Migration of Databases – An XML Approach
XML Database Migration is a project of migrating the existing databases into XML format. Conversion of databases to XML file format, the databases like Ms-Access, Oracle and MS-SQL, MySQL connects in the network or the oracle in the personal computer can be connected for the generation of XML code. Let us consider, user runs a firm with three companies with different database’s respectively. User planned to mingle the entire database’s of the firm in to a single database. The user wants to migrate the entire database in to a single database. Migration of a database to another database is a huge process and a complex one. In such case our project can be used as we are converting the entire

In web, database is widely used at present. The database occupies some part of memory in the server and amount should be paid to maintain the database. The amount will depend upon the database size, and also Access and Oracle database are platform dependent. XML is platform independent. While using database, lot of problems will be arise like data corruption, huge memory spaces, and unnecessary expenses for database security.
Now a days most of the websites stores data in backend storage device. The data are stored in Oracle database or some other backend devices. These databases occupy some part of memory in the server. The site owner should be paid some amount of money to maintain that database. The amount should be vary depending upon the database size and also have a lot of problem to maintain the database. This is unnecessary expenses and waste of memory spaces. To retrieve the data from the database is very slow when we are browsing the site. These are the difficult arising to retrieve the database.
Drawbacks
There are lots of problems in the existing system. They are,
Data corruption will occur.
Requires huge memory space.
Unnecessary expenses for database security.

The flexibility of XML has made it the standard for the formatting and sharing of data via the web. XML data is easily transferable across machines and applications and is not constrained by the operating system of the host machine. This ease of translation enables XML to be transformed into non-XML formats for use with databases and their associated applications.
Abstract--- This research is on SAP S/4HANA business suite which help enterprises run simple and delivers massive simplifications like customer adoption, data model, user experience, decision making. This new suite is built on advanced in-memory platform, SAP HANA. SAP S/4HANA can help your business lead in the digital economy.
Database consolidation is an important aspect of any server consolidation effort and the reining in of escalating server sprawl. Just as virtualization of the datacenter brings cost and management benefits to IT administration, database consolidation contributes many of the same benefits plus a few of its own:
Although the database system yields considerable advantages over previous data management approaches, database systems do carry certain disadvantages. Such as:
Database Management System plays a vital role in most of the real world applications that require storing and retrieving data. Database Management Systems are the most reliable means to organize data. DBMS organizes data into collections from which data can be searched or updated to. There are many different forms and types of DBMS products available in the market each having their own pros and cons. The main DBMS products that are available in today’s market are Oracle 11g, Microsoft SQL Server 2012, IBM DB2 and MySQL 5.5.
| XML is a flexible data description language that allows Web-based communication between different hardware and software environments.
Any database can be rum on the amazon platform which is built to be flexible as possible, we are using MYSQL, IBMDB2, Oracle, postgre SQL, and some databases for complete storage to run these databases production. However, there is a considerable measure of work in building and keeping up these databases services must be valid to a team. In late 2009 we build relational database services which aims to streamline in the creation of relational databases can support MYSQL and ORACLE we can spend up any databases and consistencies with nice additional features. Social database administration can have versatile capacity were we can easily increase the amount of data to be stored in data storage, Rapid provisioning, High availability options more than NOSQL, Scalable compute to increase the amount of memory or cpu put your databases as your Query required. There are couple of common patterns to setting up high performance databases, we can Increase throughput by scaling up the physical resources available in the cloud we can add read replicas and Elastic ache. Increase availability by multi availability deployments, Reduce
•Prepare database design documents using the data definition, data manipulation, and data control language components of the SQL language.
New tables and fields to support new application functionality or enhancements are requested by developers and added to the oracle databases. Duplicate fields are created for the same data element in the database as a result of developers working on similar subject areas. A new field is created because there is no central repository documenting existing data elements. The same data element exists in duplicate fields and updated by multiple applications. Materialized views created from one database to another include logic to modify data due to an application requirement. Developers must review the code in the views due to the lack of documentation in a central repository. In some cases, a new materialized view is created for the same data set. A major challenge in loading the new data warehouse is identifying the correct tables and fields to use as the source of the loads. The extract transformation and load code (ETL) to load the data into the new analytics database cannot be developed until all tables and fields impacting timelines.
In the world of computer science large groups of data collected are referred to as databases. When there is a multitude of these databases, a way to manage all of the information is
XML is popular as a format for documents as well as databases. Many applications use XML files to store their configuration, and rely on it for remote procedure calling services like XML-RPC and SQL to format the messages that they exchange using XML. XML’s structure allows it to be tested to ensure that it 's both well-formed and valid in a standardized, programmatic like fashion in order to take a lot of the reading and modifying of the data file off of the application developer when he or she is writing a program. XML might need to be integrated with a relational database. The structured operability of XML makes it a good choice for use with a data interchange format. As an example let 's imagine that a company routinely receives inventory information from a supplier. That information might be stored in something like an Oracle database on a server in the supplier 's system but may need to be imported into a database such as an Access database when the company receives it. XML would make a good intermediate format for the data because of it 's easy to write programs that import and export all the data and because, by using XML the data can be used in future applications that would require it as well. Another example might be a service like Yahoo! Finance. Yahoo finance is a web site that provides financial information, including stock quotes, stock exchange rates, international market data, and much more. Consumers can receive financial data in XML format from Yahoo!

Database management system software (DBMS) is the software that can operate on the front and back end of an organization’s database. As do the database requirements of an organization differ, so do the types of DBMS software. The type of DBMS software required can often be narrowed down to the organization’s size and industry (Mohamed 2016). Currently, the top three DBMSs are Oracle, MySQL, and Microsoft SQL Server (“Microsoft SQL Server vs. MySQL vs. Oracle Comparison” 2016). Each having its own forte; however, in this assessment, only MySQL and Microsoft SQL Server (MS SQL Server) will by compared and contrasted to one another in the aspects of an organization’s needs, the hardware requirements, and the database
Data Conversion for databases, word processors, spreadsheets, and many other standard and custom-made software packages as per requirement.
This dialect shows such a great amount about database programming and C.i have created this undertaking with the assistance of Faculty parts of my Institute AIIT, and as being what is indicated I am greatly thankful to every one of them. I am obliged to my venture guide Dr Dolly Sharma .
