EXTENSIBLE MARKUP LANGUAGE

XML (Extensible Markup Language) is a markup language much like HTML. It was designed to carry data, not to display data. It is classified as an extensible language because it allows its users to define their own elements. XML language has no predefined tags. Its primary purpose is to facilitate the sharing of structured data across different information systems, particularly via the Internet. In other words, we can say that XML is a software and hardware independent tool for carrying information.

Difference between XML and HTML

XML is not a replacement for HTML.XML and HTML were designed with different goals:

• XML was designed to transport and store data, with focus on what data is.HTML was designed to display data, with focus on how data looks.
• HTML is about displaying information, while XML is about carrying information.

WHAT IS DBMS?

DBMS stands for "Database Management System." In short, a DBMS is a database program. Technically speaking, it is a software system that uses a standard method of cataloging, retrieving, and running queries on data. The DBMS manages incoming data, organizes it, and provides ways for the data to be modified or extracted by users or other programs.

Some DBMS examples include MySQL, PostgreSQL, Microsoft Access, SQL Server, FileMaker, Oracle, RDBMS, dBASE, Clipper, and FoxPro. Since there are so many database management systems available, it is important for there to be a way for them to communicate with each other. For this reason, most database software comes with an Open Database Connectivity (ODBC) driver that allows the database to integrate with other databases
