C # NPOCO lightweight ORM framework (Getting Started ), Currently, this framework cannot be used to search Chinese documents. Only the English wiki is available. Take an excerpt from translation learning. Most of them are machine flip, and some places have been changed, Because bloggers are also low-level, and the red ones are blind to understanding. There may be errors. You can point them out if you find them. Wiki address: http://github.com/schotime/NPoco/wiki First query: 1 public class Use

First, define an interface named idatabase. In this interface, define the method name, parameters, and return values of database operations. In this case, I define the following methods: Public interface idatabase { Bool connect (string connectstring ); Bool open (); Bool command (string SQL ); Void close (); } Important Note: "The interface should be cautious throughout its life, and its definition should

registered to the tree.}}Five, adapter modeEncapsulates a variety of distinct function interfaces into a unified API.PHP database operation has mysql,mysqli,pdo three kinds, you can use the adapter mode unified into the same, so that different database operations, unified into the same API. A similar scenario also has the cache adapter,Different cache functions, such as MEMCACHE,REDIS,FILE,APC, can be unified into the same.First define an interface (there are several methods, and the correspond

mode to unify the interface. Similarly, the cache scenario is that it is more convenient to change the cache policy (memcache, redis, apc. Advantages: The adapter adapts to the target through the adapter to achieve the goal of being transparent to the customer. Sample code: // Adaptation target. the specified interface will be adapted to the object to implement interface IDatabase {public function connect ($ host, $ username, $ password, $ database

1. Description 1. Adapter Mode: 可以将截然不同的函数接口封装成统一的API2. Practical application example, PHP database operation has MySQL, mysqli, Pdo3 species, can be unified into the same adapter mode. A similar scenario is a cache adapter that unifies different cache functions, such as MEMCACHE,REDIS,FILE,APC, into a consistent3. The following example can help you deal with various database link functions, MySQL mysqli, PDO random selection, operation is abstracted into a unified interface client does

to the target through the adapter to achieve the goal of being transparent to the customer. Sample Code: // Adaptation target. The specified interface will be adapted to the object to implement interface IDatabase {public function connect ($ host, $ username, $ password, $ database ); public function query ($ SQL);} // adapter class Mysql implements IDatabase {protected $ connect; public function connect (

the caching strategy (Memcache, Redis, APC). Advantage: The adapter is used by the adaptor to complete the adaptation target to achieve the purpose of transparent to the customer. Example code: Adaptation target, the specified interface will be implemented interface idatabase{public function Connect ($host, $username, $password, $database); Public Function query ($sql);} Adapter class Mysql implements idatabase
