  • This illustrates that like most industry
    buzzwords, Big is a cynical spin on what should
    more often be called awkward. A billion rows of
    normalized data in a well-designed schema might
    be large, but it's hard to see a big pay packet
    coming from running an aggregate function like
    Average on it. To be a lucrative skill there has
    to be some pain that you can overcome for your
    patient employer.

  • Save point are used to divide a transaction
    into smaller parts. It enables rolling back part
    of a transaction. Maximum of five save points are
    allowed. Whenever we encounter error we can
    rollback from the point where we set our save
    point. This is useful for multistage transaction
    and conditional transaction where commit and
    rollback depend on certain condition. This is
    another commonly asked Oracle Interview Question
    and since save points are also available in other
    database e.g. SQL Server, some time Interviewer

    for the design, implementation, support and
    maintenance of computerized databases in today's
    organizations. The role also includes
    architecting, building and scaling databases for
    future data growth and capacity. They are also
    responsible for security, performance and
    availability of data to users and customers. .
  • All the above tasks are performed with the help
    of a Database Management System (DBMS) and the
    leading and most widely used DBMS across the
    world today are the Oracle Database, Microsoft
    SQL Server, My SQL database etc. Out of the three
    DBMS technologies, Oracle Database is the most
    popular and widely used database in the world
    today.

  • Each database requires at least one database
    administrator (DBA) to administer it. Because
    an Oracle database system can be large and can
    have many users, often this is not a one person
    job. In such cases, there is a group of DBAs who
    share responsibility.
