In the case of the chemistry database, the situation is more complex. Compound data cannot be queried or updated using standard SQL. The read and write operations are encapsulated in vendor-specific Oracle data cartridges. Therefore, the Data Persistence Layer has another responsibility— hide vendor specifics with a standard interface so that the Business Layer does not care about vendor variations. 

The control unit and software. While the assay is being run, the control unit (figure 18.6(6)) displays instructions on an LCD display for the user and directs the flow of data in the instrument. The control unit prompts the user to follow menu-driven instructions to set up the chemistry, run the assay, and collect and store data. A keypad allows the user to respond to the instructions at each step of the assay. As a qualification step, each cartridge undergoes a specification check during the test.
