Build a hotel search engine from scratch in Java

Question

Hi, I would like to build a hotel search engine in Java from scratch. It should be able to get data from different websites (expedia booking etc), store this data and as soon as a user types in his preferences this data should be used to give him results. so how do I start?

Answer 1

If you only have to do only back-end works, then start from scratch will give you throughout understanding of search engine and can give you more control of your code. It will be very helpful.
But more works ( lone-wolf developer? ) need more time, right? So, if i don't have to meet project dead-lines or so, I would go for starting from scratch option.

Answer 2

You will need to know front-end (gui or website or something that user will interact), back-end (To query result from storage database), and database (To store your data from different sources).

Answer 3

@Sylar thanks, but this is basically valid for any app. what I am interested in is your backend point. I would like to write code as already described. I guess a hotel search engine works like any other web crawler, right? could I start with open source web crawler and try to change it like I would like to have it or would you start from scratch, only loosely work with open source (like crawler4j)?

thanks for your input🙏
