    Study Notes

    • A new database named "ventas" is created to demonstrate creating relationships between tables.
    • Three tables are created: "productos", "facturar", and "detalle".
    • The "productos" table has two fields: "codigo" (short text, primary key) and "nombre_producto" (short text).
    • The "facturar" table has four fields: "fecha" (date/time), "n_factura" (number, primary key), "doc_identidad" (number), and "cliente" (short text).
    • The "detalle" table has five fields: "codigo" (short text), "n_factura" (number), "cantidad" (number), "precio" (currency), and "importe" (calculated field, multiplying "cantidad" and "precio").
    • The relationships between the tables are established, with the "codigo" field in "productos" related to the "codigo" field in "detalle", and the "n_factura" field in "facturar" related to the "n_factura" field in "detalle".
    • Data is entered into the "productos" table, including three records with codes "001", "002", and "003".
    • A form is created using the "facturar" and "detalle" tables, with fields selected from both tables.
    • The form is designed to display data by facturas, with a subform for the detalle records.
    • The form is used to enter new records, with automatic calculations for the "importe" field in the "detalle" table.
