hi..plzz read this..!!!

[Ravinder Reddy <pa...@students.iiit.net>]

 	hello all,
 		I am Ravinder Reddy studying B.tech 3rd year in 
IIIT,Hyderabad- India.As my B.Tech project I am planning to implement 
'speculative locking protocol' to Derby.For this I need some help from 
developers like you in  understanding  the architecture of derby and
achieving the project goal.plzz suggest me where can I start to understand 
the code and how can I get maximum benefit.
 		I know this is very complex/large work to do.We are a 
group of 2 people and we have (nearly) 9 months time and we are very much 
interested in database Systems and Java.
 		Considering all the factors plzz guide us to do the 
project effectively.

Q)   what is this 'speculative locking protocol'?.
      ------------------------------------------
Ans)
 	2-phase locking protocol is widely used in database system to 
achieve concurrency control of transaction management.This speculative 
locking protocol is newly proposed locking protocol that outperforms
over 2-phase locking. we want to show this by implementing for an
opensource Database System.So we have chosen Derby.

Q)  why we have chosen Derby?.
     -----------------------
Ans)
 	It is prototype DatabaseSystem.
 	It is in developing stage.
 	we are java geeks.
 	and many more......!!!!!

 		Hoping for a Positive responce..!!
 		Thank U in advance n sorry for spamming..!!


Regards

Welcome to the community, the wiki contains information for getting 
started in Derby development.

http://wiki.apache.org/db-derby/DerbyDev

There are links that lead you to write ups of various sub-systems, 
presentations that cover the internals, etc. The code itself is a good 
source of information, the original plan when the project started was to 
keep as much information in javadoc comments as possible. Here's the 
link to the complete javadoc for the engine.

http://db.apache.org/derby/javadoc/engine/

which itself is a link from this page of papers.

Hope this helps,
Dan.
