Software Development Life Cycles and process models

This presentation describes the evolution of SDLCs from the first formally proposed linear models including, the Waterfall (Royce 1970) through to iterative prototyping models (Spiral and Win-Win Spiral) and incremental, iterative models used in Agile Methods. We discuss the problems iinherent in ech prpoosal and how successive models attempt to solve them.

Software Development: Testing

This presentation discusses the role and purpose of testing in the systems/Software Development Life Cycle. We examine the consequences of the 'cost curve' on defect removal and how agile methods can reduce its effects. We concentrate on Black Box Testing and use Equivalence Partitioning and Boundary Value Analysis to construct the smallest number of test cases, test scenarios necessary for a test plan.

The Web 2.0 Development Survival Guide

Building software for Web 2.0 and the Social Media world is non-trivial. It requires understanding how to create infrastructure that will survive at Web scale, meaning that it may have to deal with tens of millions of individual items of data, and cope with hits from hundreds of thousands of users every minute. It also requires you to build tools that will be part of a much larger ecosystem of software and application families. In this lecture we will look at how traditional relational database systems have tried to cope with the scale of Web 2.0, and explore the NoSQL movement that seeks to simplify data-storage and create ultra-swift data systems at the expense of immediate consistency. We will also look at the range of APIs, libraries and interoperability standards that are trying to make sense of the Social Media world, and ask what trends we might be seeing emerge.

TIDT's Development Process

This presentation gives an overview of TIDT's development process at time of writitng in March 2016. We were and still are developing our process. It is an agile process based on DSDM and Scrum.
