Most efficient way to store thousand telephone numbers
...ounts and each count is at most 1000. If we omit the last one (because we know it is 1000 anyway), we can store all of these numbers in a contiguous block of (2^m - 1) * 10 bits. (10 bits is enough for storing a number less than 1024.)
The last k bits of all (reduced) phone numbers are stored conti...

What is the recommended approach towards multi-tenant databases in MongoDB?
...o use a relational database. My data is quite unstructured, however, which now has me investigating NoSQL dbs like MongoDB.
