Use the valuable Entity Framework Core 2.0 tool in ASP.NET and the .NET Framework to eliminate the tedium around accessing databases and the data they contain. Entity Framework Core 2.0 greatly simplifies access to relational databases such as SQL Server that are commonly deployed in corporate settings. By eliminating tedious data access code that developers are otherwise forced to use, Entity Framework Core 2.0 enables you to work directly with the data in a database through domain-specific objects and methods. Beginning Entity Framework Core 2.0 is a carefully designed tutorial. Throughout the book you will encounter examples that you can use in your day-to-day coding, and you will build a solid foundation on which to create database-backed applications. If you are looking for a way to get started without getting buried under details you are only going to forget, then this is the book for you. The author aims to leave you comfortably able to connect to, access, modify, and delete data from a relational database. The book provides a clear, straightforward approach and includes code that you can look back at months later and understand.

pb开发的应用程序自动升级程序 ------------------------------------------------------------- --软件名称：软件自动升级系统 --适用范围：pb8 + mssql server 2000 --开发日期：2003-09-26 --版权所有：Susue 未经许可不得仿制，反编译 --系统原理：将系统文件打包，存入数据库，升级时再还原为磁盘文件 -------------------------------------------------------------- --使用简单说明 --1--数据库连接，首先配置 dbc.ini 文件的 [Update] 小节（即连接参数） --2--打包文件，运行 ftd.exe 将系统用到或升级用到的文件打包进数据库，一次只能上传 1 个文件。 --3--升级程序，直接运行 dtf.exe 即可，或在程序中调用，方法如下： run('dtf.exe') halt close 备注：(系统必须的文件) mssql 直连需3个文件 dbnetlib.dll dbnmpntw.dll ntwdblib.dll pb8 运行库需4个文件 libjcc.dll （可选） pbvm80.dll （必须） pbdwe80.dll （可选） pbmss80.dll （必须） -------------------------------------------------------------- --软件名称：软件自动升级系统 --适用范围：pb8 + mssql server 2000 --开发日期：2003-09-26 --版权所有：Susue 未经许可不得仿制，反编译 --系统原理：将系统文件打包，存入数据库，升级时再还原为磁盘文件 -------------------------------------------------------------- --使用简单说明 --1--数据库连接，首先配置 dbc.ini 文件的 [Update] 小节（即连接参数） --2--打包文件，运行 ftd.exe 将系统用到或升级用到的文件打包进数据库，一次只能上传 1 个文件。 --3--升级程序，直接运行 dtf.exe 即可，或在程序中调用，方法如下： run('dtf.exe') halt close 备注：(系统必须的文件) mssql 直连需3个文件 dbnetlib.dll dbnmpntw.dll ntwdblib.dll pb8 运行库需4个文件 libjcc.dll （可选） pbvm80.dll （必须） pbdwe80.dll （可选） pbmss80.dll （必须）
