The main topics covered by the module are: the principles and components of database management systems; the main modelling techniques used in the construction of database systems; implementation of databases using an object-relational database management system; the main relational database language; Object-Oriented database systems; future trends, in particular information retrieval, data warehouses and data mining.There are two timetabled lectures a week, and one-hour tutorial per week (though not every week). There will be timetabled laboratory sessions (two hours a week) for approximately five weeks.ResearchResearch Interests:My research focuses on three related areas:1. information retrieval (IR) models and probability theory2. integration of database (DB) and IR technologies3. DB+IR+AI technology and advanced statistics for data scienceIR models are related to probability theory and the sound derivation of IR models leads to new and general approaches to rank any object, to reason about complex knowledge sources, and to make decisions. Many results of my research over the past 10 years are summarised in the book "IR Models: Foundations and Relationships", Morgan Claypool Publishers, 2013. Currently, my main research interest is in generalisations of probability theory in order to obtain a "new" theory that joins probabilistic and information-theoretic reasoning (logic).The integration of DB and IR (and AI) is an ongoing research challenge, though, in principle, DB and IR do the same: manage and retrieve data. I have developed probabilistic object-relational, logic-based knowledge representations that are useful for solving tasks in the domain of "semantic" (knowledge-rich) information management tasks. This led to POOL (a probabilistic object-oriented logic) based on AI knowledge representations, and the "Relational Bayes", a patented technology (VLDB Journal 2008).Both, probability theory and DB+IR+AI technology produce methods and tools for solving complex data science tasks.Based on the insights into probabilistic reasoning and IR models, and a seamless DB+IR+AI technology, we apply a probabilistic Datalog engine in data science scenarios (data analytics, complex search).Publications
