Abstract: “Basic requirements to process historic data are finding, collecting, structuring and retrieving. Key challenges facing by historians during transformation are heterogeneous data format, data exchange, cross platform, multiple languages etc. Conversion between source and recipient database is also a difficulty. During the transformation, data sharing and data security are the key concerns faced by historians. Data exchange, compatibility, extendibility and reuse of data becomes progressively important while collecting and processing data. Here combination of Java with XML is checked to resolve above concerns. How the features of Java and XML can be supportive for data sharing, data extension and cross platform issues are being discussed here. These paper insights into the historians everyday practices to manage constraints and concerns in the areas of data access, collection, sharing and security. This paper reveals how the usability of XML and Java can reduce the challenges and enhance”
