1. PREFACE

This report has been prepared to serve the purpose of documentation for the work I have carried out during my industrial training at Power Grid Corporate Centre Gurgaon .Through this report I would like to share the step by step procedure I followed to learn the building blocks for developing general pupose forms using OpenOffice. The focus of the trainining was realizing the power of XML .It all began from writing simple XML instance and its definition in the form of DTD, XML schema for validation rules, designing Xforms and its binding with XML schema with a purpose of receiving valid input data, generating XML and transferring its data to a database in Microsoft Access. I have tried to cover all above mentioned purposes with the help of simple examples. I hope this report will be beneficial to its readers. With Regards
