PHP, MySQL, Google Maps Questions

I'm attempting to build a web app and I've run into a bit of a wall. I'm not asking for anyone to hold my hand through making this, just some advice and a push in the right direction.

So, I'm trying to build an app that uses the Google Maps API to display a map of local parks near you and allow people to post pickup games (informal sporting events) for a specific time at a specific park. Simple enough right?

So far I've created a database with a table of local parks (columns: name, longitude, latitude) and a php script that takes that table and turns it into an 开发者_如何学JAVAXML file that the map uses to plot the points of the parks. I've also created a form that uses php to insert new data into the table and thus create a new park marker on the map.

This has all gone well so far but I'm just not sure how to proceed. I think I want to create a table 'games' (columns: sport, time, park(?)) but I'm not sure if that will work. Will I be able to setup a relationship between the 'parks' and 'games' table so that many games belong to a park? If so, how would I map those games? Does my thinking make sense?

If you'll create games table with sport_id | time | park_id columns, then game entity will be related to park entity by one-to-many relation. It means that one park handles 0..Many games and one game always belongs to one park.

So, this is suitable solution for your issue. It fits your expectations.
