## Dao & Norm
* Dao - A ColdFusion library for easy and db agnostic CRUD interaction and Linq style query building.
* Norm (Not ORM) - A dynamic Object Mapping layer built on top of DAO that provides oData support and ORM style object interactions (load, save, relate entities, etc...).

## Elevator Pitch
Dao/Norm is a duo of libraries that provide a simple yet full featured interface to perform script based queries as well as adds extended functionality such as ORM (with easy and dynamic relationships), oData (Consume/Produce), LINQ style queries and more.  Basically it is the data interaction ColdFusion/Railo/Lucee should have come with out of the box.

In short, the goal of this library is to allow one to interact with the database in a DB platform agnostic way, while making it super easy.

## Supported databases
Dao supports **MySQL**, **MSSQL**, and **SQLite** via connector components (`database/mysql.cfc`, `database/mssql.cfc`, `database/sqlite.cfc`) that implement `IDAOConnector`. Use the `dbtype` argument when creating the DAO (e.g. `new database.dao( dsn = "mydsn", dbtype = "sqlite" )`) or rely on auto-detection when the datasource is configured. Tests and connector logic must remain compatible with all three; avoid changes that assume a single database.

## Requirements
- **Runtime:** Lucee 4.x, 5.x, 6.x, or Adobe CF 11+
- **Lucee 6:** Requires **Java 11 or later**. CommandBox uses your system `java`; if you see `org.lucee.commonmark` / `osgi.ee; (version=11)` when running `box start`, install a newer JVM and point the project at it (see below).

### Using Java 11+ with this project (Lucee 6)

1. **Install OpenJDK 17** (Ubuntu/Debian):
   ```bash
   sudo apt-get update && sudo apt-get install -y openjdk-17-jdk
   ```

2. **Make it the system default** so CommandBox (and everything else) uses Java 17 globally:
   ```bash
   sudo update-alternatives --set java /usr/lib/jvm/java-17-openjdk-amd64/bin/java
   ```
   Confirm with `java -version` (should show 17.x). No per-project or per-shell setup needed.

## Installation
### Manual
Clone this repo and copy the "database" folder `(/database)` into your project (or into the folder you place your components)
### CommandBox
`box install dao`

### Examples
#### DAO
```ActionScript
dao = new database.dao();
dao.update("sometable",form);
```
```ActionScript
function getUsers(){
	// normally injected or in applicaiton scope
	dao = new database.dao();
	return dao.read(
		sql = "
			SELECT fname as firstName, lname as lastName
			FROM Users
		",
		returnType = "array"
	);
}
writeOutput( getUsers() );
```
Output:
```JavaScript
[
	{"firstName":"Jill","lastName":"Smith"},
	{"firstName":"Joe","lastName":"Blow"},
	{"firstName":"John","lastName":"Cash"}
]
```
#### LINQ
```ActionScript
dao.from( "eventLog" )
		.where( "eventDate", "<", now() )
		.andWhere( "eventDate", ">=", dateAdd( 'd', -1, now() ) )
	.run();
```
#### Norm
```ActionScript
User = new database.Norm("user");
User.loadByFirstName("joe");
User.setStatus("online");
User.save();
```

## Testing

**Which database are tests using?** The first line of test output is `Database: sqlite` (or `mysql` / `mssql`). To change it, set **`this.datasource`** in `tests/Application.cfc` to **`dao_sqlite`**, **`dao_mysql`**, or **`dao_mssql`** (all three are defined in the same `this.datasources` block). See [docs/test-database.md](docs/test-database.md).

## Testing with MySQL or MSSQL (Docker)

A Docker Compose file is included to run MySQL and/or MSSQL for tests. Start with `docker compose up -d` (or `docker compose up -d mysql` / `docker compose up -d mssql`). See [docs/docker-mysql.md](docs/docker-mysql.md) and [docs/docker-mssql.md](docs/docker-mssql.md) for connection details and how to point the test app at each database.
