چکیده

Trans [1] is a Lisp system at the Space Telescope Science Institute (STScI) which is a key part of the proposal preparation ground system for the Hubble Space Telescope (HST). It was originally developed in the late ‘80s using a mixture of procedural, and blackboard architectures. While the original application met its requirements and performed well for a number of years, the increasing complexity of the system and its changing role meant that it eventually needed to be re engineered.

Objects Identification in Object-Oriented Software Development - A Taxonomy and Survey on Techniques

Analysis and design of object oriented is onemodern paradigms for developing a system. In this paradigm, there are several objects and each object plays some specific roles. Identifying objects (and classes) is one of the most important steps in the object-oriented paradigm. This paper makes a literature review over techniques to identify objects and then presents six taxonomies for them. The f...

Declarative Semantics in Object-Oriented Software Development - A Taxonomy and Survey

One of the modern paradigms to develop an application is object oriented analysis and design. In this paradigm, there are several objects and each object plays some specific roles in applications. In an application, we must distinguish between procedural semantics and declarative semantics for their implementation in a specific programming language. For the procedural semantics, we can write a ...

On Attributes of Objects in Object-Oriented Software Analysis

One of the modern paradigms to develop a system is object oriented analysis and design. In this paradigm, there are several objects and each object plays some specific roles. There is a sequence of activities to develop an analysis model. In the first step, we work in developing an initial use case model. Then in the second step, they identify a number of concepts and build a glossary of partic...

An Active Object-Oriented Database: A Multi-Paradigm Approach to Constraint Management

Mb describe the design and implementation of a constraint management facility for our active object-oriented database system called Jasmine/A. The facility includes integrity constraints, events/triggers, and constraint rules. The facility enables the user to handle both interobject and intraobject constraints, to define both primitive and composite events, and to populate databases with values...

Specification and Implementation of Consistency Constraints in Object-Oriented Database Systems: Applying Programming-by-Contract

We describe an approach to the specification and implementation of consistency constraints in object-oriented database systems, adopting the programming-by-contract paradigm developed for object-oriented programming. We also investigate how consistency constraints specified in programming-by-contract can be transformed into production rules of an active, object-oriented database system.
