Is the database simple or the network technology simple? Please, great gods
The computer science level three exam included two parts: database system and computer network technology. For database systems, the knowledge points were relatively scattered. It was relatively more complicated to master the knowledge of the SQL language, the principle of the relationship database, and the design of the database. On the other hand, computer network technology mainly involved network protocol, network topography, network security, and other aspects of knowledge. Relatively speaking, the knowledge points were more concentrated and less difficult. Therefore, in terms of learning difficulty, computer network technology might be easier. However, both database systems and computer network technology required sufficient practice and practice to master the relevant knowledge and skills. Therefore, no matter which part was chosen as the test content, one needed to study and prepare carefully.
Simple online bookstore database design
The database design of the online bookstore should include the following components: 1. Item Information Table (Item) -Store the basic information of the item such as title, author, price, description, classification, etc. 2. Order Information Table ( Order) -Store the order information of the customer, including the order number, customer name, order status, order items, etc. 3. Stock-Storage of stock information, including item number, stock quantity, purchase date, supplier, etc. 4. Order Management-used to record all orders created, modified, deleted, and the status of the order (completed, in progress, not processed, etc.). 5. Customer Information Form-used to record the basic information of the customer, such as name, email address, telephone number, etc. 6. The payment information table-used to record all payment methods such as credit card, AliPay, Weixin Pay, etc. 7. The supplier information sheet-used to record the basic information of the supplier, such as company name, address, contact information, etc. The following is a simple online bookstore database design example. The product information table, order information table, and inventory information table already include some basic data fields: ``` --Item Information Form (Product) CREATE TABLE Product ( Product_ID INT PRIMARY KEY Product_Name VARCHAR(50) NOT NULL Product_Price DECIMAL(10 2) NOT NULL Product_Description TEXT NOT NULL Product_category VARCHAR(20) NOT NULL FOREIGN KEY (Product_ID) REFERENCES Product(ID) ); --Order Information Form (Order) CREATE TABLE Order ( Order_ID INT PRIMARY KEY Customer_Name VARCHAR(50) NOT NULL Order_Status VARCHAR(20) NOT NULL Order_Product VARCHAR(50) NOT NULL Order_Time TIMESTAMP NOT NULL FOREIGN KEY (Order_ID) REFERENCES Order(ID) ); --Storage Information Form (Stock) CREATE TABLE Stock ( Stock_ID INT PRIMARY KEY _ Arrival_Date Date NOT Empty <strong></strong><strong></strong> FOREIGN KEY (Stock_ID) REFERENCES Stock(ID) ); --Order Management CREATE TABLE Order Management ( Order_ID INT NOT NULL Order_'s status VarCHAR(20) NOT nil Order_'s method VARCHAR(20) NOT nil FOREIGN KEY (Order_ID) REFERENCES Order(ID) ); --Customer Information Form CREATE TABLE Customer ( Customer_ID INT NOT NULL Customer_Name VARCHAR(50) NOT NULL Customer_Email VARCHAR(100) NOT NULL Customer_Phone VARCHAR(20) NOT NULL FOREIGN KEY (Customer_ID) REFERENCES Customer(ID) ); --payment information form (Payment) CREATE TABLE Payment ( Payment_ID INT NOT NULL Payment_Name VARCHAR(50) NOT NULL Payment_Type VARCHAR(20) NOT NULL Payment_Time TIMESTAMP NOT NULL FOREIGN KEY (Payment_ID) REFERENCES Payment(ID) ); ``` In the above design, each table has a unique ID as the primary key to ensure the uniqueness and integrity of the data. At the same time, in order to support multi-currency transactions, the payment information table also included a payment type field to distinguish different payment methods.

The most trashy body-tempering martial arts, Crouching Bull Fist + Diamond Sutra = transcendent-grade body-tempering martial arts, Vajra Crouching Bull Fist. While the young master of the Li Residence was still fighting for a superior-grade body-forging martial art, Wu Hu was already cultivating a transcendent-grade body-forging martial art.

While others were still sleeping, he was secretly working hard. "Not only is the environment in the Dream Realm good, but the spiritual energy is also abundant. I really want to stay in there for the rest of my life." Unfortunately, it was dawn! The Dream Realm could only be entered after sunset, and they had no choice but to come out when the sun rose. As a result, Yang Feng's cultivation state was divided into two.

It's fine if it doesn't make a sound, but it's amazing.] In Langlang Village, he was hoeing with a farmer and eavesdropping on a private school lecture. "Strength as a bull +1" "Slightly proficient in writing +1" In the sect competition, disciples would compete and observe the selection. "Fire Life Spiritual Root +1" "Brilliant Sword Heart +1" With such help, Han Ye's heart was filled with hope. He developed steadily, worked hard to accumulate attributes, and increased his strength to transform and become stronger silently. That year, the gears of fate began to turn. No one had expected that the cultivation world, which had been peaceful for ten thousand years, would start to fall into chaos!
