I want to have an open source web application all on one VPS. I will use Linux, Apache, and PHP. I want the database to store locations (addresses in the USA). There will be a program that will search the addresses in the database. I do not want to spend money on licenses. The data will be updated weekly. The schemas and tables should not change that frequently at all.
Strong data types are optional.
I am going to set it up myself.
What open source database product should I use for my project?
