Mobile Device database engine.

This is the Python project , done as a part of python elective course.

Begining stage of the project

---

commands:(for commandline with inmemory database)

• save - to load the data to the database
• query - to query the database
• close - to close the connection with the server

Query format:

---

  <li> SELECT mobiles FROM 'company' WITH 'features' </li>
  <li>conditions: </li>
  	<li><ul>
     <li> Companies can be any company.To search in all the companies give company name as 'all'</li>
     <li> Features must be specified as follows \n \t feature operator value</li>
     <li> WITH clause is mandatory</li>
     <li>To get multiple the info of mobile with two or more features seperate each feature with an 'AND'</li>
     <li> Operators supported : '=', '&lt;', '&gt;'</li>
    <li>features list <ul>
				<li> operatingsystem</li>
				<li>price</li>
				<li> frontcamera</li>
				<li> rearcamera</li>
				<li> model</li>
				<li> thickness</li>
				<li> talktime</li>
				<li> GPS </li>
				<li> type</li>
				</ul></li>
	</ul></li>			
</ul>
<p>To check for the existence give 00mp for camera specifications
Example query:
Say a user wants to get the info of samsung mobiles with windows os and price less than 
	<br>10000Rs and with GPS and with rearcamera
 The query will be
	
	 SELECT mobiles FROM Samsung WITH operatingsystem = windows and cost &lt; 10000
	<br>AND GPS = yes AND rearcamera &gt; 0 
<p> 
	<h4>Later stages of the project</h4>
	<hr>
	<ul>
		
		<li>The inmemory database is organised according to company names : each company directory contains <br>
			the mobile data of that company - A kind of abstration which makes searching very easier.
		</li>
		<li> As a part of this project a sockect client and socket sever which<br> serves multiple clients are implemented</li>
		<li> A simple web server is written in python which seves multiple <br>clients using rest API(JSON is used here).</li>
		<li> The data is crawled from the website gsmarena.com using regex <br> and later regex is substitudes with beatiful soup libray for crawling </li>
		<li> The database used to store the data is mongodb. In the earlier stages of this project <br>
			an in memory databse is used. </li>
		<li>The project is comepletly ported to google app engine cloud and <br>it uses google data store as database management system</li>
