# Creating a Definition
Definitions are an essential concept for manipulating and analysing data within the CoB platform. By allowing us to make in real-time any changes deemed necessary, they enable us to quickly adapt the platform to our business needs. You can create a definition by adopting one of the three following approaches:
- Manually create all the definition fields;
- Copy the definition fields from an Excel file;
- Import the data records from a exported Excel file.
