Keletak keletuk regarding IT part III

See, let's move on to proceed with more chapters okay?

Chapter 6 : Everything and everywhere is talking about information. Do you know what information really means? Well in IT also have information and by learning IT I am able to know the real meaning of information. Information are obtain by level, present by formats and differentiated by granulities. Besides info also has its own characteristics to show it is a quality info. Quality information must be accurate, timeliness, uniqueness and many more.

Chapter 7 is about where to store our valuable things. So where? In a saving box? Or a room with lotsa keys? In context of IT, place to store the information regardless what info in terms of any entity is called DATABASE. In a database it can store many information about various types of objects (inventory), events (transactions), people (employees), and places (warehouses). 

What I understands in this chapter is data warehouse consist of datamart and the process of transferring the data called ETL. ETL also transforms the information using a common set of enterprise definitions, and loads the information into a data warehouse. Similarly like us, a data warehouse need to be scrub and clean. It is to ensure that all the unwanted information or data is dispose from the system.

Last chapter of the day would comment on how to make decision? It is the toughest part of everything I must say. So for this, decisions must be made quickly and people need to analyze whether the info is large or vice versa. Decision making is important in organisation as if we decides wrongly, it would leave us with a high impact and could make us fall too.
