In today’s world almost everything becomes online with the help of internet. We resides on online tools for most of our daily needs. We are using internet based applications to order foods, groceries, medicines, to shop online, to transfer money, to stay connected with our loved ones and the list goes on. Though these applications are designed for different purposes, all of them have a common phenomenon called DATA. Data plays a vital role in this internet era. This blog briefly discuss about what is data, different types of data available, necessity for storing data and DBMS.
What is Data?
Generally speaking, all things we observe in our day to day life is a data. Data is nothing but a information we get to know from a object or event that we come across. For instance, when meeting a person for the first time, we will share information like name, age, mobile number etc. These informations that we are exchanging is data. In digital world, data can range from the social media post that we upload to the image collected by nasa’s Mars rover. Process of collecting those data, organizing and managing them is called Data Management.
Why to store data?
Main purpose of storing data is to use it in future and use it whenever required. Single data can be utilized in many way. To achieve this we have to store the data. By nature we have our own Database, that is our Brain. Our brain will store data about our family, friends, school, office and almost everything that we come across and use them whenever required. Without this data store, we can’t even remember who we are. Similarly for an organization it is important to store it’s data to keep the business going. For example a online shopping tool should store it’s customer account detail, product detail, seller’s detail to efficiently run the business. This requirements drives the need to store data.
Types of Data:
Data is classified into three types based on the form in which it is available.
· Well structured
· Semi-structured
· Un structured
Database Management Systems:
We can store and retrieve data with the help of Database management systems.
DBMS acts as a bridge between user and data. DBMS is responsible to store data and make it available when requested. Generally data is being stored in data files in our system drive. These files are created and managed by DBMS. When we run a query to get data from DB, DBMS makes plan to get that data from the underlying DB.
In further blogs we will have a deep dive into types of data based on its form, various DBMS to store and manage them and how to shape them based on requirements.
