Object-Oriented Information Systems

1. Critical understanding of Information Systems Design: Demonstrated through the appraisal and evaluation of the concepts and principles of information systems, specifically discussing a number of information systems failures.

2. Understanding Object-Oriented Design Principles: Demonstrated by discussing and documenting an object-oriented information system using appropriate tools, like UML diagrams.

3. Designing and Object-Oriented Information System: Demonstrated through the design of an object-oriented information system based on a number of business requirements, using UML diagrams and design documentation.

4. Object Oriented Development: Demonstrated through the implementation of an object-oriented information system design, using Python and SQL to produce "Marketplace", a Flask web application.

Object Oriented Information Systems - UML Class Diagrams: My initial attempt to produce a class diagram for a supermarket, and my thoughts on the usefulness of UML and the difficulties I encountered in the process.

Alternatives to SQL: A short post on the advantages presented by MongoDB, a document-oriented NoSQL database.
