Define columns in Microsoft Dataverse
Columns are a way to store a discrete piece of information within a record in a table. Columns have types, meaning that you can store data of a certain type in a field that matches that data type. For example, if you have a solution that requires dates, then you would store the date in a field with the type of Date. Similarly, if you want to store a number, then you store the number in a field with the type of Number.
The number of columns within a table varies from a few columns to a hundred or more. If you need more than a few hundred columns in a table, you might want to reconsider how you're structuring data storage for your solution because, likely, there's a better way.
Every database in Microsoft Dataverse starts with a standard set of tables and each standard table has a standard set of columns.
Tip
Always use standard tables and columns when possible. You can rename a table if that makes the table more understandable in the context of your solution. Always review the list of standard tables and make sure a standard table will not meet your needs before you create a new table.
