You can restrict user from entering to much information by using 'Number of characters validation'
In this blog post I will tell you how to use the Number of characters validation option.
This option has three parameters (Is, Minimum, Maximum).
We'll take an example form "Leave you comment/opinion/feedback".
1. Create new project "Validation"
2. Add "Comments" field with a Multiple Line type to a new form "Example form". Open field for Editing and at the bottom you'll see 'Validation' link.
3. Open "Validation" tab and enter number of characters or minimum/maximum values.
So, you know how easy it is to create a simple database with QuintaDB.
