Hai!!This is my second post and I would like to write about the first topic in IT which is Data, Information and Information Management. Firstly, let me introduce my lecturer before I write more about this topic. She is Miss Qairulnisha or as known as Miss Nisha. She is pretty, young, attractive, stylish and single. Actually I miss this lesson because I registered lately for foundation studies. I study this topic by myself. I will write what I understand about the topic.
Firstly we have to know what is data. Data is a raw facts and it doesn't has contextual.It can be in the form of numbers, text, video and even audio. Data is used as input of processing. Meanwhile, information is data with contextual.Information will processed, summarized, organized and analyzed data. Information is used as output of processing. This processing will become knowledge. Furthermore in this topic, we also learnt about data integrity.Data integrity is maintaining accuracy and consistency of data and it important for database or RDBMS system.
The most important in this topic is GIGO ( is the computer phrase). GI is garbage in while GO is garbage out. We cannot create information from incorrect data. When the poor garbage in become poor garbage out, the data integrity is lost.
Output or input is devices are used by a person to communicate with computer. Input is any data that is received by the system (into computer's memory).
Meanwhile, output is a data that has been processed to send it.Output devices will conveys information to one or others people.
We also learnt about Information Management or as known as IM in this topic. IM is information's collection and management from one or more sources and the distribution of that information to one or more audiences. IM encompasses systems such as web content management(CM), document management(DM), records management(RM), digital asset management(DAM), learning management systems(LM) and learning content management systems(LCM).
