SQL Server edition	Description
Developer (64-bit and 32-bit)	SQL Server 2012 Developer edition lets developers build any kind of application on top of SQL Server. It includes all the functionality of Enterprise edition, but is licensed for use as a development and test system, not as a production server. SQL Server Developer is an ideal choice for people who build and test applications.
Express (64-bit and 32-bit) editions	SQL Server 2012 Express edition is the entry-level, free database and is ideal for learning and building desktop and small server data-driven applications. It is the best choice for independent software vendors, developers, and hobbyists building client applications. If you need more advanced database features, SQL Server Express can be seamlessly upgraded to other higher end versions of SQL Server. New in SQL Server 2012 is SQL Server Express LocalDB, a lightweight version of Express that has all of its programmability features, yet runs in user mode and has a fast, zero-configuration installation and a short list of prerequisites.

Using SQL Server with an Internet Server

On an Internet server, such as a server that is running Internet Information Services (IIS), you will typically install the SQL Server client tools. Client tools include the client connectivity components used by an application connecting to an instance of SQL Server.

[!UWAGA]

Although you can install an instance of SQL Server on a computer that is running IIS, this is typically done only for small Web sites that have a single server computer. Most Web sites have their middle-tier IIS systems on one server or a cluster of servers, and their databases on a separate server or federation of servers.

Using SQL Server with Client/Server Applications

You can install just the SQL Server client components on a computer that is running client/server applications that connect directly to an instance of SQL Server. A client components installation is also a good option if you administer an instance of SQL Server on a database server, or if you plan to develop SQL Server applications.

The client tools option installs the following SQL Server features: backward compatibility components, SQL Server data tools, connectivity components, management tools, software development kit, and SQL Server Books Online components.
