What social, ethical and economic issues arise from automating manufacturing, and what are the emerging trends?
Describe the social and ethical issues raised by automated manufacturing systems, including the changing nature of work, retraining, safety and the environment, and emerging trends such as additive manufacturing and smart factories
Core: Communication Systems
Module overview →What are the functions of a communication system and how do protocols make communication between devices possible?
Describe the functions performed within a communication system and the role of protocols and handshaking in transmitting and receiving data
How do real communication systems such as email, messaging, the internet and EDI carry out the information processes?
Describe examples of communication systems, including email, instant messaging, the internet and the web, electronic data interchange and teleconferencing, and how each transmits and receives information
What security, privacy and social issues arise when information is communicated across networks?
Describe the social and ethical issues raised by communication systems, including message security and encryption, privacy of communications, the effect on work and society, and the digital divide
How are networks structured and what media and methods are used to transmit data across them?
Describe network topologies, network types and transmission media, and compare transmission methods used to carry data between devices
What functions must take place for a message to travel from a source to a destination across a communication system?
Describe the communication framework as the functions performed when transmitting and receiving data, including message creation, organisation, control, addressing, transmission, synchronisation, error detection and decoding
Option: Decision Support Systems
Module overview →How do data warehouses, data mining, OLAP and expert systems extend a decision support system?
Describe data warehousing, data mining, online analytical processing, expert systems and group decision support systems, and how they analyse stored data to support decisions
How do decision support systems help people make decisions and what tools and models do they use?
Describe the characteristics of decision support systems, including modelling, what-if analysis and the tools used, and compare them with expert systems
Core: Information Systems and Databases
Module overview →How do information systems collect, analyse and display data, and what technologies support these processes?
Describe how collecting, analysing and displaying are carried out in database information systems, including data validation, querying and reporting, and the hardware and software involved
How are relational databases structured and how is data retrieved from them using SQL?
Describe the organisation of a relational database into tables, records, fields, keys and relationships, and construct SQL queries to retrieve and manipulate data
What social and ethical issues arise from large database information systems and who is responsible for them?
Describe the social and ethical issues raised by database information systems, including privacy, data accuracy and quality, data ownership, control, and the impact of centralised data
How is data organised for storage and retrieval beyond the relational database model?
Describe non-database methods of organising data, including flat files, hypermedia and free text retrieval, and the storage and retrieval methods used by information systems
What are the seven information processes and how do they describe what an information system does?
Identify and describe the seven information processes (collecting, organising, analysing, storing and retrieving, processing, transmitting and receiving, displaying)
How do information systems physically store data and retrieve it efficiently, and how is it kept safe?
Describe the storing and retrieving information process, including online and offline storage, indexing, the role of the schema and data dictionary, backup procedures and encryption
