Super SQL Server Systems: Turbocharge Database Performance with C++ External Procedures
暫譯: 超級 SQL Server 系統：使用 C++ 外部程序提升資料庫效能

Description

This unique book focuses on hypercharging SQL Server database performance with external procedures.

SQL Server runs databases for financial, bank, biotech, Ecommerce, data warehousing, scientific applications, etc. which often require huge data processing with complex formulas or algorithms.

Most of this work is done with TSQL stored procedures and .NET procedures (in SQL Server 2005), however neither one of them can achieve the performance and flexibility of external procedures which are natively compiled code. External procedures are analogous to stored procedures but with the power of C++ for CPU intensive algorithms, hardware/low level access, use of external libraries, etc.

Database administrators/developers can create more efficient code and avoid expensive, slow and unreliable third party tools. There is also the extra bonus of having the source compiled, to protect the intellectual property.

This book is intended for C++ programmers who want to learn about database programming and use their C++ skills seamlessly, and database administrators and/or programmers who need more performance, functionality and versatility than they can achieve with TSQL, .NET procedures or ADO.
