Authorization analysis of queries in object-oriented databases [chapter]

Hiroyuki Seki, Yasunori Ishihara, Minora Ito
1995 Lecture Notes in Computer Science  
A simple model for method-based authorization is defined and an algorithm is presented for testing in compile-time whether a given database schema violates authorizations.  ...  A method body is simply a sequence of statements. There are three types of statements: an access to an attribute of the self object, a method invocation, and a built-in operation on basic values.  ...  Recently, various access control models for object-oriented databases (OODBs) have been proposed (see [4] , which is an excellent survey).  ...

BiQL: A Query Language for Analyzing Information Networks [chapter]

Anton Dries, Siegfried Nijssen, Luc De Raedt
2012 Lecture Notes in Computer Science  
One of the key steps in data analysis is the exploration of data.  ...  The BiQL data model consists of two parts: a data model describing objects, link, domains and networks, and a query language describing basic network manipulations.  ...  A more recent development is that of object-oriented database systems and query languages such as OQL (Object Query Language) [12] .  ...

A Comparison of Current Graph Database Models

Renzo Angles
2012 2012 IEEE 28th International Conference on Data Engineering Workshops  
In this paper we present a systematic comparison of current graph database models.  ...  The limitations of traditional databases, in particular the relational model, to cover the requirements of current applications has lead the development of new database technologies.  ...  Additionally, and considering that graph databases are oriented to store and query graph data, we evaluate graph databases in terms of their support for querying a set of essential graph queries.  ...
