Essential tools for developing web applications

This bachelor thesis is devoted to problems of creating web applications using XML files for data storing. The main mission of thesis is to demonstrate XML language usage in these applications and to introduce a reader with another important languages for development of these applications. This thesis is trying to offer a complex view of this problem. Because success of application largely relies on the fact how easily the applacation can be found by potential users of the web, the thesis describes how can be web sites indexed by search engines. There are two main parts of this bachelor thesis: teoretical and practical. The first chapter describes HTML language with accent on his features that can be used for cooperation with web applications. The second chapter is devoted to XML markup language.

The fourth chapter describes indexing of web pages by search engines and the following fifth chapter describes advanced searching with search engine Google, that can be used for detection if search engine optimization was successfull and if web page is findable. The sixth chapter dedicated to practical part of this thesis. This part describes developed web application programmed in PHP language.
