Abstract object types for databases [chapter]

H. -D. Ehrich, A. Sernadas, C. Sernadas
1988 Lecture Notes in Computer Science  
~ -There is a need for exploring the theoretical and methodological foundations of database design and development with the intention to achieve provably correct systems and higher levels of reusability  ...  In analogy to algebraic data type theory, we propose mathematical models for the basic notions of object, object type and abstract object type.  ...  Introduction What is a database object in the sense of object-oriented databases? How are database objects put together into object types? What is an abstract object type?  ...

Fitting Round Objects Into Square Databases [chapter]

D. C. Tsichritzis, O. M. Nierstrasz
1988 Lecture Notes in Computer Science  
Object-oriented systems could use much of the functionality of database systems to manage their objects.  ...  We discuss the ways in which this difference in outlook manifests itself, and we consider the possibilities for resolving the two views, including the current work on object-oriented databases.  ...  We can view this approach as providing another (square) database-oriented interface to objects.  ...

Specifying global behaviour in database federations

Mark W.W. Vermeer, Peter M.G. Apers
1998 Information Systems  
We discuss the impact of locally implemented behaviour on global behaviour specification in a federation of object-oriented databases.  ...  To this end, we develop the notions of objectivity and subjectivity of local methods, indicating whether the execution of a local method affects the global view exactly as it affects the local database  ...  INTRODUCTION Object-oriented database interoperation concerns the definition and operation of a federation of number of pre-existing, heterogeneous and autonomous object-oriented databases.  ...

Business Suitability Principles for Workflow Modelling [article]

Alistair P. Barros, Arthur H. M. ter Hofstede, Henderik A. Proper, Peter N. Creasy
2021 arXiv   pre-print
A general assessment is first conducted on some integrated techniques characterising well-known paradigms - structured process modelling, object-oriented modelling, behavioural process modelling and business-oriented  ...  By incorporating aspects of coordination and collaboration, workflow implementations of information systems require a sound conceptualisation of business processing semantics.  ...  In fact, event-condition-action (ECA) paradigm for rule-based languages is adopted in active database technology, e.g. in context with object-oriented databases [CN90] , and object-oriented conceptual  ...

Literature review of spatio-temporal database models

NIKOS PELEKIS, BABIS THEODOULIDIS, IOANNIS KOPANAKIS, YANNIS THEODORIDIS
2004 Knowledge engineering review (Print)  
Orientation/Direction: This standard demonstrates whether a model supports the orientation and the direction features that real world objects show in space (e.g. on the left side of, to the right).  ...  Recent efforts in spatial and temporal data models and database systems attempt to achieve an appropriate kind of interaction between the two areas.  ...  From a theoretical point of view the author proposed a datatype-oriented model that supports the representation of objects both under object-oriented and object relational platforms.  ...

Behaviour specification in database interoperation [chapter]

Mark W. W. Vermeer, Peter M. G. Apers
1997 Lecture Notes in Computer Science  
We discuss the impact of locally implemented behavi0ur in a federation of object-oriented databases.  ...  To this end, we develop the notions of objectivity and sub-jecti~i~y of local methods, indicating whether the execution of a local method affects the global view exactly as it affects the local database  ...  We use the behaviour specification possibilities offered by the object-oriented database specification language TM [1] .  ...

Visualization of rule behaviour in active databases [chapter]

Tomas Fors
1995 Visual Database Systems 3  
One of the characteristics of database systems is the ability to efficiently handle large amounts of information.  ...  Hence, active database systems need to manage both a large amount of data and many rules. One ofthe problems with large sets of rules is the complexity of interaction between rules.  ...  If these ideas were to be fitted to the relational model, it is likely that we would turn from an instance-oriented view to a set-oriented view.  ...

From Object-Oriented to Aspect-Oriented Databases [chapter]

Awais Rashid, Elke Pulvermueller
2000 Lecture Notes in Computer Science  
This paper brings the notion of aspects to object-oriented databases. Some cross-cutting concerns are identified and addressed using aspects.  ...  An aspect-oriented extension of an OODB is discussed and various open issues pointed out.  ...  Reflecting on the fact that AOP is not limited to object-oriented programming languages [19] , we are of the view that aspects can be employed in database technology other than OODBs e.g. relational,  ...

Viewpoints: a framework for object oriented database modelling and distribution

Fouzia Benchikha, Mahmoud Boufaida, Lionel Seinturier
2005 Data Science Journal  
Its integration into a data model improves the flexibility of the conventional object-oriented data model and allows one to improve the modelling power of objects.  ...  The contribution of this paper is twofold: to define an object data model integrating viewpoints in databases and to present a federated database system integrating multiple sources following a local-asextended-view  ...  THE VIEWPOINT CONCEPT IN DATABASES In the field of databases, the concept of viewpoints is mainly investigated within the concept of views and roles in the object-oriented database community.  ...
