# Data connection

Marple Insight visualises data by directly connecting to a team's database. This approach ensures that users can analyse measurements without needing to duplicate or migrate data. 

Setting up a connection is simply a matter of providing the necessary credentials and configuration details so that Marple can identify:

* a list of **data sets;**
* within each data set, a **signal list**;
* for a given dataset, signal and time range, **time series data**;
* within time series data, a **segment list.**
  * a segment list is optional, but incredibly powerful in use cases such as motorsport (laps) and flight testing (flight phases) (see [Motorsport Package](/docs/marple-insight/user-manuals/motorsport-package.md) and [Flight Testing Package](/docs/marple-insight/user-manuals/flight-testing-package.md))

We have developed a dynamic system that is designed to work with multiple database types, supporting a variety of use cases.
