Title: Master/Magister thesis: Model-checking transaction properties for concurrent real-time transactions in UPPAAL
Subject: Computer Science
Level: Advanced
Description: Traditionally, a Database Management System (DBMS) maintains data consistency by ensuring the Atomicity, Consistency, Isolation and Durability (ACID) properties during transaction execution. In real-time systems, however, ensuring full ACID may not be desirable or possible, since transactions need to complete before their deadlines. Therefore, in real-time database management systems (RTDBMSs), ACID properties are often relaxed in favor of the timeliness of transactions. A systematic method to compute the trade-offs between ACID and timeliness is needed for developing the transaction management mechanism.
This thesis is intended for Master/Magister students in Intelligent Embedded Systems. The work of this thesis will be part of the DAGGERS research project. The goal of this thesis is as follows:

  • to model the transaction with associated concurrency control mechanisms (e.g. two phase locking, OCC, OCC-TI) in UPPAAL;

  • to specify formally the requirements of the created model as TCTL properties, by applying specification patterns for transformation;

  • to simulate and model-check the resulting model against the formalized requirements;

  • to produce a report describing the method, model and model-checking results.
