+## Create table in Oracle database
+
+Tables are the basic unit of data storage in an Oracle Database. Data is stored in rows and columns. A CREATE TABLE statement creates a table. Tables contain columns and constraints, rules to which data must conform. Table-level constraints specify a column or columns. Columns have a data type and can specify column constraints (column-level constraints).
+
+```
+<copy>
+CREATE TABLE table_name (
+    column1_name data_type column_constraint,
+    column2_name data_type column_constraint,
+    ...
+    constraint table_constraint;
+);
+</copy>
+```
+
+### Example
+
+For example, you define a table with a table name, such as employees, and a set of columns. You give each column a column name, such as employee\_id, last\_name, and job\_id; a datatype, such as VARCHAR2, DATE, or NUMBER; and a width. The width can be predetermined by the datatype, as in DATE. If columns are of the NUMBER datatype, define precision and scale instead of width. A row is a collection of column information corresponding to a single record.column information corresponding to a single record.
+
+You can specify rules for each column of a table. These rules are called integrity constraints. One example is a NOT NULL integrity constraint. This constraint forces the column to contain a value in every row.
+
+```
+create table DEPARTMENTS (  
+    deptno        number,  
+    name          varchar2(50) not null,  
+    location      varchar2(50),  
+    constraint pk_departments primary key (deptno)  
+);
+```
+
+Tables can declarative specify relationships between tables, typically referred to as referential integrity. To see how this works we can create a "child" table of the DEPARTMENTS table by including a foreign key in the EMPLOYEES table that references the DEPARTMENTS table.
+
+```
+create table EMPLOYEES (  
+    empno             number,  
+    name              varchar2(50) not null,  
+    job               varchar2(50),  
+    manager           number,  
+    hiredate          date,  
+    salary            number(7,2),  
+    commission        number(7,2),  
+    deptno           number,  
+    constraint pk_employees primary key (empno),  
+    constraint fk_employees_deptno foreign key (deptno) 
+        references DEPARTMENTS (deptno)  
+);
+```
+
+Foreign keys must reference primary keys, so to create a "child" table the "parent" table must have a primary key for the foreign key to reference.
