    This paper reports on pertinent aspects of business/enterprise modeling studies that were conducted with nine IBM customers using what are now called computer-aided software engineering (CASE) tools. Coming shortly after the recent AD/Cycle™ announcement and the increased focus in IBM on tool-supported (CASE) business/enterprise modeling, this description of actual modeling studies should b...

    Several cryptosystems based on exponentiation have been proposed in recent years. Some of these are of the public key variety and offer notable advantages in cryptographic key management, both for secret communication and for message authentication. The need for extensive arithmetic calculations with very large integers (hundreds of digits long) is a drawback of these systems. This paper describes... View full abstract»

    A data model consists of three parts: (1) a data definition that represents the information in an understandable manner; (2) a definition of the constraints that must hold for the information to be valid; and (3) a definition of operations that can be performed on the information. Current database management systems do not allow explicit specification of all three parts of the data model. This pap... View full abstract»

    In 1986, the Federal Aviation Administration formed a contract with three companies to re-engineer a major portion of the New York terminal approach control (TRACON) application software—the software that supports air traffic control in the New York City and Newark, New Jersey, area. This paper discusses the techniques used to successfully re-engineer the software to run on an IBM System/37... View full abstract»
