History of SQL in RDMS
As we know, pre-relational databases did not have a set of commands to work with
data. Each database either had its own exclusive language or used programs composed as a
part of COBOL, C, so on to control records. Likewise, the databases were for all intents and
purposes inflexible and did not permit any internal structure changes without bringing them
disconnected and revising huge amounts of code. That worked pretty much viable until the
end of the 1960s when most PC applications were constructed entirely in light of batch
handling (Stephens, 2002) .
Structured Query Language
SQL is the set of statements with which all programs and users get to information in
an Oracle database. Application projects and Oracle devices regularly permit clients access to
the database without utilizing SQL specifically, yet these applications thus should utilize
SQL when executing the client's demand.
