Abstract
Conference Title: 2018 9th International Conference on Computing, Communication and Networking Technologies (ICCCNT) Conference Start Date: 2018, July 10 Conference End Date: 2018, July 12 Conference Location: Bengaluru, India With the introduction of fundamental concept computational thinking, Block-based programming tools are turning into more and more common in primary, middle and high school level introductory classes. Block-based programming languages support users to drag and drop different jigsaw shaped blocks and snapping together to form a program. The point of interest is on the programming logic rather than its syntax. In this paper, we present DB-Learn, a browser-based and visual programming environment. This facilitates to learn the concepts of relational algebra concepts. Relational algebra is one of the important concepts to learn and understand the operations of database management systems.
