## Pendency System

### Machine Coding interview

- Pendency is a system that is able to track counts of in-flight/in-progress entities.  

- The system is told when to start tracking a particular entity, and when to stop. And at any point the system can be asked how many entities are in-progress (or in-flight). The system is expected to give this count, as fast as possible  

- [Pendency System - Complete Problem Statement](https://github.com/alpha74/PendencySystem_JavaSpringBoot/blob/main/docs/problem_statement.md)

```

This is not the Code in actual interview.

Done as a practice for this problem statement.

Hence, design is done more thoughtfully.

```

### Code/Run

- Java8, Maven, IntelliJ(Community)

- Driver class `TrackingServiceTest.java`

- All necessary code in `src` dir

### Understanding the Working

- To understand the working, read Problem Statement thoroughly

- Then explore `dir` in this order:

  1. Entities

  2. Repository

  3. `TrackingServiceTest.java`

  4. Then, deeply go through Services
