Global SQL table mapping in persistent classes

#Caché

In Persistent class, a data global is created which holds the data similar to the table created . Through terminal we can add more records to this table according to the structure of the table. How are the records reflected back into the table which has been set at global . In other words How are the global mapped to the SQL table?

Within a persistent class you have also a Storage definition describing the structure of the stored data.
In addition access code for SQL projection is generated during the compile process.
Using Inspector in Caché Studio you will find a bunch of SQL specific parameters to control the presentation of your class and properties.
The whole model of describing Objects + SQL tables is known as Unified Data Architecture.
