簡介:
Enterprise Edition (32-bit and 64-bit)
Enterprise Edition scales to the performance levels required to support the largest enterprise online transaction processing (OLTP), highly complex data analysis, data warehousing systems, and Web sites. Enterprise Edition s comprehensive business intelligence and analytics capabilities and its high-availability features such as failover clustering and database mirroring allow it to handle the most critical enterprise workloads. Enterprise Edition is the most comprehensive edition of SQL Server and is ideal for the largest organizations and the most complex requirements. Note: To evaluate 64-bit edition features, please download the September version of the CTP, not the June version.
Standard Edition (32-bit and 64-bit)
Standard Edition is the data management and analysis platform for small and medium-sized organizations. It includes the essential functionality needed for e-commerce, data warehousing, and line-of-business solutions. Standard Edition s integrated business intelligence and high-availability features provide organizations with the essential capabilities needed to support their operations. Standard Edition is ideal for the small- to medium-sized organization that needs a complete data management and analysis platform.
Workgroup Edition
Workgroup Edition is the data management solution for small organizations that need a database with no limits on size or number of users. Workgroup Edition can serve as a front-end Web server or for departmental or branch office operations. It includes the core database features of the SQL Server product line and is easily upgradeable to Standard or Enterprise Edition. Workgroup Edition is an ideal entry-level database that is reliable, robust, and easy to manage.
Developer Edition (32-bit and 64-bit)
Developer Edition allows developers to build any type of application on top of SQL Server. It includes all of the functionality of Enterprise Edition, but is licensed for use as a development and test system, not as a production server. Developer Edition is an ideal choice for independent software vendors, consultants, system integrators, solution providers, and corporate developers who build and test applications. Developer Edition can be upgraded to SQL Server Enterprise Edition for production use.
Express Edition
Express Edition is a free, easy-to-use, and simple-to-manage database. Integrated with Microsoft Visual Studio 2005, Express Edition makes it easy to develop data-driven applications that are rich in capability, more secure in storage, and fast to deploy. Express Edition is free and can be redistributed (subject to agreement), and functions as the client database as well as a basic server database. Express Edition is an ideal choice for low-end independent software vendors, low-end server users, nonprofessional developers building Web applications, and hobbyists building client applications.
