You are trying to prototype a website fast, to show something to a potential customer. You are using Heroku or C9 or any other similar platform. Then you have to lose some time configuring a database, just to pupulate it with a few data to show to your customer.
Wouldn't you like to have a tool to make this database task easier?
If so, now you have it!
TxtDB is a Ruby gem that implements all you need to have a small textfile-based SQL database, ideal for fast prototyping.
It is part of a suite of tools I'll be publishing this December to make the lives of Ruby on Rails developers easier.
Time is money. Or at least so they say. For me, time is something I may spend with my family, my friends, my books... Why spending it with tasks you may avoid?
