Tags: style color using OS IO data ar problemDefinition: A view is a table that is exported from one or several base tables, and is a virtual table, unlike a base table.Role:1. Simplify the operation without making multi-table queries. 2. When different types of users share the same database, very flexible, (users with differentWay of looking at the same data.3. The view provides a degree of logical independence to the refactoring database.The logical independence of data refers to the addition

. Hierarchical database and mesh database generally can support the physical independence of the data, but the logical independence can not be fully supported. in the related database, the reconfiguration of the database is often unavoidable. The most common way to refactor a database is to divide a base table "vertically" into multiple base tables. For example: The student relationship student (sno,sname,ssex,sage,sdept), is divided into SX (sno,sna
