Consider following while converting ER-Diagrams to Tables:. 1. Minimize the number of tables. 2. There must be one Primary Key for each table. 3. Each cell (column) of a row in a table must have only. one value. #Database.

Relational Schema = Name of the Relation (Table) along with its Attributes (Columns) + Integrity Constraints. #database.

CREATE TABLE Product (.price DECIMAL(10,2) CHECK (price > 0),.discount INTEGER CHECK (discount_percent >= 0 AND discount_percent <= 100),.category VARCHAR(50) CHECK (category IN ('Electronics', 'Clothing', 'Books', 'Home')).);.

6. Check Constraint.- Allows custom rules to be defined for a column or. combination of columns. - Example: Salary must be greater than 0. CHECK (salary > 0).

5. NOT NULL Constraint.- Ensures that a column cannot have NULL values. - Common for mandatory fields. name VARCHAR(100) NOT NULL.

CREATE TABLE User_Account (.user_id INTEGER PRIMARY KEY,.username VARCHAR(50) UNIQUE, -- No two users can have same username.email VARCHAR(100) UNIQUE, -- No two users can have same email.phone VARCHAR(15).);.

4. Unique Constraint.- Ensures that all values in a column (or combination. of columns) are unique across rows. - Allows NULLs unless explicitly stated otherwise.

3. Referential Integrity.- Maintains consistency between two related tables. using foreign keys. - Ensures that the value in the foreign key column. exists in the referenced table. FOREIGN KEY (department_id) REFERENCES department(dept_id).

2. Entity Integrity.- Ensures that each table has a primary key and that. the primary key values are unique and not NULL. - Purpose: Uniquely identify each record in the table. PRIMARY KEY (student_id).

CREATE TABLE Employee (. emp_id INTEGER,. name VARCHAR(50) NOT NULL,. age INTEGER CHECK (age >= 18 AND age <= 65),. salary DECIMAL(10,2) CHECK (salary > 0),. email VARCHAR(100) CHECK (email LIKE '%@%.%'),. hire_date DATE CHECK (hire_date <= CURRENT_DATE).);.

1. Domain Constraint.- Ensures that all values in a column are of the same. data type and within a valid range. - Example: A column "age" must only contain integers. between 0 and 150.

Integrity constraints are rules that ensure the accuracy, consistency, and validity of data within a database. These constraints are enforced at the schema level and prevent the entry of invalid data. #Database #IntegrityConstraints.
