A database is a structured set of data held in a computer, most often a server. Databases use a database management system (DBMS) that interacts with users, similar to a lookup table. Modern databases are designed to allow for creation, querying, updating, and administration of the data it holds.
Use case:
Add the ability to search for an element in an array and retrieve back the array index.
As per the PostgreSQL documentation:
array_position ( anycompatiblearray, anycompatible [, integer ] ) → integer
Returns the subscript of the first occurrence of the second argument in the array, or NULL if it's not present
运行示例代码，如果把user对应的age和uid属性调换一下时，即使绑定了对应的tag，但是仍然按照数据库中顺序进行赋值，数据库的第一列uid对应的了user类的第一个属性age
