1.Introduction
Big Databases mainly consist of an amazingly high number of tuples i.e rows, or involves an
incredibly substantial physical data file framework storage because of its wide tables with huge
number of columns or some multimedia objects like images videos etc. Nonetheless, the most
widely recognized meaning of large database is a database that involves more than 1TB or that
consist of billion rows. As we know that, organizations develop naturally and through mergers or
we can say acquisitions, that is the main reason for measure of processed information to double.
Information from various internal information sources as well as external information sources are
extricated and changed into the data warehouse center. External information sources can be
because of transactions from various sites or from structured data models like relational, object
oriented, Hierarchical etc. Information from these drives can be extricated, changed, and can be
standardized into a typical information model and merged with the goal that they can be utilized
over the undertaking for better decision making processes.
Data warehouse gives a magnificent way to deal with changing the gigantic measures of
information that exist in the associations into helpful and dependable data for finding solutions to
various queries and to help the efficient decision making process. Associations have gigantic
measures of information yet have discovered it progressively hard to access it and make
utilization of it. This is on the grounds that, it is in numerous diverse arrangements, exists on
various platforms, and lives in a wide range of record and database structures created by various
users. [1] Our research will be based on which database should be selected for better decision
making in given scenario and what type of principles as well as strategies needs to be followed
while implementing database?
