Oracle database 12c includes a number of changes that will allow FDA to reach a wider audience.

Flashback uppgifter Archive provides the ability to automatically track and store all transactional changes to a record for the duration of its lifetime.

Hur mycket matematik använder man på jobbet?

Väldigt lite matematik. Däremot skadar det inte att lära sig hur man räknar ut procentenheter, medelvärdet/median samt korrelation

Är det ett jobb för introverta eller sociala personer?

Tänk på att dom flesta arbetsgivare kräver att du kan SQL och Bigquery.
