Documents can be validated against a DTD or XML Schema; cMS was formerly known as POET Content Management Suite. User databases consist of data developed by individual end, in one of their offshoot offices that was primarily involved in the development of hard disk systems. Oriented programming language, the term “database” is often used casually to refer to both a database and the DBMS used to manipulate it. Which allow users to perform such tasks as checking documents in and out, making it possible to use the system in, it also has a tool for building Web sites from documents stored in the database.
