Explanation / Answer
A procedural language interface is necessary because nonprocedural access and application development tools of database software are sometimes not powerful enough or do not provide the level of control necessary for significant application development.
True ->Correct
Explanation:
I just want you to walk through the basic of Procedural and non-procedural
procedural language-> It is a type of language that consists of steps that will seqentially excecute and return the output.
example -> c/c++/java/python......(list goes...)
Non-procedural language->It is type of lanuage that ne need to define steps explicitly only need to specify what you want to
do. Language like SQL , give the command and it gives u output e,g SELECT in SQL.
No come to question as we cant define steps in non-procedural access so we depent on procedural programming in software
developement. it helps to write the code in more flexible manner and can define what to do. Now a days where DB is more critical
part we using it from procedural programming language.
