Supporting Security and Consistency for Cloud Database [chapter]

Luca Ferretti, Michele Colajanni, Mirco Marchetti
2012 Lecture Notes in Computer Science  
Moreover, our proposal guarantees data consistency in scenarios in which independent clients concurrently execute SQL queries, and the structure of the database can be modified.  ...  Combining encryption with SQL operations is a promising approach although it is characterized by many open issues.  ...  In this context, let us consider that clients A, B and C are concurrently accessing the database: - Concurrent Operation Management The support to concurrent execution of SQL statements issued by multiple  ...

Book Review

Dan Nagle
2011 Scientific Programming  
We want to be able to code our concurrent algorithms in a form readable by mortal humans, using standard features of programming languages, that avoid the correctness and performance issues concurrency  ...  We also discuss functional lan-guages from a concurrency vantage point. We need arrays as first class objects to proceed, alas, lacking in the C family of languages.  ...

The Non-Deterministic Path to Concurrency – Exploring how Students Understand the Abstractions of Concurrency

Filip STRÖMBÄCK, Linda MANNILA, Mariam KAMKAR
2021 Informatics in Education. An International Journal  
In this paper we aim to explore how students' understanding these abstractions by examining 137 solutions to two concurrency questions given on the final exam in two years of an introductory concurrency  ...  One reason for this may be due to the fact that abstractions used in concurrent programs leave more situations undefined compared to sequential programs (e.g., in what order statements are executed), which  ...  (c) Use suitable synchronization primitives to solve the issue based on the critical sections you found in (b).  ...
