System that store data that is related to each other are known as database system. Example of database system : mysql, sql+, oracle etc.

A data record is a collection of various fields of data (like name, organisation, sex, age etc), whereas a database is a collection of records tables. (And views, indexes, stored procedures, and other stuff;)
DBMS means Data Base Management System, it is not a programming language.
Base class should no knowledge about derived classes. The "private" modifier on a data member means private to the class which defined it. Base class cannot directly reference/access the private data member of the derived class, and the derived classes cannot access the private data member defined in the base class. Either way the accessing the private data member should be done via properties or getters
#include<iostream> class base { int m_data; public: base(const int data):m_data(data){} base(const base& cpy):m_data(cpy.m_data){} base& operator=(const int rhs){m_data=rhs;return(*this);} base& operator=(const base& rhs){m_data=rhs.m_data;return(*this);} virtual ~base(){} }; class derived { public: derived(const int data):base(data){} derived(const derived& cpy):base(cpy){} derived& operator=(const int rhs){return(base::operator=(rhs));} derived& operator=(const derived& rhs){return(base::operator=(rhs));} virtual ~derived(){} }; int main() { derived d=42; }
data base means a collection of data,which may be inter related. data base management system is a collection of programs for managing the data base.

dbms is data base management system .It is combination of the data base & the the softwares to access the data from the database. eg:Poracle 91,dbase; for more reply to rexrer234@gmail.com
DBS has more security and data integrity.It reduce data redundancy and updating errors which can occur in FBS.Contains of concurrent data access.But also it's expensive to use and they are also complex.Damage to DB affects virtually all application programs.

The full form of DBMS is Database Management System.
The following are the strengths of Database system : 1) data is secured 2) data sharing is easy 3) data can be easily accessed
