Introduction to Database Types
In the context of this course, data is raw digital information, like the data stored on computer hard drives and the internet.
What is Analysis?
It is defined as the process of data cleaning and transforming data to answer the fundamental question, “What is my data saying”. So, an organization can use insights to avoid pitfalls altogether.
Types of databases
The below figure shows the difference between the two types of database systems.
Figure 1.1, representing a structured database, and Figure1.2, representing a non-structured database.
Figure 1.1, a child’s toy box
Figure 1.2, a cardboard box
Now I would like you to think of this toy box, think of the colorful widget as data that would fit inside the box. Similarly, all structured databases have a structure associated with the meaning that they cannot accept all the different types of data.
Now think of the cardboard box, this box would allow you to fit any type of object in it as long it is within the capacity of that box in what-ever way stack it up like you like. So unstructured database, contain the data you would see in the wild like sound, data generated by IoT network, etc.
