DML Operations dont work on alfresco database

[alihammad]

I cant perform DML Operation on Alfresco database like Insert and Delete from Java. I suppose the Schema Updates are not allowed. But how to configure the datasource or whatever to enable DML operations to work successfully?

Thanks

Alfresco requires exclusive access to its schema.    To insert or delete you should use one of the Alfresco Public APIs and not go to the DB directly.
