ImmutableDB

An interface for immutable databases

ImmutableDB is an abstract interface for content-addressed databases that:

save the same blob of data to the same key every time (write)
return the same blob of data with the same query key every time (read)

The difference to a a traditional key-value store is that the key doesn't get specified explicitly. Instead, the key gets calculated based on the data using a hashing function. This is also called content-addressed storage.

Software Development Process and Managing It

Introduction

We're growing in terms of team and the product
We're moving from "prototyping" to "production" --> our needs change
Need to shift our mindset to "delivering"
Need a way to manage all the 1001 endeavours we have
