# Let’s talk about complexity in TM1

Big Data is a big buzzword at the moment, so I thought it would be interesting to explore how “big” data can really get. What happens if we examine a TM1 system, and calculate the number of values that could be theoretically stored in it?

From experience, we know that most cells in a cube will not contain a value, or in technical terms, cubes tend to be sparse, but let’s ignore that for a moment.

What would be your guess on where the biggest customer in our Pulse Benchmark Database ended up ? As it turns out, the biggest system in our benchmark database was submitted by a Cubewise customer in Sydney, who has a cube in their TM1 model that can store a massive number of values, specifically:

**23,623,343,580,973,000,000,000,000,000,000,000,000,000,000,000,000,000,000,**

**000,000,000,000,000,000,000,000,000,000 **

**( Note that I had to insert a line break so the number could fit on the page!)**

This is such a big value I didn’t know how to read it out loud, so I asked Wolfram Alpha what it was called. The official English name of this number is:

**23 septenvigintillion 623 sexvigintillion 234 quinvigintillion 580 quattuorvigintillion 973 trevigintillion**

or, if your background is more scientific you might write it as:

**2.36 x 10^85**

This certainly seems big, but a physical comparison will give you some perspective on how really enormous it is. **This cube has more cells than the visible atoms in our universe, which is just around 10^80.**

In everyday business, astronomical numbers like these are not very important to an end user or developer, but this experiment demonstrates a few things:

- TM1 can model very complex applications that are not possible with other technologies
- Even a system of this size retains the ability to perform real-time calculations and modeling while effectively serving many areas of the business
- Pulse for TM1 helps you document, manage and support an environment like this, and enables you to scale TM1 applications to arbitrarily large sizes and complexity
