Two parts to this question:
Are there any existing file formats or software libraries that can be used for scoring, archiving and/or analysing cricket games?
Are there any examples of database schemas suitable for recording all of the details of a cricket game?
Cricksheet offers ball-by-ball match data for the recent year in yaml format. The specification of their yaml format can be found here - http://cricsheet.org/format/ .
But, I really don't understand this 3 day thing everyone keeps talking about. Test matches last 5 days, One-day matches last, well, one day and T20 matches last close to 4 hours.
Only exhibition first-class matches or practice matches are played for 3 days, and I am wondering why anyone is talking about it here if that is what they are indeed talking about.
As you will know cricket is a complex game and commentator needs lots of stats to rehash over 3 days or more.
So short of someone sharing proprietary info, you probably better off designing an XML schema(may be) to store the data.
Good luck

I need to design some data structures for something that's roughly a cross between a database and a file system. In fact there's a large overlap in the design of file systems and databases. I've done some work on both, not very in-depth, but still, I have some idea about the topics. However I need more information and I am wondering if there's a good overview of design concepts out there. Things like overviews of algorithms, data structures and the like. The advantages of different types of trees or hash tables for key lookup. Perhaps some information about data ordering an alignment. In short, the experiences of other people in implementing filesystems and databases that would help the next person avoid the same mistakes.
Gray wrote a book titled "Transaction Processing: Concepts and Techniques" - http://www.amazon.com/Transaction-Processing-Concepts-Techniques-Management/dp/1558601902 - which covers a great deal of what you would need to build your own database.
One starting point for file systems would be http://www.amazon.com/The-Design-UNIX-Operating-System/dp/0132017997 - but I suspect you would have to chase down individual papers or Linux source code to keep up with the variety of different file systems created since then.

I have knowledge of sql-server but i am trying to learn Sybase, I need some basic help in that, please ignore if my questions are too silly.
Where can i get this database (sybase) for practice, I went on the official site, but it asks me to fill lot of details, is it changeable ?
2.Can you please suggest a basic book for this?
How different is it form SQL-Server?
For a free product it's the least you can do to fill in a form
No. I learnt from online help.
SQL Server was actually built from Sybase many years ago back at version 6.0 (maybe 25 years ago) but has now of course branched off. You'll find a lot of the functions are the same.

I am new to database schema design and I want to learn more about how a well-designed database scheme is implemented in the real world?
Is there any places to find those schemes? Or is there any book focused on explanation over examples.
DatabaseAnswers.org (unfortunately now defunct) but well-preserved in the Wayback Machine is a great source of example database schemas.
I can also recommend Beginning Database Design, published by Apress. I own this book and can confirm that it is of high quality. The book looks at a number of real world scenarios and explains the impact a certain design decision could have on the way the database works and the quality of the data and its output.
Finally I would advise building some small databases (E.G. contact management, Task list etc). Start by specifying some basic requirements and create some tables and queries. You WILL make some mistakes which is the best way of learning.
Here is a nice library of schemas to browse through.

I am relatively new in the field of Data Mining. I am currently doing Some Data preprocessing algorithms such as PCA and min max Normalization. Our professor said we could download the data sets available over the web. But at initial level I want a simple data set with relatively small number of attributes for my algorithm, and would then switch to various complex data sets.
Can anyone provide a link for simple data sets which you must have used in your data mining algorithms? e.g. something pertaining to marks of students, age, height etc or employee data of a company. Any assistance would be greatly appreciated.

More and many more links here: Some Datasets Available on the Web
I used stackoverflow's data for my data mining class.
I am not sure this is going to help or not, but I gathered some websites that provided useful Data when I was working with recommender systems.

I'm looking for a good reference card / cheat sheet that compares T-SQL and PL/SQL data manipulation language commands side-by-side.
I've previously searched SO but there isn't any older thread covering this particular subject so I thought it'd be a good idea to start one, given that such reference is almost mandatory if you happen to work in an environment where both technologies coexist.
Thanks much in advance!
This is pretty good. In ye olde paper and inke, SQL in a nutshell is also useful.
I found this PDF which goes into detail about syntax examples between the two:
Note: The PDF is from 2003 so it may not be update to date with new features from SQL Server 2005 or 2008 (such as the RowNum() function).
