Final answer:
Without knowing what 'OCB/CDI' refers to, it is impossible to provide the exact frequency of its publication or confirm if it has electronic updates.
Step-by-step explanation:
The question appears to pertain to a specific periodical or publication schedule, which is not clearly identified as the 'OCB/CDI'. Assuming that this is a reference to a financial or business report or index (although not a standard acronym that is widely recognized), such publications can vary widely in their publication frequency. Without exact information on what 'OCB/CDI' refers to, it is not possible to provide a definitive answer to how frequently it gets published or whether it has electronic updates. Typically, business reports or indexes could be published on any of the mentioned schedules, depending on the organization and its reporting practices.
