An introduction to the module and its assessment mechanisms. Also, the key sources for general context.

Position patterns in a continuum of Software Engineering knowledge. Explore contrasting definitions of patterns and introduce a definition of patterns appropriate to this module.

Plunge into patterns by looking at an example problem/solution. Attempt to characterize the nature of a pattern in concrete terms.

Create an abstract class that implements a procedure using abstract methods. These abstract methods must be implemented in derived classes to actually perform each step of the procedure.

Have the class that uses the algorithm contain a reference to an interface (or abstract class) that has a method specifying a specific algorithm. Each implementation of the interface (or derived class) implements the algorithm as appropriate.

Review the Template Method and Strategy Patterns in the context of a simple problem.

Xtend is a good representative of a language exhibiting more modern approach to typing. We review it here and discuss its main features.

Explore the same problem in Xtend. In particular, review how the Xtend 'lambdas' mechanism can simplify the solution significantly.

Encapsulate a request as an object facilitating the parameterization of clients with different requests, queuing requests and the potential support undoable operations.

Pacemaker reimplemented to incorporate the command pattern. This version is more sophisticated than the previous version - we model it here to get a general understanding of its structure.

A stream provides an interface to a sequenced set of values of a specific element type. “Lambda” = “closure” = record storing a function (functionality, method) and its environment (but without a class or method name)

Introduction to IT Architecture (ITA) and the need for ITA Styles and Patterns to build Enterprise Software Solutions (ESS). Review of the course structure and objectives for the coming weeks.

Explore an example of an Enterprise Application Systems (EAS) whilst investigating the recurrent characteristics of EAS.

Define Enterprise Application Architecture (EAA) and review it's purpose.

An Introduiction to Styles and Patterns within the Enterprise Application Architecture (EAA) domain.

An Introduiction to Analytical Frameworks in Architecture and the most common notations for modelling.

This session will define Architecture Views, explore their purpose and present View modelling techniques.

This lecture will define the term Architecture Perspective and discuss it's purpose within the context of example system abilities.

This lecture will introduce an Architecture Description (i.e. a document authored by an Architect) and discuss it's content and purpose.

An Architecture Description template (TOGAF 9.1).

This lecture will introduce an Architecture Modelling using Archimate 2.1 and provide examples of modelled sustems.

This session will discuss Architecture Principles with an emphasis on the fundamental design attributes of Coherence, Cohesion and Consistency.

This session will discuss application-driven and data-driven Architecture Styles.

This session will discuss Architecture Patterns with an emphasis on messaging, service, presentation and domain patterns.

This session is about sharing grounded experiences, common mistakes, advice and best practice in Architecting Enterprise Solutions
