Introducing Custom Language Extensions to SQL:1999 [chapter]

Jernej Kovse, Wolfgang Mahnke
2003 Lecture Notes in Computer Science  
A translator system uses information imported from the packages to translate the statements containing the extensions into SQL:1999-compliant statements.  ...  This paper describes the idea of language extensions to SQL:1999 that come in form of independent packages and may be implemented by different vendors.  ...  We do not want to present the framework in detail, an excerpt of this framework may illustrate the idea of modular extensions of SQL:1999. The framework consists of different kinds of schema modules.  ...

Private and Scalable Execution of SQL Aggregates on a Secure Decentralized Architecture

Quoc-Cuong To, Benjamin Nguyen, Philippe Pucheral
2016 ACM Transactions on Database Systems  
The new material covers a set of important problems that need to be solved to make the approach practical: cryptographic key management, accuracy and latency of the collection phase, access control management  ...  It also discusses how the resulting querying protocols can be integrated in a concrete decentralized architecture.  ...  ACKNOWLEDGMENTS The authors wish to thank Anne Cantaut from INRIA-SECRET team and Matthieu Finiasz from CryptoExperts for their help in defining and proving the security of our GKE protocol, and Philippe  ...

PRIME---toward process-integrated modeling environments: 1

Klaus Pohl, Klaus Weidenhaupt, Ralf Dömges, Peter Haumer, Matthias Jarke, Ralf Klamma
1999 ACM Transactions on Software Engineering and Methodology  
These lessons are explored in the paper.  ...  The approach is based on theories of communicative activity as language faction and has been developed in a series of systems for coordination among users of networked computers.  ...  We demonstrate, using a simple example, the requirements for the types of knowledge necessary in a automatic improvement framework.  ...

Understanding Object-Relational Mapping: A Framework Based Approach

Christopher Ireland, David Bowers, Michael Newton, Kevin Waugh, Bowers, M Newton, K Waugh
Here we show how that framework provides a mechanism to explore issues of fidelity, integrity and completeness in the design and implementation of an existing object-relational mapping strategy.  ...  Using our process we show how our framework helps to identify new issues, understand cause and effect, and provide a means to address issues at the most appropriate level of abstraction.  ...  The majority of the solution described in Table IX is possible using the objectrelational features introduced in SQL:1999 ("OR-SQL").  ...

Frame-based method for customizing generic software architectures

Yu Chye Cheong, Stanislaw Jarzabek
1999 Proceedings of the 1999 symposium on Software reusability - SSR '99  
The overall objective of the work described in this paper is to create formal links between requirements for system families and the process of customizing a generic architecture during architecture-based  ...  It can be used together with other customization techniques such as inheritance (in Object-Oriented frameworks), table-driven techniques (in compiler-compilers) or parameterization.  ...  ACKNOWLEDGEMENTS This work was supported by National University of Singapore Research Grant RP950615. We are indebted to Paul Bassett for letting us use the Netron's product Fusion for this project.  ...

Deriving Production Rules for Incremental View Maintenance [chapter]

1999 Materialized Views  
We provide a facility whereby a user delines a view as an SQL select expression, from which the system automatically derives set-oriented production rules that maintain a materialization of that view.  ...  It is widely recognized that production rules in database systems can be used to automatically maintain derived data such as views.  ...  Views are useful for presenting different levels of abstraction or different portions of a database to different users. Typically, a view is specified as an SQL select expression.  ...

Context in problem solving: a survey

Patrick Brézillon
1999 Knowledge engineering review (Print)  
We present in this paper a survey of the literature dealing directly and explicitly with context whatever the domain is. This permits us to have a clear view of the context in AI.  ...  Context appears in Artificial Intelligence (AI) as a challenge for the coming years as shown by the various scientific events focusing on context held since 1995.  ...  Leake (1992) considers the relationships between explanations and context in the framework of case-based reasoning.  ...

Using off-the-shelf middleware to implement connectors in distributed software architectures

Eric M. Dashofy, Nenad Medvidovic, Richard N. Taylor
1999 Proceedings of the 21st international conference on Software engineering - ICSE '99  
The relation of such services to software connectors in the context of software architectures, however, is not well understood.  ...  Modeling and implementing software connectors thus becomes a key aspect of architecture-based development.  ...  ACKNOWLEDGEMENTS The authors would like to thank Peyman Oreizy and Ken Anderson for their work on various aspects of the C2 style and, in particular, for their efforts in integrating Q with the C2 implementation  ...
