## Current Features for database package

+ Establishes & Maintains database connection across program life cycle
+ Multiple database support via simple repository model
+ Run migration on connection to assure database is at correct version

## How to use

##### To Manually migrate to the latest database you can run the "dbmigrate" helper in the cmd folder

This will parse and run all migration files in your $GoCryptoTrader/database/migrations

_This is also run from the bot when a connection is established to the database_

```sh
go run ./cmd/dbmigrate
```
A Makefile command has also been added for this
```sh
make db_migrate
```

##### To create a new migrate file you can also run the same command with the -create "migration name" flag

```sh
go run ./cmd/dbmigrate -create "alter some table"
```

##### Adding a new model

+ Create Model in github.com/thrasher-corp/gocryptotrader/database/models directory

##### Adding a Repository
+ Create Repository directory in github.com/thrasher-corp/gocryptotrader/database/repository/
+ Create a base Repository interface with any required Methods
+ Create a per driver implementation of the Repository that implement all required methods to match the interface
