The reason for combining these two databases is that ms SQL Server is the third generation product of Sybase SQL Server launched by Sybase in 1987, also known as the University edition Ingres, so they are essentially the same.
The new version of SQL Server is SQL Server 7, which has a single process with more clues. And SQL Server has only one server process, and all customers are connected to this process. However, the process is subdivided into multiple concurrent clues. They share the data buffer zone and CPU time, and can capture the data access requests sent by various user processes in a timely manner. Then, processing these requests based on certain scheduling algorithms is much more efficient than directly scheduling these requests by the operating system.
Microsoft provides a database engine for applications ranging from a mobile laptop running Microsoft Windows 95/98 operating system to a megabyte-symmetric multi-processor cluster running Windows NT Server Operating System Enterprise Edition. All these systems ensure the security and reliability required by the Business System for key tasks.
The transaction processing capacity of SQL Server is large, and the response speed is fast. It can maintain this high performance for hundreds or more users.
SQL Server first implements data integrity control at the core layer, including declaring integrity during table creation and defining application-related integrity using the trigger mechanism. Supports distributed queries and updates.
Sybase was founded in 1984 and is a rising star. He launched a database that supports the enterprise-wide "customer/server architecture. Sybase regards the "customer/Server database architecture" as an important goal for product development. They learned from the development experience of INGRES to meet the requirements of online transaction processing applications, and launched Sybase SQL Server in 1987, known as the third-generation INGRES product of the university edition.
SYBASE system 11.5 is its latest product that supports various internal database application requirements, such as data warehouses, online transaction processing, decision support systems, and small platform applications.
Database Server
Sybase is a powerful relational database management system (RDBMS) with high performance and reliability for online transaction processing ). The features of Sybase databases include multiple databases, multiple devices, multiple users, and multiple clues, which greatly enrich and enhance database functions. Because the Sybase Database System is such a complex and multi-functional system, it becomes very important to manage the Sybase Database System. The quality of management is closely related to the performance of the database system.
The server side and new product of sybase system 11.5 are adaptive servers. It integrates with the original Server series, such as SQL Server, SQL Anywhere, Sybase IQ, and Sybase MPP. It has the ability to process multiple data sources, including legacy non-relational data and distributed transactions, provides optimized data storage and access methods, and provides a single programming model.
