MyBatis know how (10) application database

Application databases are often the smallest, simplest, and most easy-to-use database. This kind of database is often used by US developers who don't mind using or even very happy to use. The application database is typically in the same project as our application, both designed and implemented. It is for this reason that the design of the application database often has very large degrees of freedom, and it is most likely to match our particular application perfectly. The external impact of the application database is minimal because it usually has only one or two external interfaces. The first interface connects to our application, and the second interface may be a simple report framework or report tool. A high level of presentation of an application database and its relationship to other systems.

The relationship between application databases and other systems the application database is sometimes small to be deployed directly on the same server as the application. Similarly, the requirement for hardware resources to use the application database is also more free.

With small application databases, it is often easier to persuade companies to use cheaper open source RDBMS solutions, such as MySQL or PostgreSQL, without having to spend a lot of money buying Oracle or SQL Server. Some applications are very
It is possible to use an embedded application database that runs in the same virtual environment as the application, so that even a standalone SQL file can be used without the need.

MyBatis as a persistence framework, it supports the application database well. Because MyBatis is very simple, a development team can create a new application very quickly. For a simple database, you can even generate SQL from the database schema by using the management tool that comes with the RDBMS. Similarly, there are tools available that automatically generate all MyBatis SQL mapping files.
