What is .mdf and .ldf file in SQL Server

Author: abhays          Posted Date: April 14, 2014    Category: Sql Server     Points: 40

The .mdf and .ndf are the data files of the database, where all of the tables, indexes (other than fulltext catalogs), stored procedures, etc. are stored. The .mdf is the primary data file and the .ndf only exists if a new file group is created.

The ldf is the transaction log. The transaction log is where all transactions are wirtten to. Upon a checkpoint the contents of the transaction log, .ldf is written to the appropriate .mdf and/or .ndf.

Difference between IEnumerable and IComparable

Author: abhays          Posted Date: April 10, 2014    Category: .NET Framework     Points: 40

IComparable is implemented by types that you wish to give them the ability to compare themselves to other instances of the same type, when sorting for example.

IComparer is implemented by a type that you wish to use as a sorting predicate when sorting a collection. This allows you to create several classes that will compare the same two instances in different ways thus creating a different sort order.

Array.Sort will use each element's IComparable implementation to sort the values or it can receive an IComparer to choose the order.

For more information read How to use the IComparable and IComparer interfaces in Visual C#

IEnumerable is an interface that represents the ability to iterate through the collection using an iterator. For example, anything that implements IEnumerable can be iterated through using a for-each loop. Both the Array and List<T> classes implement the interface, and so can be used in a for-each loop.

It isn't a collection in itself, it just represents a behaviour that actual collections may (and usually do) have.

The generic equivalent of IEnumerable (IEnumerable<T>) also serves as the source of many LINQ extension methods also, as LINQ extensions usually require the ability to enumerate over collections, and anything that implements IEnumerable<T> will have that behaviour.

What is difference between build and rebuild

Author: abhays          Posted Date: April 07, 2014    Category: .NET Framework     Points: 40

Build means compile and link only the source files that have changed since the last build, while Rebuild means compile and link all source files regardless of whether they changed or not. Build is the normal thing to do and is faster. Sometimes the versions of project target components can get out of sync and rebuild is necessary to make the build successful. In practice, you never need to Clean.

A build compiles only the files and projects that have changed. This is generally pretty fast. A rebuild rebuilds all projects and files in the solution irrelevant of whether they have changed or not. You normally do a rebuild when many files have changed (especially outside the IDE) and you want to ensure that all the changes are rebuilt. A rebuild can take a while for large projects so normally is only used periodically in the IDE. However for automated builds a rebuild is normally the only type of build done since you always want all the source rebuilt.
