Web Service is a programmable Web-based application for developing distributed, interoperable applications and a Web serviceThe characteristics of WebService are as follows:1. Use XML (Standard Universal Markup Language) as the format for data interaction.2. Cross-platform, because the use of XML so long as the local application can connect to the network parsing XML can achieve data exchange, such as Android, IOS, WindowsPhone, etc. can achieve the Web service data interaction.3. Based on the H

the data to be accessed, the connection string also contains identification of why users can access those data. When performing database operations, user identification is the most important factor in determining data access rights. 1.1 Saving the connection string Currently, hard-coded connection strings have the best performance because they are compiled directly into the code of your application. However, hard-coded strings affect the flexibility of the program, and once the connection str
