+## DBDataFaker
+Generates inserts query for <br />
+- [x] Employee 
+- [ ] Department (to be implemented)
+- [ ] Instructor (to be implemented)
+- [ ] Student (to be implemented)
+- [ ] Course (to be implemented)
+- [ ] and so on ...
+
+## Usage
+**Employee demo** 
+```java
+public class App {
+    public static void main(String[] args) {
+        // Employee demo
+        int N = 10; // number of rows
+        for (int i = 0; i < N; i++) {
+            System.out.println(new ConcreteEmployeeBuilder()
+                    .buildFirstName()
+                    .buildLastName()
+                    .buildAddress()
+                    .build().toString());
+        }
+    }
+}
+```
+This generates 10 rows of employee's insert queries.
+```sql
+insert into employee (first_name,last_name,address) values ("Cara","Cremin","515 Kuvalis Locks, Morriston, PE");
+insert into employee (first_name,last_name,address) values ("Jarrell","Kunde","20356 Carey Flats, South Alanis, QC");
+insert into employee (first_name,last_name,address) values ("Clark","Lowe","86216 Ethyl Village, South Alexzanderstad, NT");
+insert into employee (first_name,last_name,address) values ("Sonya","Beer","531 Bruen Viaduct, Hickleberg, NL");
+insert into employee (first_name,last_name,address) values ("Liam","Hyatt","295 Xzavier Plain, Lake Keegan, QC");
+insert into employee (first_name,last_name,address) values ("Romaine","Wyman","9160 Green Way, North Lenna, QC");
+insert into employee (first_name,last_name,address) values ("Katlynn","Schmeler","611 Pete Curve, Bodemouth, PE");
+insert into employee (first_name,last_name,address) values ("Vivien","Schuppe","15766 Orn Throughway, Lydiafort, ON");
+insert into employee (first_name,last_name,address) values ("Jeromy","Brakus","9058 Shields Ranch, Anthonyfort, PE");
+insert into employee (first_name,last_name,address) values ("Roselyn","Kris","312 Felipa Route, Fritschbury, BC");
