XML and database

Abstract: This paper briefly discusses the relationship between XML and databases, and lists some software that can use databases to process XML documents. Although I am not going to introduce these software in detail here, I hope it can describe the main part of the XML document for processing data using databases.

1.0 Introduction


This paper briefly discusses the relationship between XML and the database, and lists some software that can use the database to process XML documents. Although I am not going to introduce these software in detail here, I hope it can describe the main part of the XML document for processing data using databases. This is a bit biased towards relational databases because of my experience.



2.0 is XML a database?


Before we begin to discuss XML and databases, we need to answer a lot of questions: "Is XML a database? "Strictly speaking, if" XML "is an XML document, the answer is" no ". Although the XML document contains data, if there is no other software to process the data, it has no difference in the meaning of the database and other text files.
