SQL Server 2005 Database Development Overview

This article discusses some of the new features of SQL Server 2005 that will help you create a new type of database application.

The way database development is changing as Microsoft SQL Server, the release of Beta 2, is released. As a database developer, you can now better focus on functionality, access to native-formatted data (such as XML), and the use of powerful database servers to create more complex systems. Database development is becoming more integrated than ever before, and all the tools you need are within reach.

. NET Framework Integration

With the release of Microsoft SQLServer2005 BETA2, database programmers can now take full advantage of Microsoft. NETFramework class libraries and modern programming languages to develop database applications. By integrating the CLR, you can use the. NETFramework language in Visual Basic.NET and C # Object-oriented architecture, structured error handling, arrays, namespaces, and classes to write stored procedures, functions, and triggers. Moreover,. The thousands of classes and methods provided by NETFramework also extend the functionality of the server, making it easier for you to use on the server side. Many of the tasks we used to implement with T-SQL are now easier to implement with managed code. At the same time, the system also added two database object types: Aggregation and user-defined types. You can now better use the knowledge and skills you have mastered to write in-process code. In short, SQL Server2005 Beta2 makes it easier for your database server to perform the appropriate calculations and operations in the background.

The integration of SQL Server and CLR provides the following benefits:

1. Enhanced programming Model:. NETFRAMEWORK-compliant programming languages are more powerful in many ways than T-SQL, and provide the architecture and functionality that SQL developers did not have before.

2. Enhanced security: Managed code running in a CLR environment is controlled by the database engine, which makes. NETFramework database objects can be more secure and have better security than extended stored procedures in previous versions of SQL Server.

3. User-defined types and aggregations: With the host CLR, these two new database objects extend the storage and querying capabilities of SQL Server.

4. Common Development Environment: database development is integrated into the Microsoft Visual Studio2005 development environment. Used to develop the middle tier and the customer layer. The tools for NETFramework components and services can also be used to develop and debug database objects and scripts.

5. Performance and Scalability: Because managed code is compiled into native code for priority execution, performance can be significantly improved in some situations.

6. With CLR integration, you can write code with more complex logic and code that works more well with computational tasks in languages such as Visual Basic.NET and C #. Also, Visual Basic.NET and C # also provide object-oriented features such as encapsulation, inheritance, and polymorphism. You can now make it easier to organize code and classes, namespaces, which means that you're more likely to organize and maintain a lot of code generated at work. This logic and physical ability to organize code into assemblies and namespaces is useful, and will enable you to better discover and correlate different blocks of code in a large database implementation project.

Managed code is more efficient at processing operations and managing complex execution logic than T-SQL, and provides additional support for functions such as string processing, regular expressions, and so on. In addition, because you can now take advantage of the capabilities of the. NET Framework class Library, you can easily access thousands of built-in classes and routines (routines) from stored procedures, triggers, and user-defined functions. Managed stored procedures, functions, triggers, aggregations make it easier to implement functions such as string processing, mathematical functions, date operations, free access to the system, advanced encryption algorithms, file access, image processing, and XML data manipulation.

One of the main benefits of managed code is type safety. Before managed code executes, the CLR performs some checks to ensure that the code being executed is safe through a process called "validation." For example, the code is checked to make sure that the unread memory address is not read.
