and use their data effectively. Because of this, businesses value college graduates with an understanding of and hands-on experience working with databases, data warehouses and data analysis theories and tools. Faculty in many business disciplines try to prepare students for this data-oriented business environment by teaching database and business intelligence concepts in their courses. However, many faculty may not be aware of various important online resources. For example, the Microsoft Enterprise Consortium (MEC) provides data and instructional resources to faculty in business colleges through access to several data sets that could be used for teaching a range of topics including fundamentals of database management, beginning and advanced SQL, data warehouses, and business intelligence (data mining, data cubes and dimensional reporting). The purpose of this paper is to introduce the Microsoft Enterprise Consortium, to discuss the various teaching resources it provides, to present an overview of the materials available through the MEC, and to give an example of successful implementation and utilization of MEC resources.

The purpose of this thesis was to program a database system written in dBase III Plus for use in AFIT/LSM. The system was to be hosted on a personal computer so that it could be transportable between the different computers in the office and conveniently used by as many personnel as possible. The program was intended to replace as much manual paperwork as possible and to provide a means to quickly access, sort, and to efficiently answer queries regarding the department faculty. The final result was intended to automate the routine office functions. This automation would relieve the department personnel from mundane duties so that they could concentrate their time on more productive pursuits. The product of these efforts was the Integrated Faculty Information System (IFIS). The IFIS is a menu driven system that utilizes 19 databases that are interrelated to form one large database system. The database system has the capability to contain all the vital professional and demographic information on each member of the staff. The IFIS provides a means to input all the appropriate information and to modify preexisting information within the database system. Keywords: Office automation, Computer programming, Database management systems, Databases, Personal computers, Theses.

In order to understand how the database software or online database functioned in the overall curricula, the use of database management (DBMs) systems was studied at eight elementary and middle schools through classroom observation and interviews with teachers and administrators, librarians, and students. Three overall areas were addressed: teachers' backgrounds in teaching and computers, the information-seeking activities that teachers required of their students and the curriculum context in which they occurred, and the use of the specific database system and its relationship to students' information-management skills. Results indicated that the DBMs were implemented in varied ways depending on software selection, schools' philosophies about computers, teacher selection and training, type of database activities, and problems in classroom use. Problems noted relate to the rigid information format required by software, inability of the software to allow for definition changes, limited hardware access, math and programming as exclusive domains for computer use, insufficient teacher training, limited classroom information-based activities, and students' math and reading skills. This report includes in-depth case study reports of two of the schools, a summary, conclusions, and the teacher interview guide. (LMM)

Database management systems have been developed mainly for commercial and business processing. As such, it generally manages formatted data, rather than information, which is less structured and comes in many forms such as text, graphics, images, voices, and signals. Beyond the capability of handling multimedia information, non-business application areas call for further requirement. Real-time processing, risk assessment, and partial answers are some of the more important requirements, especially in the military applications. In this paper, we discuss issues involved in creating such advanced database management system and propose some approaches.

The Systems Management Curricular Office at the Naval Postgraduate School is burdened with the enormous administrative task of managing files for over 500 students. In a time of drastic military downsizing and funding cuts, this task will require more work of a smaller staff with less money. The burden of paper management could be lessened through automation of record keeping, while increasing efficiency and effectiveness. Valuable time for the students could be saved through elimination of excessive paperwork which they were required to prepare. Based on requirements from the Systems Management Curricular Office, this thesis designs and implements a database management system. The primary objective is to allow the incoming class of students to enroll using this system instead of traditional paper forms, enabling the staff to focus on more non-administrative tasks. This system will store, sort and compare data relevant to all students while minimizing the need to maintain hardcopy files. Additionally, the staff will be able to query reports and generate letters with minimal effort. The system is also analyzed to determine possible enhancements that could be added in the future. The Systems Management Database Systems (SMDS) is designed using Borland's PARADOX version 4.0. (AN)

Much of the work to date to apply Role-Based Access Control (RBAC) to database management systems has focused on single database systems or an integrated distributed database system. For situations where the need exists to consolidate multiple independent databases, and where the direct integration of the databases is neither practical nor desirable, the application of RBAC requires that policy be enforced via a method that is distinct from the databases. The method must provide for the verification of the RBAC policy, while allowing for the independence of the various databases on which the policy is enforced. This paper proposes a model for an application that provides for a web-based interface for users to be granted access to data held in various independent databases. The application enforces a strict RBAC policy on a well-defined set of accesses, while alleviating the need for users to have a separate account on each of the databases.
