Formally, a "database" refers to a set of related data accessed through the use of a "database management system" (DBMS), which is an integrated set of computer software that allows users to interact with one or more databases and provides access to all of the data contained in the database (although restrictions may exist that limit access to particular data).
An example of a database abstraction layer on the language level would be ODBC that is a platform-independent implementation of a database abstraction layer. The user installs specific driver software , through which ODBC can communicate with a database or set of databases.
Some reasons cloud accounting software is preferred by users is there is no need to worry about maintenance or hardware system upgrades, it can reduce overall costs, and that a user can gain access from multiple locations. One of the primary reasons cloud accounting software is not being used is the threat of the security of the data. [7]
