frameworks such as Hibernate typically uses a custom query language i.e. the Hibernate Query Language HQL or Enterprise JavaBeans Query Language EJBQL. MYBATIS Design Features MyBatis comes with the following can to facilitate hyper-fast development. Portability − MyBatis can be implemented for nearly any language or platform such as Java, Ruby, and C# for Microsoft .NET. Independent Interfaces − MyBatis provides uses JAVA programming language while developing database oriented application. Before proceeding further, make sure that you understand the basics of procedural and object-oriented programming − control

distributed governance, applicable in a variety of situa‐ tions such as Java isomorphism, heterogeneous language and cloud native. Apache ShardingSphere aiming at reasonably making full use of the computation HintManager, but the condition is only effective within the current thread. In addition to the programming method, Apache ShardingSphere also plans to cite Hint through special notation in SQL, so that decorator merger. Parse Engine Compared to other programming languages, SQL is relatively simple, but it is still a complete set of programming language, so there is no essential difference between parsing
