Description

technical field

[0001] The invention relates to the field of computer technology, in particular to a method and device for storing and reading multi-valued data and a system for accessing it. Background technique

[0002] In the existing technology, one key (key) corresponds to one value (value) data operation. For example, a function method generally only has one return value. When multiple values ​​need to be returned, it is difficult to realize that one key corresponds to multiple values. Data processing efficiency is low.

[0003] For example, as a cross-platform development method, Java technology is widely used in PC platforms, embedded platforms, mobile terminals and the Internet. With its excellent versatility, efficiency, platform portability and security, Java technology has significant advantages and broad prospects in the global cloud computing and mobile Internet industry environment. As an open technology, Java is compatible with various platform systems and ...
