Verification of Object Relational Maps

Krishna K. Mehra, Sriram K. Rajamani, A. Prasad Sistla, Sumit K. Jha
2007 Fifth IEEE International Conference on Software Engineering and Formal Methods (SEFM 2007)  
Object-Relational (OR) maps are widely used to mediate between these two data models. We present a system to verify correctness of OR maps.  ...  We have built a verification tool called ROUNDTRIP that is able to both validate and find errors in OR maps defined in the ESQL language of the Microsoft EDM data model.  ...  We thank Supratik Chakraborty for comments on a draft of this paper.  ...

Formal verification of ontology transformation for distribution network information model based on meta-model theory

Boya Qin, Dong Liu, Yiming Lu
2020 IET Cyber-Physical Systems  
The model updating and model mapping instances were specified using model checking verification tool SPIN.  ...  This study presents a formal description and verification method of the ontology transformation process of the distribution network information model based on the meta-model theory.  ...  Owing to the state space explosion problem caused by an enormous quantity of objects, attributes, and relations in different models, verification of the model mapping process is quite complicated.  ...

3D Semantic Map Computation Based on Depth Map and Video Image [chapter]

Włodzimierz Kasprzak, Maciej Stefańczyk
2012 Lecture Notes in Computer Science  
A model-based object recognition in video and depth images is proposed for the purpose of semantic map creation in mobile robotics.  ...  The verification of hypotheses is due to a top-down occlusion propagation process, that explains why some object parts are hidden or occluded.  ...  The top-down verification process for a selected subset of hypotheses consists of two steps: the initial generation of occlusion relations (between objects) and the propagation of occlusion relations from  ...

Language-Independent Model Transformation Verification

Kevin Lano, Shekoufeh Kolahdouz Rahimi, Tony Clark
2014 International Conference on Software Technologies: Applications and Foundations  
One hinderance to model transformation verification is the large number of different MT languages which exist, resulting in a large number of different language-specific analysis tools.  ...  to express the semantics of transformations in any of these languages.  ...  The output variables become exists-quantified variables of the relations of the r i mappings.  ...

Bounded verification of Ruby on Rails data models

Jaideep Nijjar, Tevfik Bultan
2011 Proceedings of the 2011 International Symposium on Software Testing and Analysis - ISSTA '11  
The use of scripting languages to build web applications has increased programmer productivity, but at the cost of degrading dependability.  ...  We then use bounded verification techniques implemented in the Alloy Analyzer to look for errors in these formal data model specifications.  ...  The only difference is that its relations always map a set of objects to another set of objects.  ...

Joseph P. Near, Daniel Jackson
