## 📐 ER Diagrams
### Conceptual ERD (Entity-Relationship Diagram)
The conceptual model shows the high-level entities and their relationships without implementation details:
**Key Entities:**
- **Job Seeker** - Central entity with attributes for personal info, career level, and industry
- **Employer** - Company entity with establishment details and contact information
- **Job** - Job posting entity linking employers to job seekers through applications
- **Education** & **Experience** - Supporting entities for job seeker qualifications
---
### Physical ERD (Database Schema)
The physical model shows the actual database implementation with tables, columns, data types, and foreign key constraints:
**Implementation Details:**
- All primary keys use `IDENTITY(1,1)` for auto-increment
- Foreign key constraints ensure referential integrity
- Boolean fields use `BIT` type with appropriate defaults
- Date fields use `DATE` and `SMALLDATETIME` types
- Salary fields use `DECIMAL(10,2)` for precision

## 🔍 SQL Queries & Analytics
This project includes **6 powerful analytical queries** to extract meaningful insights from the recruitment data:
### Query A: Most Popular Job Title
> *What was the most interesting job "title" that had maximum number of applicants?*
```sql
SELECT TOP(1) M.job_title AS [Job Title],
M.NumOfApplies AS [Number Of Applies]
FROM (
SELECT Job_title.job_title, COUNT(*) AS NumOfApplies
FROM Application
JOIN Job_post ON Job_post.ID = Application.id_jobpost
JOIN Job_title ON job_title.ID = Job_post.jobtitle_id
GROUP BY job_title
) AS M
ORDER BY M.NumOfApplies DESC;
```
---
### Query B: Jobs Without Applicants
> *What was the announced job "title" that hadn't any applicants last month?*
```sql
SELECT DISTINCT Job_title.job_title
FROM Job_title
JOIN Job_post ON Job_title.ID <> ALL (
SELECT job_title.ID
FROM Application
JOIN Job_post ON Job_post.ID = Application.id_jobpost
JOIN Job_title ON job_title.ID = Job_post.jobtitle_id
WHERE created_at BETWEEN
DATEADD(day, 1-DAY(EOMONTH(CURRENT_TIMESTAMP,-1)), EOMONTH(CURRENT_TIMESTAMP,-1))
AND EOMONTH(CURRENT_TIMESTAMP,-1)
);
```
---
### Query C: Top Employer by Announcements

m.posts AS [Number of announcements]
FROM (
SELECT Employer.ID AS Employer_id, COUNT(*) AS posts
FROM Employer
JOIN Job_post ON Job_post.id_employer = Employer.ID
WHERE created_at BETWEEN
DATEADD(day, 1-DAY(EOMONTH(CURRENT_TIMESTAMP,-1)), EOMONTH(CURRENT_TIMESTAMP,-1))
AND EOMONTH(CURRENT_TIMESTAMP,-1)
GROUP BY Employer.ID
) AS m
JOIN Employer ON Employer.ID = m.Employer_id
JOIN City ON City.cities_id = Employer.city_id
JOIN states ON states.ID = City.state_id
ORDER BY [Number of announcements] DESC;
```

FROM Employer
JOIN City ON City.cities_id = Employer.city_id
JOIN states ON states.ID = City.state_id
WHERE Employer.ID <> ALL (
SELECT Employer.ID
FROM Employer
JOIN Job_post ON Employer.ID = Job_post.id_employer
WHERE created_at BETWEEN
DATEADD(day, 1-DAY(EOMONTH(CURRENT_TIMESTAMP,-1)), EOMONTH(CURRENT_TIMESTAMP,-1))
AND EOMONTH(CURRENT_TIMESTAMP,-1)
);
```
---
### Query E: Available Positions by Employer
> *What were the available positions at each employer last month?*
```sql
SELECT Job_post.id_employer AS [Employer ID], Job_post.ID AS [Post ID],
job_title.job_title, Job_post.[description],
Job_category.job_category, job_type.job_type,
Industry.[name] AS Industry, min_salary, max_salary,

AND EOMONTH(CURRENT_TIMESTAMP,-1)
ORDER BY Job_post.id_employer;
