This document describes a final year project to develop an SQL converter tool. The tool will convert SQL database files to XML and JSON file formats. The objectives are to identify suitable semi-structured data formats for converted structured SQL data and develop a tool that allows users to upload SQL files, select an output format, and download the converted XML or JSON files. The project uses Java and follows an iterative development methodology. The prototype developed allows users to perform basic SQL to XML/JSON conversions through a web interface.

2. INTRODUCTION
Background
 SQL is a language for querying data that is represented as a table but it does not tell how those
tables are store. In this project, a converting tools is developed to share data information between
applications as XML and JSON format.
 In converting a structured data to semi-structured data, there are choices for select semi-
structured data format from structured data. In this scenario, structured data (MySQL) stores data
in database or actually is a database, for passed data from server to client or passed to webpage for
javascript to consume and present to the user, the data need to be reconstructed to semi-structured
to store data as text file for save the data. In addition, data that need to be share between
application or system have to organized in a complex manner that makes it sophisticated to access
and analysis. However, it may have information associated in it for allowing elements contained to
be addressed. Thus, developing a converter tools may help user to organize application in web
service from different sources to communicate with each other without time-consuming custom
coding, because all communication is in XML or JSON

3. WEB SERVICE
Web service commonly provides an object-oriented web-based interface to a database server, utilized
by another web server, or by a mobile app, that provides a user interface to the end user. Web
services describes a standardized way of integrating Web-based applications using
the XML, SOAP, WSDL and UDDI open standards over an Internet protocol backbone.
• XML is used to tag the data.
• SOAP is used to transfer the data.
• WSDL is used for describing the services available.
• UDDI is used for listing what services are available.
Web services allow different applications from different sources to communicate with each other
without time-consuming custom coding, and because all communication is in XML, Web services are
not tied to any one operating system or programming language.

4. WEB SERVICE ARCHITECTURE

5. ADVANTAGES OF WEB SERVICE
• Exposing Business Functionality on the network - A web service is a unit of managed code that provides some sort of
functionality to client applications or end users. This functionality can be invoked over the HTTP protocol which means
that it can also be invoked over the internet. Nowadays all applications are on the internet which makes the purpose of
Web services more useful. That means the web service can be anywhere on the internet and provide the necessary
functionality as required.
• Interoperability amongst applications - Web services allow various applications to talk to each other and share data
and services among themselves. All types of applications can talk to each other. So instead of writing specific code which
can only be understood by specific applications, you can now write generic code that can be understood by all
applications
• A Standardized Protocol which everybody understands - Web services use standardized industry protocol for the
communication. All the four layers (Service Transport, XML Messaging, Service Description, and Service Discovery
layers) uses well-defined protocols in the web services protocol stack.
• Reduction in cost of communication - Web services use SOAP over HTTP protocol, so you can use your existing low-
cost internet for implementing web services.

6. XML AND JSON
XML and JSON are the two most common formats for data interchange in the Web today. XML was created
by the W3C in 1996, and JSON was publicly specified by Douglas Crockford in 2002. Although their
purposes are not identical, they are frequently used to accomplish the same task, which is data
interchange.
Purposes
 XML’s purpose is document markup. It accomplishes this purpose by giving semantic meaning to text
through its tree-like structure and ability to represent mixed content. Data structures can be represented
in XML, but that is not its purpose.
 JSON’s purpose is structured data interchange. It serves this purpose by directly representing objects,
arrays, numbers, strings, and booleans. Its purpose is distinctly not document markup. JSON does not
have a natural way to represent mixed content.

7. ADVANTAGES XML & JSON
XML
• Namespaces allow for sharing of standard
structures
• Better representation for inheritance
• Standard ways of expressing the structure of
the document: XML schema, DTD, etc
• Parsing standards: DOM, SAX, StAX
• Standards for querying: XQuery and XPath
• Standards for transforming a document: XSLT
JSON
• Smaller message size
• More structural information in the document
• Can easily distinguish between the number 1
and the string "1" as numbers, strings (and
Booleans) are represented differently in
JSON.
• Can easily distinguish between single items
and collections of size one (using JSON
arrays).
• Easier to represent a null value
• Easily consumed by JavaScript

8. METHODOLOGY

9. ITERATIVE AND INCREMENTAL MODEL
• Iterative model were developed to overcome the weaknesses of the waterfall model.
It starts with an initial planning and ends with deployment with the cyclic
interactions in between. The basic idea behind this method is to develop a system
through repeated cycles (iterative) and in smaller portions at a time (incremental),
allowing software developers to take advantage of what was learned during the
development of earlier parts or versions of the system. It can consist of mini
waterfalls or mini V-Shaped model.

10. ADVANTAGES AND DISADVANTAGES
OF
ITERATIVE MODEL
Advantages
• Produces business value early in the development
lifecycle.
• Better use of scarce resources through proper
increment definition.
• Can accommodate some change requests between
increments.
• More focused on customer value than the linear
approaches.
• We can detect project issues and changes earlier.
Disadvantages
• Requires heavy documentation.
• Follows a defined set of processes.
• Defines increments based on function and feature
dependencies.
• Requires more customer involvement than the
linear approaches.
• Partitioning the functions and features might be
problematic.
• Integration between the iterations can be an
issue if it is not considered during the
development and project planning.

11. OBJECTIVES
The main objectives of this project is to develop a tools that can convert
structured data(SQL) to semi-structured data(XML/JSON) using Java. In
order to succeed the above project, the objectives of this project are as follows :
• To identify semi-structured data file format that needed from structured
data.
• For help simplify the reconstructing semi-structured data from structured
data.
• To develop a tools that can convert SQL files to XML or JSON file format.

12. SCOPE
This project focus on developing a converting tools for user use based on their needs,
this system include;
• Target user :
• User
• Access system
• Upload file to convert
• Load from URL
• Write SQL database
• Convert SQL file to XML or JSON format
• Download converted file
• Save File
