Introduction This key skill develops your information literacy (IL) skills in your studies, work or other activities over a period of time. To tackle all of this section you will need to plan your work over at least 3–4 months to give you enough time to practise and improve your skills, to seek feedback from others, and to monitor and evaluate your progress. Information literacy is not the same as information technology. Information and communication technology skills tend to concentrate on using
Diagramming for development 2 - Exploring interrelationships
Diagramming for development 2 - Exploring interrelationships, is a free course that introduces you to the diagramming techniques of Influence diagrams, Multiple Cause Diagrams and Cognitive Maps. Using a case study project based in Africa, this unit illustrates the powerful use of systems diagramming for international development management. This is a companion course to Diagramming for development 1: bounding realities.

Successful IT systems
Information technology (IT) systems are a critical part of our world, in business and the public and voluntary sectors. They are often highly complex and interconnected combinations of technology, organisations and people. Success and failure of IT systems can be seen in many different settings. Many are highly successful; others fail, sometimes spectacularly. This free course focuses on success, to help you understand what is meant by a successful IT system.Author(s):

Systems thinking and practice
What is systems thinking and practice? The essence of systems thinking and practice is in 'seeing' the world in a particular way, because how you 'see' things affects the way you approach situations or undertake specific tasks. This free course will help you to learn about the problems of defining a system and meet some of the key concepts used in systems theory: boundary, environment, positive and negative feedback, etc.

9.1 What is a state machine? An event is an occurrence of a phenomenon at a certain moment in time. The occurrence of the event itself is assumed to have no duration. Typically, when an event occurs, it affects the state of an object. A state machine is a model of the behaviour of a single object over time and helps you to understand how that object's state affects its reactions to events. Figure 18 shows a state machine diagram (known as a statechart diagram in the UML) relating to the occupancy of a room in a hot
8.2 Example of a university registration data model Here is a statement of the data requirements for a product to support the registration of and provide help to students of a fictitious e-learning university. A UK-based e-learning university needs to keep details of its students and staff, the courses that it offers and the performance of the students who study its courses. The university is administered in four geographical regions (England, Scotland, Wales and Northern Ireland). Information about each student should be initially
8.1 Introduction One type of data model is an entity–relationship data model. Experience has shown that data can be best described by relationships between entities. An entity is anything of interest about which data is recorded, such as roads, weather stations, trucks and weather station readings in the IceBreaker project in the book MRP. In general, there will be many relationships (or associations) linking the entities. A trivial example is the fact that a given weather reading
7.2 Exercises Draw an activity diagram for the main success scenario for the check out guest use case. 6.13 Exercises Write down a textual description (using the format of Table 2, reproduced below) of the use case check in guest, shown in Figure 3, also below. As part of your deliberations, identify any exceptions t 6.11 Issues with use cases There can be a tendency to make diagrams too complex. You can reduce the complexity of your use case diagram by: redrawing it at a higher level of abstraction; splitting it up into smaller modules, which the UML calls packages. In the case of the hotel chain, we might partition our model into the following three packages: reservations; checking guests in and o 6.10 To extend or include? Whatever kind of system you intend to develop, you will need to consider its security. Usually, we allow only trustworthy people to use a new system. Therefore, in a software solution we can envisage a log-on use case, which describes how a user gains access through some authentication procedure. How should such a requirement be included in the example of the hotel chain? By analogy with natural languages, the UML allows a number of ‘grammatically correct’ options each of which will
