For those who are new to SQL databases, they are relatively unfamiliar with the differences and choices of SQL Server versions. Although this question is simple, its impact is not small. For those who are new to SQL databases, there are many questions about SQL versions similar to these, but they are too lazy to study them carefully. Although the problem is simple, the impact is not small.
Version difference
SQL Server 2000 has four editions: Enterprise Edition/Standard Edition/Personal Edition/Development Edition
Enterprise Edition and Standard Edition need to be installed on the server operating system, such as Windows NT Server/Windows 2000 Server/Windows 2003 Server, etc.
The personal version needs to be installed on a personal operating system, such as Windows98/Windows 2000 Professional/Windows XP Home/Windows XP Professional, etc.
The development version can be installed on any Microsoft operating system.
SQL Server 2000 Enterprise Edition
Used as a production database server. Supports all features available in SQL Server 2000 and scales to the performance levels required to support the largest Web sites and enterprise online transaction processing (OLTP) and data warehouse systems.
SQL Server 2000 Standard Edition
Use as a database server for small workgroups or departments.
SQL Server 2000 Personal Edition
For use by mobile users who are sometimes disconnected from the network but are running applications that require SQL Server data storage. Personal Edition is also used when running stand-alone applications that require local SQL Server data storage on client computers.
SQL Server 2000 Development Edition
For programmers to develop applications that use SQL Server 2000 as a data store. While the Development Edition supports all features of the Enterprise Edition, enabling developers to write and test applications that use these features, the Development Edition can only be used as a development and test system, not as a production server.
SQL Server 2000 Windows CE Edition
Use Microsoft® SQL Server 2000™ Windows® CE Edition (SQL Server CE) for data storage on Windows CE devices. Data can be replicated using any version of SQL Server 2000 to keep Windows CE data synchronized with the primary database.
SQL Server 2000 Enterprise Evaluation Edition
A fully functional version is available for free download from the Web. For evaluation of SQL Server functionality only; this version will cease to function 120 days after download.
In addition to these versions of SQL Server 2000, the SQL Server 2000 Desktop Engine component allows application developers to distribute copies of the SQL Server 2000 relational database engine with their applications. Because the database engine in the SQL Server 2000 Desktop Engine functions similarly to the database engines in all versions of SQL Server, the size of the Desktop Engine database cannot exceed 2 GB.
Version compatibility
Here is a simple comparison of these versions:
SQL Server includes Enterprise Edition, Standard Edition, Personal Edition, Development Edition, Desktop Engine (MSDE), Evaluation Edition, and CE Edition
1. The evaluation version is for evaluation, and the CE version is for Windows CE, so I won’t go into details.
2. Functionally, the Enterprise Edition and Development Edition are a pair, and the Standard Edition and Personal Edition are a pair. The enterprise version and development version are mainly used for large users. They can support more CPUs and memory, and can support advanced functions such as clustering, log shipping, parallel DBCC, parallel creation of indexes, and index views.
3. From the installation point of view, the Enterprise Edition and the Standard Edition are a pair, and the Personal Edition, Development Edition and Desktop Engine are a group. The Enterprise Edition and the Standard Edition can only be installed on the Server version of Windows (NT, 2000, 2003). The personal version, development version and desktop engine can be installed on more systems (including NT Workstation, 2000 professional, XP, etc. 98 can only install the personal version or desktop engine, but the database of the desktop engine cannot exceed 2G).
4. Use the Enterprise Edition, Standard Edition or Desktop Engine when it is put into operation (the Personal Edition and Development Edition are used for the development of the Standard Edition and Enterprise Edition respectively).
Differences between Standard Edition and Enterprise Edition
1. Whether to support MSCS cluster
2. Whether to support full-text indexing
3. Whether to support distributed partition view
4. Whether log shipping is supported
5. Whether to support CPU utilization of indexed views
The Enterprise Edition provides the highest usability, stability and concurrency, while the Personal Edition and MSDE hard-fill certain codes so that the performance is greatly reduced after more than five concurrent users.
Standard Edition
Database engine features missing failover clustering (up to four nodes), support for failover in SQL Server Enterprise Manager, log shipping, parallel DBCC, parallel CREATE INDEX, enhanced read-ahead and scan, indexed views, federated database servers, support System Area Network (SAN), Graphics Utility with Language Settings, Missing User-Defined OLAP Partitioning for Analysis Services, Partition Wizard, Linked OLAP Cubes, ROLAP Dimension Support, HTTP Internet Support, Compute Units, Writeback to Dimensions, Support Ultra-large dimensions, real-time OLAP, distributed partitioned cubes, SMP only supports a maximum of 4 CPUs under win2000, and a maximum of 8 CPUs under NT (Enterprise Edition)
If you buy 10 licenses, you cannot have 20 users (usually the number of concurrent users is limited, and the number of connections depends on the OS)
Enterprise Edition
Used as a production database server. Supports all features available in SQL SERVER 2000 and scales to the performance levels required to support the largest Web sites and enterprise online transaction processing (OLTP) and data warehouse systems.
