What is Microsoft SQL server and why do I need to install it?

All I want to install is visual web developer (but I've had this issue with other things like visual C# to), so when I choose to install just that from microsoft web platform, it wants to开发者_高级运维 download that, under 3mb, and SQL server (dependency it says,) 100mb. I've seen lots of computers with SQL server installed, does it come with all windows distributions? Do many other applications use it to work? Should I just install it if part of visual studio wants me to? When it asks me to make an administrator account and password for it, should I just type in whatever to get it to install as I won't be using it directly?


What is it?

It is a database system.

does it come with all windows distributions?

No.

Do many other applications use it to work?

Yes.

Should I just install it if part of visual studio wants me to?

Yes. It will hook everything up for you to a copy of SQL Server Express, so no further configuration will be required to make it work.

When it asks me to make an administrator account and password for it, should I just type in whatever to get it to install as I won't be using it directly?

Yes. Remember the user name and password for later use, but you will probably be using Windows Authentication to access SQL Server on your own machine, so you won't need this user name and password on a regular basis.


The reason it is installed along with Visual Studio is because SQL Server is a database system for storing data, and many developers these days are writing applications that work with databases, so the developer often needs a SQL Server installed so that he has a database system to develop and test against. So in a nutshell, if you were writing such an application, you would already know what it is, and would know that you need it. Which is why OrbMan said "If you don't know what it is, you don't need it."

If you get in the mood to learn something new though, I would highly recommend reading about SQL and SQL Server. It is used alot in the real world.
