# Activeohos

Activeohos : Activeohos is an active record style ORM (object relational mapper). What does that mean exactly? Well, Activeohos allows you to save and retrieve SQLite database records without ever writing a single SQL statement. Each database record is wrapped neatly into a class with methods like save() and delete().

Activeohos does so much more than this though. Accessing the database is a hassle, to say the least. Activeohos takes care of all the setup and messy stuff, and all with just a few simple steps of configuration.

# Activeohos includes :
* Inserting, Deleting and updating database.
* Setting up the database.
* Create required database and perform operations on it.
* Raw queries, Delete queries.
* Database Encryption.

# Usage Instructions

1. The following core classes are the essential interface to Activeohos:
	ActiveHarmony - Hepls in initializing the database with given configuration
	Annotation: Manages resolving the @column, @Table annotation
	Model - Defines the methods for creating, managing the database

2. The steps to initialize the database and Activeohos:
	-> make MyApplication(it will change as per your application name) to extends Application class
		eg: public class MyApplication extends Application {} //This helps in initialization and dispose of the ActiveHarmony

-> Load libsqlcipher.so
    
		SQLiteDatabase.loadLibs(this);
        
		NOTE: Keep application name to "MyApplication"(libsqlcipher.so dependency)
	
	-> Create Class which extends Model class and define the required columns in table.
		For example:
        
		@Table(name = "Details", id = "_id")
		public class Details extends Model {
		@Column(name = "Age")
		private String age;

@Column(name = "id")
		private long id;
		}
		
	-> Create new Configuration.Builder object, add the required Model class and set the package name of the sample app
    
		Configuration.Builder configurationBuilder = new Configuration.Builder(this);
        configurationBuilder.addModelClasses(Details.class);
        configurationBuilder.setPackageName("com.activeharmony.sample"); // use your sample app package name
        ActiveHarmony.initialize(configurationBuilder.create());
		
3. Please refer the sample app for the CURD operation's

# Installation Instructions

1. For using Activeohos module in your sample application, add below dependencies in "entry" module to generate hap/har:

Modify entry build.gradle as below :
    
	```
	dependencies {
    	implementation project(path: ':library')
		implementation 'io.openharmony.tpc.thirdlib:ohos-database-sqlcipher:1.0.2'
	}
	```

2. For using Activeohos in separate application, add the below dependencies and include "Activeohos.har" in libs folder of "entry" module  :

Modify entry build.gradle as below :
    
    ```
	dependencies {
		implementation fileTree(dir: 'libs', include: ['*.har'])
		implementation 'io.openharmony.tpc.thirdlib:ohos-database-sqlcipher:1.0.2'
	}
    ```

3. For using Activeohos from a remote repository in separate application, add the below dependencies  :
Modify entry build.gradle as below :
        
	```
    dependencies {
        	implementation 'io.openharmony.tpc.thirdlib:Activeohos:1.0.0'
            implementation 'io.openharmony.tpc.thirdlib:ohos-database-sqlcipher:1.0.2'
    }
	```
