How to quickly and efficiently access sdks-channel SDK access (that is, implementing the abstraction layer interface) and SDK Channels Question: Many people who develop games probably take over the Channel SDK, UC, dangle, 91, Xiaomi, 360 ...... according to statistics, there are currently no more than 100 channels in the domestic market, and there are also some small channels without sdks. The SDK access

databases are unified, but more advanced features are not excluded. ? PHP scripts provide optional abstract/compatibility. We have proposed the concept of this PHP Data Object (PDO) because we want to use Zend Engine 2 (the core of PHP 5) advanced object-oriented features to achieve better performance of this API Beijing cleaning. The concept of the data abstraction layer in PHP is not new at all. queryi

lot of methods, using this class, to operate all the following databases, as long as PHP loaded the database driver, it can be, if not installed the driver of this database, it is not operational, As long as the driver is installed, PDO can use a statement to operate all the database, want to change which, you can change the name.PDO: Data Access Abstraction LayerIt actually, is to merge the middle piece into the same, it uses a class, the class enca

Ogre implements API independence through an abstraction layer. Now there are two implementations: rendersystem_direct3d9 and rendersystem_gl. The following describes the API abstraction layer and its implementation by examining rendersystem_direct3d9. The API abstraction

This article mainly introduces the method of using PDO in the database abstraction layer in php. Taking PDO for database connection, insertion, query, and other operations as an example, it analyzes the related skills of PDO in database operations, for more information, see This article mainly introduces the method of using PDO in the database abstraction

This article designs the PHP database abstraction layer for ACCESS. This class library focuses on efficiency and is easy to use. Especially for virtual machine users, the ACCESS database is free of charge and does not need to rent the MSSQL database space, saving a certain amount of money. Php database APIs have different functions for different databases. Some people have been trying to use php object-orie

Database Abstraction Layer:Provides a solution for ease of operation when data migration and project operations are multi-database.When migrating from one database system to another, there is almost no need to change too much program code, such as migrating MS SQL Server to MySQL.Code planning must be prescriptive, using the same data as possible for object instantiation, and using the same database abstraction
