Why?

It could be useful for a firm for example, a factory that want to compare all of its products, it helps to classify them, and when a customer is looking for some characteristics, he may ask what he wants the product to do without knowing the product he really wants. Thanks to database, products would be classify and it would be possible to propose different types of products to the client, concerning the price, or the color for example. Also, for those who love a theme, especially there for film-lovers, if they want to classify movies concerning their duration or their type (romance, horror…). There, we have a capture of an example we saw in the course.

The project: The project is to help individuals that love wine. First of all, we need to create a database dealing with wine. Our database should look like this:

Every single wine need to be entered in the base with some categories: color, value for money, vintage…

Now, we can deal with our database thanks to Glitch.

 

Finally, we just have to create a box to enter what we are looking for. It is possible to do it using Skeleton. We can ask in the box to find a red wine from 2019 which cost is less than 10euros and that will perfectly match with fish. Skeleton helps to optimize websites, and in particular let possible to create boxes.
