Prof. Raju Halder, IIT Patna
Date & Time: August 13, 2015 15:00
Venue: Conference Room, C Block, 01st Floor, Department of Computer Science and Engineering, Kanwal Rekhi (KReSIT) Building
Abstract:
In this talk, we describe the abstract interpretation of Database Query Languages and its various applications. We formalized a complete denotational semantics, both at concrete and abstract levels, of database applications instrumented with data manipulation language operations such as SELECT, UPDATE, INSERT, DELETE. The theoretical formal framework serves as a foundation of several interesting practical applications, e.g. fine grained access control of data, persistent watermarking, cooperative query answering, etc. In this direction, the issue of semantics-based dependence refinement in database language is also addressed which leads to a more precise analysis of database applications, including program slicing, language-based information flow security analysis, etc. The semantics-based analysis of Hibernate Query Language this way leads to a formal verification of persistent object’s properties as well.
