paradigm. This causes Luce to store two passwords .. This is obviously incorrect. Solution: Bcnf definition: Each definite factor is a key. This paradigm is especially used to deal with the primary key portion of a non-key field. In the preceding quarterly_bonus table, a non-key field SSN determines the employee_id, which is part of the key. In fact, SSN and employee_id are mutually determined. Therefo

Members of the Human Resources Department can modifyEmployeedataTable, which contains sensitive employee salary information. If an employee's social insurance number (SSN), annual salary, or bank account is changed, an audit record is generated and insertedAuditemployeedataAudit table. By using the columns_updated () function, you can quic

Microsoft SQL Server. When several tables must store the same data type, and to ensure that these columns have the same data type, length, and can be empty, you can use user-defined data types. For example, you can define a data type called postal_code, which is based on the char data type.When creating a user-defined data type, three data types must be provided: the data type name, the system data type based on, and the data type can be empty. (1) create a user-defined data type You can use th

stored procedure sp_addtype can be used to create user-defined data types. The syntax format is as follows:Sp_addtype {type}, [, system_data_bype] [, 'null _ type']Type is the name of the user-defined data type. System_data_type is the data type provided by the system, such as decimal, Int, and char. Null_type indicates how the data type handles null values. It must be enclosed by single quotation marks, such as 'null', 'not null', or 'nonull '.Example:Use custExec sp_addtype

clearly described in the article. I will do my best to do this here, but now you are ready to browse the following design patterns (Principles)DRY-Don't repeat yourself Our first object-oriented design principle is: DRY. From the name, we can see that DRY (don't repeat yourself) refers to abstracting code into reusable code blocks instead of repeating code. If you have more than two identical code blocks, consider abstracting them into a separate method. Or if you have used hard-coded values mu

Thinking about java objects, java objectsImmutable objects and Classes An object created by an immutable class is an immutable object. To make a class immutable, it must meet the following requirements: All data domains are private. No modifier Method If there is no accessor method, it returns a reference pointing to a variable data domain. See the following code: Public class Main {public static void main (String args []) {Student student = new Student (11222333, "John"); java. util. date

If no parameter is included during use, netstat displays active TCP connections. The common format of this command is: Netstat [-a] [-e] [-n] [-o] [-p Protocol] [-r] [-s] [Interval] Output Information After netstat is executed, the output result is Active Internet connections (w/o servers)Proto Recv
