Federated database management system issues in C++

Database Management System or DBMS in short refers to the technology of storing and retrieving usersí data with utmost efficiency along with appropriate security measures.

Federated Database management system is a special type of DBMS in which transparently maps more that one autonomous database into one database which is federated database.

The federated database management system is useful while working with multiple applications that uses federation of databases.

There are some issues with the federated database management system. They are −

• Managing the difference in data models, while working with federated databases multiple applications can have different type of data models and dealing with these data models using is single language is difficult.
• Working with different constraints in data, Databases have multiple constraints on data. Creating a single global schema to work with all constraints is quite difficult.
• Difference in Query languages is a big issue while working with federated databases.
