    <p><a href="http://redis.io/" rel="noreferrer">Redis</a> is a key-value storage system that operates in RAM memory, it's like a "light database" and since it works at RAM memory level it's orders of magnitude faster compared to reading/writing to PostgreSQL or any other traditional <a href="http://en.wikipedia.org/wiki/Relational_database" rel="noreferrer">Relational Database</a>. Redis is a so-called <a href="http://nosql-database.org/" rel="noreferrer">NoSQL</a> database, like <a href="https://www.mongodb.org/" rel="noreferrer">Mongo</a> and many others. It can't directly replace PostgreSQL, you still want permanent storage, but it works along with Relational Databases as an alternate storage system. You can use Redis if your IO operations start getting expensive and it's great for quick calculations and key-based queries.</p> <p>You can include it in your Django/Python project with a wrapper, for example <a href="https://github.com/andymccurdy/redis-py" rel="noreferrer">redis-py</a>.</p> <p>Redis is very simple to install and use, you can check the examples at <a href="https://github.com/andymccurdy/redis-py" rel="noreferrer">redis-py</a>. Redis is independent from any Relational Database, that way you can use it for caching, calculating or storing values permanently and/or temporarily. It can help reduce querying to PostgreSQL, in the end you can use it the way you want and take advantage from it to improve your app/architecture.</p> <p>This similar question can help you <a href="https://stackoverflow.com/questions/3801379/how-can-i-use-redis-with-django">Redis with Django</a></p>

    1. COthanks for the quick reply! How would I use it with PostgreSQL? See, my confusion in all of this is how the app will work. Will Django pull information from Redis which pulls information from Postgresql? If so how does it pull that information?

Querying!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
