Type of database in database management

                                                     
There are two types of databases in database management, operational databases
and  analytical databases.
                                                      
 operational databases
 ─────────────────────
► This type of database is primarily used in online transaction processing (OLTP)
  scenarios, that is, in situations where there is a need to collect, modify, and
  maintain data on a daily basis.
► The type of data stored in an operational database is dynamic, meaning that it
  changes constantly and always reflects up-to-the-minute information.
► Organizations such as retail stores, manufacturing companies, hospitals and
  clinics, and publishing houses use operational databases because their data
  is in a constant state of flux.

 analytical databases.
 ─────────────────────
► Analytical databases are primarily used in online analytical processing (OLAP)
  scenarios.
► where there is a need to store and track historical and time-dependent data.
  An analytical database is a valuable asset when there is a need to track trends,
  view statistical data over a long period of time, and make tactical or strategic
  business projections.
► This type of database stores static data, meaning that the data is never (or very
  rarely) modified. The information gleaned from an analytical database reflects a
  point-in-time snapshot of the data.
► Chemical labs, geological companies, and marketing analysis firms are examples of
  organizations that use analytical databases.
►► Analytical databases often use data from operational databases as their main data
   source, so there can be some amount of association between them;
►► operational and analytical databases fulfill very specific types of data processing
   needs and creating their structures requires radically different design methodologies.
