Data Management for Relational and Non-Relational Data Bases


The main goal of the course is to teach students modern data management techniques for both relational and non-relational database systems. Topics such as: database design, database implementation, SQL language, physical storage and request processing, and optimization will be studied. Emphasis will be placed on both understanding the internal operation and architecture of modern data management systems and developing applications in a programming environment. Also, principles of distributed and parallel databases will be presented, as well as modern non-relational systems that achieve high efficiency and scalability. Through this course, students are expected to acquire important technical skills in large-scale data management and learn to design and implement applications that will manage huge volumes of data.
