Semantic database modeling: Survey, applications, and research issues

by Richard Hull, Roger King - ACM Computing Surveys , 1987
"... Most common database management systems represent information in a simple record-based format. Semantic modeling provides richer data structuring capabilities for database applications. In particular, research in this area has articulated a number of constructs that provide mechanisms for representi ..."

for representing structurally complex interrelations among data typically arising in commercial applications. In general terms, semantic modeling complements work on knowledge representation (in artificial intelligence) and on the new generation of database models based on the object-oriented paradigm

N.: Database Application Programming with Versioned Complex Objects

by Udo Nink , Norbert Ritter - Proc. Conf. on Advanced Database Systems (BTW‘97). Informatik aktuell , 1997
"... Abstract Database systems as basis for CAD frameworks have to provide data management as well as transaction management facilities meeting the requirements of design applications. One of the most important features is an application programming interface (API) supporting design tool implementation ..."

as well as integration of design tools into the CAD framework by integrating a database language into a host programming language. Different integration techniques have been proposed in the past. We argue that call interfaces are the choice for object-oriented environments. Especially, code generation can

Object Oriented Mutation Applied in Java Application programming Interface and C++ Classes

by Mr. Titu, Singh Arora, Prof Ravindra Gupta
"... Mutation analysis is a powerful and computationally expensive technique that measures the effectiveness of test cases for revealing faults. The principal expense of mutation analysis is that many faulty versions of the program under test, culled mutants, must be repeatedly executed. We survey severa ..."

several aspects of reconstruction of complex object-oriented faults on the java API. Application of object-oriented mutation operators in java programs using a parser-based tool can be precise but requires compilation of mutants. In this paper we approach the mutation on Object Oriented features to test

Programming with Live Distributed Objects

by Krzysztof Ostrowski, Ken Birman, Danny Dolev, Jong Hoon Ahnn , 2008
"... Modern software design has embraced components. Developers who exploit the associated tools and strongly-typed object-oriented languages can be more productive. However, existing tools don’t go as far as they could with respect to distributed applications. These are often tightly coupled to complex ..."

to complex underlying communication substrates and require that developers work through procedure-call APIs, even when using modern SOA platforms. We propose a new application development paradigm and a platform, in which instances of distributed protocols are modeled as “live distributed objects”. Live

Legion -- a view from 50,000 feet

by Andrew S. Grimshaw, Wm. A. Wulf , 1996
"... The coming of giga-bit networks makes possible the realization of a single nationwide virtual computer com-prised of a variety of geographically distributed high-pe6ormance machines and workstations. To realize the potential that the physical infrastructure provides, soft-ware must be developed that ..."

A LOOPN++ Interface to an Object Data Management System

by Clayton Armstrong, Computing Honours , 1997
"... Object Data Management Systems (ODMSs) are a relatively new type of information management tool. They have emerged to provide support for the management of complex data in data-intensive applications like ComputerAided Design and Computer-Aided Software Engineering. We develop an interface to an ODM ..."

Constrained Objects for Modeling Complex Systems

by Bharat Jayaraman Pallavi, Bharat Jayaraman, Pallavi Tambay , 2000
"... The goal of this research is to develop a programming language and execution environment for modeling complex engineering entities. We propose to model complex systems using a compositional approach. The building blocks in this approach are objects whose internal states must obey a set of invaria ..."
Abstract - Add to MetaCart
of invariants, or constraints. When such objects are aggregated to form a complex object, their internal states might further have to satisfy interface constraints. This paradigm of objects is referred to as constrained objects, and may be regarded as a declarative form of object-oriented programming. We

An Object Model Interface for Supporting Method Storage

by Dalen Kambur, Damir Bećarević, Mark Roantree - in In proceedings of the 7th East European Conference on Advances in Databases and Information Systems ADBIS , 2003
"... Abstract Current object-oriented and object-relational databases provide only basic support for handling multimedia and other complex data. This is limited to storing an object’s state and the definition of behaviour rather then actual functionality. The EGTV project focuses on the integration of la ..."

of large multimedia databases, and thus requires a stronger, richer object-oriented model. The model employed in this research facilitates the definition of behaviour using standard programming languages such as C++ or Java, and provides updatability of query results (where possible). This requires

Progress: a Toolkit for Interactive Program Steering

by Jeffrey Vetter, Karsten Schwan - In Proceedings of the 1995 International Conference on Parallel Processing , 1995
"... Interactive program steering permits researchers to monitor and guide their applications during runtime. Interactive steering can help make end users more effective in addressing the scientific or engineering questions being solved with these programs, and it may be used to improve the performance o ..."

Users instrument their applications with library calls and then steer parallel applications with Progress' runtime system. Progress provides steerable objects which encapsulate program abstractions
