Features and Functions of SIMS Liam Hewer Systems Unit 3 - Information Features of SIMS Data Data requires implementation into an Information System to allow for processing and management. Once data is processed, it it information. Information is the ‘output’, with data being the input. Data is formed by each faculty when any information is input into SIMS. The quality and accuracy of information depends on that of the data. Hardware Hardware used within Information Systems must be able to process large quantities of data, and must also be compatible with the software used. Within the school, all the teachers laptops run on Windows XP-7 and therefore are compatible. Hardware must be kept at a correct update, usually the most recent update. Software The software is the link between the teacher and the database within the Information System. The software used (SIMS) is used across thousands of schools in the UK. It is used because it has the ability to enable teachers to input correct data and it can perform many different types of analysis upon the data to produce relevant reports and structured information. People The information outputted by SIMS is expected to be reliable, this is entirely dependant on the data input. Most errors caused within SIMS are down to human error. Staff are given instructions and are taught how to use the software before use to ensure all input are as accurate as possible. With no instruction, the user will be entirely inefficient. Telecommunications All output information created is shared between teachers. This can be via the SIMS software or via E-Mail. Through both these methods of communications, information can be sent around. For example, one students register for the day is sent from teacher to teacher, one by one inputting information into a certain field. It is important that all telecommunications flow well and correctly (i.e. to the right place). Functions of SIMS Input A user of an information system will input data. The system will store, process and eventually produce information using the initial data input. The user must specify what the input is for and what they want it to produce. Storage Data is typically stored within hard drives in the context of information systems. These hard drives are collected together to form a server where all data is stored. This can be accessed by authorised clients with connection the the server. Processing Processing is the function of the system that transforms raw data into information. Processing can vary in complexity. Simple processing would be addin the number of pupils in a class. Complex processing would be using statistics and other information to predict events or fill in blanks within banks of information. Output Output is generally split into two forms, graphical or textual. Graphical involves graphics, such as graphs, charts and other visual ways to arrange data. Textual provides statements summarising the data or providing a numerical table. Control/Feedback loops A Control or Feedback loop allows an information system to use the information produced to influence what happens to the next set of data. For example, if a student is marked ill in first lesson, the system will automatically mark every following lesson for that student as ill. Meaning that output information has an effect on the next set of output information. Open Systems Open systems wholly monitors amd interacts with it’s environment, this means it can adapt output depending on a range of internal and external variables. This is important in an Information System like SIMS, as it is accessed by 100+ individuals every hour, meaning that new input and editing occurs a lot and the system is able to update output using new data. Closed Systems Closed systems are much more basic than open ones. They don’t interact with very much at all. They don’t interact with new data very often and very rarely adapt output. It’s action are predicted and will just repeat a basic process. This could be something like the school bell ringing at set intervals in the day.
