Dear Gaurav ,

 

Congratulations! Your proposal “General Feedback Mechanism” as submitted to “OpenMRS” has been accepted for Google Summer of Code 2011. Over the next few days, we will add you to the private Google Summer of Code Student Discussion List. Over the next few weeks, we will send instructions to this list regarding turn in proof of enrollment, tax forms, etc.

Now that you’ve been accepted, please take the opportunity to speak with your mentors about plans for the Community Bonding Period: what documentation should you be reading, what version control system will you need to set up, etc., before start of coding begins on May 23rd.

NoSQL and SQL

 

NoSQL and SQL Databases – Presentation Transcript

  1. Seminar and Progress ReportA comparison between SQL (Conventional) & NOSQL (WebScale) Databases using various scenarios Gaurav Paliwal 0071641507 B.Tech (Information Technology) 8th Semester
  2. What is NoSQLThis does NOT mean “No SQL”
  3. What is NoSQLThis does mean “Not ONLY SQL”
  4. Why is Not only SQLGoogle once ran off of 40,000 MySQL installations
  5. Why is Not only SQLFacebook was at one point spending $1M per month for specialized database hardware to serve their pictures.
  6. Why is Not only SQLThese unviable solutions led to a re-evaluation of existing database technologies and led to the Not-Only-SQL (NoSQL) movement.
  7. The rise of Not only SQL – 1 Googles Way
  8. The rise of Not only SQL – 11. Google invented for BigTable database.
  9. The rise of Not only SQL – 11. Google invented for BigTable database.2. BigTable maps two arbitrary string values (row key and column key)and timestamp (hence three dimensional mapping) into associatedarbitrary byte array.
  10. The rise of Not only SQL – 11. Google invented for BigTable database.2. BigTable maps two arbitrary string values (row key and column key)and timestamp (hence three dimensional mapping) into associatedarbitrary byte array.3. It is not a relational database and can be better defined as a sparse,distributed multi-dimensional sorted map.
  11. The rise of Not only SQL – 11. Google invented for BigTable database.2. BigTable maps two arbitrary string values (row key and column key)and timestamp (hence three dimensional mapping) into associatedarbitrary byte array.3. It is not a relational database and can be better defined as a sparse,distributed multi-dimensional sorted map.4. BigTable is designed to scale into the petabyte range across “hundredsor thousands of machines, and to make it easy to add more machines tothe system and automatically start taking advantage of those resourceswithout any reconfiguration”.
  12. The rise of Not only SQL – 2 Facebooks Way
  13. The rise of Not only SQL – 21. It is a NoSQL solution that was initially developed by Facebook andpowers their Inbox Search feature.
  14. The rise of Not only SQL – 21. It is a NoSQL solution that was initially developed by Facebook andpowers their Inbox Search feature.2. Jeff Hammerbacher, who led the Facebook Data team at the time, hasdescribed Cassandra as a BigTable data model running on an AmazonDynamo-like infrastructure.

Jeff Hammerbacher, who led the Facebook Data team at the time, hasdescribed Cassandra as a BigTable data model running on an AmazonDynamo-like infrastructure.3. Cassandra is an open source distributed database managementsystem.

Cassandra is an open source distributed database managementsystem.4. It is an Apache Software Foundation top-level project designed tohandle very large amounts of data spread out across many commodityservers while providing a highly available service with no single point offailure.
  17. The rise of Not only SQL – OthersHadoop / HBaseHypertableAmazon SimpleDBMongoDBTerrastoreCouchDBMemcacheDBAnd Many others {{The list is Endless}}.
  18. Benefits of NoSQL Databases 1. Elastic scaling
  19. Benefits of NoSQL Databases 2. Big data
  20. Benefits of NoSQL Databases 3. Goodbye DBAs
  21. Benefits of NoSQL Databases 4. Economics
  22. Benefits of NoSQL Databases 5. Flexible data models
  23. NoSQL comparison with SQL 1. ACID
  24. NoSQL comparison with SQL 2. CAP
  25. NoSQL comparison with SQL 3. Maturity
  26. NoSQL comparison with SQL 4. Support
  27. NoSQL comparison with SQL5. Analytics and business intelligence
  28. NoSQL comparison with SQL 6. Administration
  29. NoSQL comparison with SQL 7. Expertise
  30. NoSQL comparison with SQL Practical “Head On”
  31. NoSQL comparison with SQL Questions

FF4 release party #Manav_Rachna

Today on 15 April 2011, I went to the Firefox4 release party in Manav Rachna International University . Prashant was the main person behind this wonderful firefox4 release party event. Me and Narendra reached the college around 11 am.The crowd was electrifying as well as very enthusiastic. First Prashant has given an talk about the firefox4 and new features of firefox4. After that their was a web quiz and Mozilla goodies was given to those who have answered the question. Then it was my talk on FOSS for Academic Institutions which can be found here : http://blog.gauravpaliwal.com/foss-for-college-infrastructure .After their there was cake cutting ceremony and snacks party.Then Narendra discussed various aspects of FOSS in details and student clarified their doubts.
