to create all the characteristics of all classes, when the type of specific products continue to increase, the way to create a change in the mode of the factory needs to be constantly changing, increase the corresponding judgment, increase the corresponding class of the creation of logic, resulting in factory class code more and more large, not conducive to the maintenance of the later. In addition, the simple factory pattern uses static methods to create objects, so that the static method of c

to the corresponding subsystem. It is actually only a delegate class with no actual business logic. The high-level module uses the interfaces provided by this role to access sub-interfaces. Subsystem (subsystem role): either one or more subsystems. Each system is a collection of classes. The sub-system does not know the existence of the facade role. In terms of this, the facade role is actually a client. Common Code for facade mode: Subsystem role: /* Subsystem */ Public Class Su

set, while COMPUTE by returns multiple result sets, and multiple result assemblies increase the complexity of the application code.(2) ROLLUP can be used in server cursors, while COMPUTE by is not possible.(3) Sometimes, the query optimizer generates more efficient execution plans for ROLLUP than is generated for COMPUTE by.

Small series has already introduced a lot of Excel features and properties, today to continue to share is how to use Excel to make a drop-down list, the method is more than one, is not very curious about it? Now to share the 3 ways in which Excel makes a drop-down list. Excel makes a drop-down list with a map Making a Drop-down list in Excel can be made by using the data validation, the form control, and the combo box in the VBA Control Toolbox. Let's use a concrete example to illu

record can only be connected to one record of another table, or one-to-many, and a table record is connected to multiple records from another table. The definition of "key" and "index" in MySQL is the same, so the foreign key and the primary key are also one of the indexes. The difference is that MySQL automatically indexes the primary keys for all tables, but the foreign key fields must be explicitly indexed by the user. This is the same as some of the more heavily feudal families, foreign chi

The Drop-down list is widely used in Excel. Making a Drop-down list in Excel can be made from data validation, by using a combo box in the form control and in the VBA Control Toolbox. Let's use a concrete example to illustrate (download the example file in XLS format at the end of the article). If we have a payroll every month, each employee's salary varies according to the number of days of attendance per month. We need to make a "person
