Information is not useful if not organized. In database, data is organized in a way that people find it meaningful and useful. Database Management System (DBMS) is used to input, sort, organize and store data.
Database Management System (DBMS) is a Software for data storage & retrieval, for creating user interface (forms), reports, and for administering a DB system (security, access, etc.). An implementation of a DBMS product to support various information needs in a company includes one or more databases, logic (business rules), backend code and user interface.
An information system that is built from “applying” a DBMS or a database to a specific domain, supports specific information needs.

Had a great experience with the course, the classes touch upon both the functional and theoretical aspects of programming, and the care in responding to questions as well as obvious dedication to continue updating and improving the course are very motivating.
Very professional. Honestly, this is about 2 courses worth of python in 1 course (in my opinion). Good pace, clear content, builds on each topic.
This course was one of few courses in python which i took. I must say nothing was more comprehensive and exhaustive like this. Attitude Academy goes into each and concept and talks about it in detail. At times it was overbearing but if you are able to complete it - you would have got valuable insights into the dynamics of python. I use this material as a reference. I am glad that i took this course! Thank you guys
