Abstract - XML is a popular and highly used markup

very crucial point to work. Different languages such as Document Type Definition (DTD), eXtensible Stylesheet Language Transformations (XSLT). XML documents can also be restructured using Document Type Definition (DTD). For creating a mediate architecture of XML schemas, eXtensible Stylesheet Language Transformations (XSLT) can be used. XML (eXtensible Marked Language) provides solution for data integration of information. As there are large, complex and different types of queries, a fixed mapping is not possible to work. An XML document contains a root element following the nested elements. Elements can be either attributes or sub-elements.
1. INTRODUCTION
2. RELATED WORK
Nowadays, internet is growing rapidly and there is a wide use of database system, many numbers of independent databases has been planned and created in distributed environment. All these miscellaneous or different databases are different in structures. To eliminate the conflict between heterogeneous data, data exchange takes place in heterogeneous databases. However, in certain cases there is necessity of information transmission in many application systems. Therefore, in heterogeneous databases system, data exchange between them becomes an important point of discussion. Big amount of semi-structured and structured data is stored with the help of XML technique. XML technique is also used for exchanging data from source to destination. Whenever large amount of information is stored, data transformation and data manipulation is necessary. The database that are maintained here are mostly heterogeneous and distributed. XML is designed to represent data in the form of tags (elements); it allows information to be expressed in such ways that match better for business. It brings powerful properties such as flexibility, heterogeneity, and extensibility to information modelling. That is the reason, XML has become a standard data format widely used for data transmission over the Internet as well as in these organizations and a common language. This leads to an increasing need for exchanging and integrating the heterogonous XML data sources and schemas between different application systems. Therefore, data exchange between different and heterogeneous databases becomes
The purpose of data exchange is to realize data share among systems. The aim of XML tag is to spot every XML element unambiguously and to show constructive relationship. The constructive symbol called XML tag allotted for every node in XML document is extra knowledge to the subject. Post Order Numbering (PON) mentioned follows post order traversal requires a lot of space for tag that is a significant disadvantage. A famous coding method for trees known as Dewey coding is mentioned. M-IBSL (Modified Improved Binary String Labeling) is explained within that partition XML DOM nodes into sensitive and public nodes[1]. The content of public nodes is additionally sent at the same time when the encrypted sensitive nodes is being send, which is an extra information needed to reconstruct the XML document at the buyer. Therefore, leakage of extra information is not prevented. XML-based information exchange has gained researchers attention with development of internet technologies.
language which is used because of its simplicity, generality, and usability. As a result, it is widely used in modern computing. Integrating multiple data sources has become important. This paper explore heterogeneous data sharing to acquire transparent operation and continuous heterogeneous data integration, and also focus on the basic properties of XML data exchange based on available heterogeneous database integration systems.

Work to be done by researchers here was to study the conversion of XML document to relative information and transformation methods between relational models and XML. In [2], researchers studied the related theories to XML and relative models and proposed a data-exchange model in ecommerce system. Data exchange between different ERP systems is needed to be designed and implement in an interactive way. They proposed a tool to map elements of one schema to another. They studied linguistic conflicts in heterogeneous database systems and divided them in ISO 9001:2008 Certified Journal
