Edition : SQL
Server 2012 Enterprise Edition supports 160 physical processors. It support all
advanced availability features (e.g., table partitioning, data compression,
creating and managing a SQL Server cluster). SQL Server 2012 manages thousands
of connections. It includes both the core database engine and add-on services,
with a range of tools for. It can manage databases as large as 524 petabytes
and address 2 terabytes of memory.
Developer
Edition: The Developer Edition is the same as the

can be easily upgraded to Enterprise without reinstallation. This edition is available to
download by students free of charge as a part of Microsoft's Dream Spark
program.
Standard
Edition: SQL
Server Standard edition includes the core database engine, along with the
stand-alone services. It supports fewer active instances (number of nodes in a
cluster) and does not include some high-availability functions such as hot-add
memory (allowing memory to be added while the server is still running), and
parallel indexes. It is a good choice when advanced
functions (such as data compression, compressed backups, indexed views, etc.)
are not required for the business.

option for small and medium-sized organizations. ItIncludes the core functionality
needed for non-mission-critical e-commerce, data warehousing, and line-of-business
solutions.
