MySQL storage engine sorting and MySQL storage engine sorting01.MyISAMDefault storage engine before MySQL 5.0. MyISAM does not support transactions or foreign keys. Its advantage is that the access speed is fast, you can use this engine to create tables for applications that do not require transaction integrity or that use SELECT or INSERT statements. Each MyISAM
ObjectiveI've been talking about Androidui, but it's not over yet, and I'll add it later. Today, I'll talk about other things about data persistence. For an application, it is unavoidable to be able to store the data, and the Android program is no exception. In Android, there are several ways to implement data persistence. The following will be described separately.In Android, data persistence can be achieved in several ways:
