Databases: Journal 1

1.  Relational database and spreadsheets on the surface may seem similar, however, there are some key differences that cannot be ignored. For one, a relationship database has a primary key that is unique to identify and programmatically fetch data, spreadsheets do not have this. Another differences are when it comes to columns, in a spreadsheet, columns can have any data and do not have to be uniform, this is not true in a relational database where all the columns have to be uniform.
2. Using a relational database allows us to programmatically pull and update data, without being able to do this, it would be really difficult to have a uniform way of changing data since files can be arranged in a different manner that is not always uniform. Additionally,  relational databases help us create relationships between data.
3. I mostly want to learn the inner workings of beautiful front ends that we see in applications today. How all that data is stored and then retrieved in a elegant way through programming.
