Firstly, I want to build the site myself. I just need help getting started as I have never used these frameworks before. Its important I learn for college Let me explain I have this PostgreSQL Schema, some of the tables are review, review_comment, review_sub_comment, review_like, review_share, review_rating, review_view Article, article_comment, article_sub_comment, article_like, article_share, article_rating, article_view preview, preview_comment, preview_sub_comment, preview_like, preview_share, preview_rating, preview_view app_user, match, ip_user - this non registered user when they load any article, review or preview cause there ip to create a ip_user, and create a view and can create a share. But cannot comment, rate or like. Clicking them buttons pop up a register div This is rough schema, there more and shared in database design The home page picks a random row from either article, preview or review and fill's the HTML page with its data, like header, text, views, likes, rating, comments and any sub comments for each comment. I want a basic set up structure so I can see it and how it works. I need to learn this stuff and would have a little boost towards it Here is what I have done so far https://spring-boot-jdbc-psql.herokuapp.com/ I'm using JDBC, try, catch to pull data and then model.addattribute it to html page and I have been told i should be using spring data. I hit brick wall when i needed comments and there associated sub comments I can give you access my project and PostgreSQL database views I can share project with you so far. I am hoping to get set on the right path How much do you think you will charge me to get this basic thing up and running with the elements above as described added so I may study it and learn about these frameworks
