Hello Michael,


It is totally dependent on the DB that you are using which will create the columns in the table as much as the attributes you define in the entity, for example-

https://www.postgresql.org/docs/current/limits.html



For oracle-

There's a hard limit of 1,000 columns per table in Oracle Database 


For SQL Server-

https://learn.microsoft.com/en-us/sql/sql-server/maximum-capacity-specifications-for-sql-server?view=sql-server-ver16


Thanks.
