        # ObjectRelationalMapper

## Overview

A simple ORM, influenced by Hibernate and the Django ORM, for generating MySQL-like queries, developed using annotations, aspects and the Java reflect package.

## Details

Entities must have the @Table(), and attributes the @Column() annotation.


Before saving entities and adding elements to manyToMany relationships, aspectJ methods intercept the call and perform validation.


An entity must have strictly one @ID field.


@ManyToMany fields must be of type ArrayList\, and elements being added are checked for type compatibility (T).

  

#### Supported annotations:

* @Table(name)

* @Column(name, required, notNull)

* @Id

* @IntegerField

* @CharField(maxLength)

* @MappedSuperclass

* @ForeignKey

* @ManyToMany

## Example

### Defined entities:

![Alt text](images/1.png?raw=true "")



![Alt text](images/2.png?raw=true "")



![Alt text](images/3.png?raw=true "")



![Alt text](images/b4.png?raw=true "")



### Saving (inserting) entities:

![Alt text](images/5.png?raw=true "")


### Console output:

![Alt text](images/b6.png?raw=true "")

## Sidenote

This project was an assignment as part of the course - Advanced Java programming during the 7th semester at the Faculty of Computer Science in Belgrade.
