# Tugas Besar II Manajemen Basis Data 2022 - Concurrency Control
Concurrency control simulation is a simulation of how DBMS works. There are consist of two protocls, Optimistic Concurrency Control and Simple locking using only exclusive locks.

## Requirement list and Installation
1. Install python [here](https://www.python.org/)
2. clone the repository using `git clone https://github.com/IloveNooodles/concurrency-control`
## Usage
This program uses argparse so you can read the full command here
```
usage: main.py [-h] {simple,optimistic} [pathfile]
Concurrency Control Protocol Implementation
positional arguments:
{simple,optimistic} choose concurrency control protocol, s[imple] and o[ptimistic]
[pathfile] path file for the testcase or input
options:
-h, --help show this help message and exit
```
To run the program you can specify the path and protocol you want to use for example `python main.py simple test/tc1.txt` to run `tc1.txt` with simple locking
In simple mode The program will ask prompt if you want to enable the deadlock prevention
```
>> Starting simple locking protocol
>> Do you want to activate deadlock prevention? (y/n)
```
## Valid input
Valid input are
- `C[number]`
- `R[number](alphabet)`
- `W[number](alphabet)`
Here are example of valid input
`R1(X); R2(Y); R1(Y); C1; C2`
After each action must be separated with ; and but no ; in the EOF
