Content Schema Evolution in the CoreMedia® Content Application Platform CAP [chapter]

Axel Wienberg, Matthias Ernst, Andreas Gawecki, Olaf Kummer, Frank Wienberg, Joachim W. Schmidt
2002 Lecture Notes in Computer Science  
To control the inevitable evolution of the content schema, the schema should be subject to configuration management together with the actual content.  ...  We propose a two-layered approach to content schema evolution consisting of a system level responsible for bookkeeping and integrity issue detection, and a semi-automatic application level responsible  ...  The CoreMedia Meta-Model In this section, we describe our meta-model, i.e., our language for expressing a schema and for expressing content.  ...

Rich Base Schema

Sang-Won Lee, Hyoung-Joo Kim
2000 Journal of Database Management  
In this paper, we propose a model of schema versions for object-oriented databases called RiBS. At the heart of this model is the concept of the Rich Base Schema (RiBS).  ...  As the third element of our model, we give a set of schema update operations, of which semantics are defined so as to preserve all the invariants.  ...  Operations We give a set of operations for managing schema versions, which is the last component of the RiBS model.  ...

Mohammad Ghulam Ali
2010 International Journal of Computer Applications  
In our approach, we considered the object-oriented data model as common data model constructing a global conceptual model by set of integration operators.  ...  In this paper we consider uniform object-oriented data models which is used during integration of different heterogeneous distributed databases from different data models and proposed a framework to maintain  ...  Mapping of Local Heterogeneous Schemas with Common Global Schema Framework for Model independent Replication Agent We propose every local heterogeneous database management system will have model independent  ...

Evolution of Schema and Individuals of Configurable Products [chapter]

Tomi Männistö, Reijo Sulonen
1999 Lecture Notes in Computer Science  
Therefore, a new conceptual framework for product data management systems of configurable products that allows relatively independent evolution of schema and instances is proposed. − The basic concepts  ...  Description and management of a large product variety within a single data model is challenging and requires a solid conceptual basis.  ...  We model both the schema and the individuals with the same concepts. The basic concepts are object and relation between objects.  ...

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  ...  Its main objective is to ensure the autonomy of the component databases, their management and independent handling.  ...

2003 36th Annual Hawaii International Conference on System Sciences, 2003. Proceedings of the  
Our Distributed Telecommunication Management System (DTMS) uses an object-oriented model to describe the networked Voice Communication System (VCS) to be managed.  ...  All other components have either to be VCS-independent or to be generated from the VCS model.  ...  modeling process has been introduced, which coherently encapsulates all aspects of the managed VCS (the problem domain) in a conceptual and detailed VCS model applying object-oriented modeling techniques  ...

Enabling More Human-Oriented Exploration of Complex Building Information Models

Katrin Wender, Reinhard Hübler
2009 Journal of computing in civil engineering  
A "raw" building information model schema has been enhanced by user-oriented associations between particular data objects, referred to in this paper as "navigation links."  ...  Each link is defined as a new property of a particular concept of the building model schema. Such a link points to a query recipe that can retrieve information about each instance of the concept.  ...  A fire protection model or a damage/ deficiency model for example might be such IFC independent domain models.  ...

Aggregation Transformation of XML Schemas to Object-Relational Databases [chapter]

Nathalia Devina Widjaya, David Taniar, Wenny Rahayu
2003 Lecture Notes in Computer Science  
Then, a number of transformation steps from the XML schema to the ORDB, with the emphasis on the transformations of aggregation relationships are presented.  ...  In this paper, we present the way to transform the XML encoded format, which can be treated as a logical model, to the ORDB format.  ...  Lastly, create a primary key and a foreign key. ORDB: Create Below is the mapping of ORDB for existence independent from the XML Schema existence independent aggregation.  ...

Tool integration and construction using generated graph-based design representations

Ansgar Bredenfeld, Raul Camposano
1995 Proceedings of the 32nd ACM/IEEE conference on Design automation conference - DAC '95  
We provide a framework service based on this model which generates implementations of graph-based design representations from a conceptual schema.  ...  In this paper we present a new data model for tool integration that extends existing data models by an abstract graph model.  ...  Abstract Graph Schema The object model provides constructs to describe data in a schema. These constructs reflect the modelling concepts of the object model.  ...

Managed data

Alex Loh, Tijs van der Storm, William R. Cook
2012 Proceedings of the ACM international symposium on New ideas, new paradigms, and reflections on programming and software - Onward! '12  
In this paper we argue for the importance of Managed Data and present a novel implementation of Managed Data based on interpretation of data models.  ...  We also show how self-describing data models are useful for bootstrapping, allowing Managed Data to be used definition of Data Managers themselves.  ...  While the concept of Managed Data is independent of the particular data description language being used, it is worth noting that the Ensō Schema schema is closely related to a large body of existing work  ...
