SQL servers have a CREATE command to create a new schema in the database. The following creates a schema for customers, quantities, and price of transactions: CREATE TABLE customer ( id INT AUTO_INCREMENT PRIMARY KEY, postalCode VARCHAR() default NULL, ) CREATE TABLE product ( id INT AUTO_...
The principle of QBE is that it is merely an abstraction between the user and the real query that the database system will receive. In the background, the user’s query is transformed into a database manipulation language form such as SQL, and it is this SQL statement that will be ...
Inheritance is a process in which one object acquires all the properties and behaviors of its parent object automatically. In such way, you can reuse, extend or modify the attributes and behaviors which are defined in other class. The class which inherits the members of another class is call...
Snow Information Abstraction Based on Remote Sensing Data: Taking the North of Xinjiang for Example 遥感数据积雪信息新疆北疆卫星数据这篇论文用 MODIS 数据在北 Xinjiang 盆为雪信息抽象建议一条适用的途径.线性光谱混合分析(LSMA ) 被用来在一个象素以内计算积雪部分(SF ) ,它被用来与 NDSI 建立一个回归...
