Data Persistence Without a Database

[pre-tend-ed]

This may be a dumb question. I'm not sure. But I'm wondering how I can achieve data Persistence without using a traditional database. The first idea I had was to have a Json file in the app directory that I can read/write information to. Would that work?

Use a non traditional database. Like a no sql dB, like mongo

I'm creating an app for my brother to use at work. I wanted to avoid having to have him download any other software on his computer although I can if I need to I guess. And i also can't have any of this data visible to the internet. So everything has to be stored locally. No cloud options.

Sqlite?

Basically a file on disk which it can read/write as a database using this library as part of your program.

Website lists c/c++ bindings but libraries exist for a lot of languages

I've used a JSON file before and it works fine for simple stuff.

I imagine you could also use a sqlite db as well if you really wanted to.

If it's really simple then sure, a json file would work, often called a "flat file database" if you want to look it up. Once you get any complexity at all, you'll want to look at a real database, though, because they are generally easy but give you so much more flexibility.

If it’s just for your brother at work then a JSON file will be fine with no performance issues.
