1.7 Testing The aim of testing is to uncover errors in the design and implementation of the database, its structure, constraints and associated user and management support. Testing is usually considered to involve two main tasks – validation and verification. Without adequate testing users will have little confidence in their data processing. Validation answers the question: has the right database been developed to meet the requirements? It attempts to confirm that the right database has been co
1.6.4 Supporting data management strategies Most of the development we've covered so far in this unit has focused on meeting specific user requirements – that is, ensuring the right data are constrained correctly and made available to the right user processes. However, other questions must also be addressed in order to support a data management strategy: How frequently should data be backed-up? What auditing mechanisms are required? Which users will be permitted to perform which functions? Which database tools and user processes wil
5.2.1 Transforming the natural to the designed The artist Christine Martell lives in Oregon in the United States and works with beads and visual images. I asked her to describe how she makes use of a computer to create her visual images of flowers and trees. She writes of her work: I start by finding flowers that are compelling in some way, most often in form and colour. I take photographs with a 35 mm camera having a macro lens. I'm usually looking for a 3.4.1 A computer system is the combination of: the computer (with its processor and storage); other equipment such as a scanner or printer, the software programs that make it all work (software programs that are designed to help with some human task are often referred to as applications). 2.2 The organisation: loyalty cards Many supermarkets and other firms (such as petrol companies and airlines) use loyalty cards: cards that offer a customer some form of incentive, such as a future discount or gift, to continue buying from that firm. For example, the British supermarket chain Tesco issues such cards. The holder of a loyalty card is regularly sent vouchers which give the holder discounts from their shopping bills and also vouchers which enable them to gain a discount on items that the supermarket wishes to promo 2.1 The individual: an average day If I take an average day in my life, I find myself surrounded by computers, most of which are invisible to me. This section looks at where computers are found in the course of everyday life. It aims to: place computers in the context of the activities we do and the things we handle in our day-to-day lives. But it does this from two points of view: the individual and the commercial organisation.

To learn to be creative and spontaneous in the language you are studying, you need to practise listening and speaking throughout the course and in revision.

These might be: short reports multiple-choice answers dif 3.10 Thinking about the exam It is worth noting the difference between exam answers and assignments. Inevitably, a much lengthier and more polished answer can be produced in an untimed assignment. In the short time available in the exam, you need to move quickly through your main points, without paying too much attention to your style. Examiners are fully aware of the constraints exams place on the writer. Focus on the question you have chosen, and underline or highlight the process words or instructions in the question. 3.9 Understanding process words
Your course might not include any maths or technical content but, at some point during your course, it’s likely that you’ll come across information represented in charts, graphs and tables. You’ll be expected to know how to interpret this information. This unit will help you to develop the skills you need to do this. This unit can be used in conjunction with the ‘More working with charts, graphs and tables’ unit, which looks into more ways to present statistical information and shows y
How does a child’s mind and behaviour change as they develop over time? In this unit four theories of child development are explored. Each theory views child development from a different perspective and all have underpinned psychological research for many years, and continue to do so today. By the end of this unit you will have a good understanding of each of the theories and will probably have begun to challenge your own assumptions about how your own children, or children you know, have deve
What is meant by ‘science’? How do political, philosophical and religious beliefs affect scientific discoveries and developments? In this unit you focus on your own experiences and knowledge of science, and you look at creative contexts to support children’s scientific learning in primary schools and early years settings. First
This unit introduces you to the theoretical toolkit that is an essential part of engaging in educational enquiry. You will consider the types of theories and what their role is in the research process. Two very influential research perspectives are examined to identify differences in ways we think about and study the social world.Author(s):
This unit focuses on higher level skills. Skills development is complementary to other learning – it cannot be done in isolation. The higher level skills in this material aim to raise your awareness of the processes of learning and development – other subject-based material must supply the context and motivation for this. Key skills underpin the ability to carry out successfully, and improve on, a wide range of tasks in higher education, employment and wherever there is a continuation of le
In this unit we will look at the meaning of policy, how it works as a mechanism of persuading people to behave in particular ways, its role in shaping our understandings of young people, and the role practitioners can play in mediating and influencing policy.
