Emerging business models for the open data industry

Fatemeh Ahmadi Zeleti, Adegboyega Ojo, Edward Curry
2014 Proceedings of the 15th Annual International Conference on Digital Government Research - dg.o '14  
However, scholarly efforts providing elaborations, rigorous analysis and comparison of open data models are very limited.  ...  This shortcoming has resulted in a growing list of open data business models which, on closer examination, are not clearly delineated and lack clear value orientation.  ...  The lack of rigour (e.g. the use of a proper conceptual framework) in describing and analyzing existing Open Data Business Models (ODBMs) makes delineation and comparison of the models difficult.  ...

Object model sources of leverage In the previous section, I asserted that full sup- port for the object model in an ODBMS was a major 282 ALFRED source of its potential leverage.  ...  In an object-oriented model, each object is an in- stance of some class. Different classes, however, may be related by inheritance.  ...

Comparing the Performance of Object and Object Relational Database Systems on Objects of Varying Complexity [chapter]

Reza Kalantari, Christopher H. Bryant
2012 Lecture Notes in Computer Science

Strategies for processing ad hoc queries on large data warehouses

Kurt Stockinger, Kesheng Wu, Arie Shoshani
2002 Proceedings of the 5th ACM international workshop on Data Warehousing and OLAP - DOLAP '02  
In this paper, we summarize our experience of implementing a number of bitmap index schemes on vertically partitioned data tables.  ...  As data warehousing applications grow in size, existing data organizations and access strategies, such as relational tables and B-tree indexes, are becoming increasingly ineffective.  ...  The authors wish to express our sincere gratitude to Theodore Johnson of AT&T Research for permitting us to use his BBC implementation in our bitmap indexing program.  ...

State-Complexity Reduction in MLSD Receivers for Optical Communications With Direct Photodetection

Michele Franceschini, Gianluigi Ferrari, Riccardo Raheli, Fausto Meli, Andrea Castoldi

Survey of Object Oriented Mining for XML Data

T. Sangeetha, G.Sophia Reena, T. Priya
2011 International Journal of Computer Applications  
The content of the element (text nodes and elements) can be stored in a special attribute of the object.  ...  To map XML data to our system we can use the following mapping: XML elements can be processed similarly to the objects in object-oriented data.  ...  In essence, we ask you to make your paper look exactly like this document. The easiest way to do this is simply to download the template, and replace the content with your own material.  ...

2002 Lecture Notes in Computer Science  
Roles of a metamodel in an objectoriented database management system are presented and compared to the proposal defined in the ODMG standard of object-oriented database management systems.  ...  A metamodel definition presents some important issues in the construction of an object database management system, whose rich data model inevitably increases the metamodel complexity.  ...  Some complexity in comparison to the relational model is inevitable, as a minor cost of major advantages of the object model.  ...
