3.2 Systems Flashcards
Corporate information system (CIS)
Def: A fully integrated, company wide system (1) that aims to meet all organisational ICT requirements at all levels (1)
Ex: All systems in the company access and update the same data source (1) E.g. Personnel data is used by different departments. (1)
Back office system
Def: Back office systems run the internal operations (1) of an organisation and are not accessible or visible to the general public. (1)
Ex: An example of a back office system is Accounts. (1)
Transaction Processing systems
Def: Transaction processing systems carry out the day to day activities of most organisation at an operational level (1) These systems might deal with commercial transactions such as customers buying tickets or paying bills (1) and others involve receiving data such as making bookings, enrolling students etc(1).
Ex: As transactions are carried out the database records are updated before another transaction takes place (1) for example when multiple users are using a flight booking system as a seat is booked, the number of available seats is reduced (1)
Workflow management system
Def: software that helps organisations analyse and manage business processes (1) and identify possible problem areas that are slowing down the information flow (1) which may affect the efficiency of the organisation.
Ex: In a call centre workflow management lets managers define activities and allocate staff to them(1) Workflow management systems use databases and networks so each user is given access to the data they need at exactly the right time (1) If a workflow management system identifies a bottleneck or any other problems, Managers can re-allocate team members to do different jobs(1)
Workflow systems often include document management systems
Document management systems.
Def: Used to store paper based documents electronically (1). Documents were scanned and stored as image files, with keywords, authors and other data similar to a library system (1) which are easy to search for (1) links can be set up making it easy to cross-reference between documents (1)
Ex: Some organisation (e.g. insurance companies) receive paper documents in many different forms DMS is used to digitise them by scanning them in and organising them
Systems for collaborative working
Def: These enable teams to work on one project or activity at the same time (1) Collaborative systems allow parts of the project to be “locked” while individual team members work on that part (1)
Ex: An example could be where developers are working on systems documentation: while one developer is updating a document, others can read it, but not update it(1).
Management Information Systems (MIS)
Def: Management Information Systems (MIS) convert data from internal and external sources into information (1). It is then communicated in an appropriate form for managers at different levels to make decisions (1)
The data that is produced by the lower levels of the organisation all feeds into the MIS, is summarised and presented in forms that are easy for managers to interpret
Ex: For example, the bakery manager in a supermarket chain may require details of past seasonal sales details in order to determine order levels (1).
Decision support systems
Def: Decision support systems are high level management information systems used by senior managers to make strategic decisions(1).
Ex: For example, the Board of a supermarket would require information about competitor activity and likely potential customers before making the decision to open a branch in a new area.
Enterprise systems
Def: Enterprise systems are most often seen in large and medium sized organisations and aim to overcome the difficulties caused by different systems being run in different departments (1).
Ex: Typically an enterprise system is based on a very large database and is used to integrate all key business activities (1) such as sales, accounting, human resources, inventory (stock control) etc
Data mining techniques are often used to look for hidden patterns in the data that may be useful and not immediately obvious
Customer Relationship Management.
Def: Customer Relationship Management system records details of all transactions and contacts made with a customer (1) and stores information about them in order to improve the service that a customer receives (1). CRM software stores the customer data centrally so that the up to date information is available to all departments (1)
Ex: Loyalty card systems used by retailers are an example of a CRM system. (1) When purchases are made the customer presents the loyalty card and the CRM systems accumulate points or credit. The customer data is used to analyse shopping habits and often used to identify “target” customers and for trend analysis
A data warehouse can be used to store the vast quantities of data generated by enterprise ECRM systems
E-commerce systems
Def: E-commerce systems are designed to support the buying and selling of goods and services online (1)
Security of online transactions is vital and a cause for concern for customers so secure servers are setup for financial transactions and display https instead of http with a padlock symbol
Ex: systems used for online sales, ticket reservations, licence applications etc
E-commerce systems with back office integration
Def: This is when online e-commerce systems are linked with back office systems. So, when a customer places an order, the online system accepts the order then transfers the information back to the customer while the back office automatically records the transaction, recalculates inventory levels and generates the invoice
Payroll
Def: A payroll system calculates the amount that is owed to employees based on factors such as the time they worked, their hourly wages or salaries.
Ex: Payroll systems carry out tasks that include keeping tracking of hours, calculating wages, withholding taxes and deductions, printing and delivering payslips and paying tax and national insurance to the government.
Human Resources systems
Def: Human Resources systems can be used to record personal details of all staff , including start date , qualifications and training and past employments and experience. Some HR systems are also combined with payroll packages.
Stock control
Def: A system that makes sure that the correct level of stock is maintained to be able to meet demand while keeping the costs of holding stock to a minimum Stock control systems help you to: Know how many items of stock you have When to re-order replacement stock What is selling well What is selling badly What is getting out of date
Linked to purchasing systems, accounting, sales, JIT etc
Can be used to manage internal resources (unit 3.12) such as ICT consumables (i.e. printer cartridges, paper) and is necessary for efficient management of consumables
