Native MS Access Barcode generator is a VBA module that can be easily embedded in a Microsoft Access database to create a barcode image on a report. Once installed into a database, you do not need to install any other fonts or components when creating barcodes; it is a complete barcode generator that is used with the database, even when it is published.Specific f

correct. Therefore, as a best practice, it is not recommended to enable pattern generation in a production environment by manually maintaining the table mechanism. To disable mode generation, configure the configuration file Persistence.xml as follows:The generation strategy for the Generator table primary key is the generator table, which is uncommon and is typically used for legacy databases using JPA.
