# Installation

```julia

] add StructDatabaseMapping

```

# Compatibility

* [SQLite](https://github.com/JuliaDatabases/SQLite.jl)

* [PostgreSQL](https://github.com/invenia/LibPQ.jl)

* [Redis](https://github.com/JuliaDatabases/Redis.jl)

* Possibly every relational DB that supports the DBInterface

# Simple example

[For a better example see the docs](https://lucianolorenti.github.io/StructDatabaseMapping.jl/dev/example.html)

```julia

using StructDatabaseMapping

using Dates

using SQLite

using Test

mutable struct Author <: Model

    id::DBId{Integer}

    name::String

    age::Integer

    date::DateTime

end

function Author(;id::Union{Integer, Nothing} = nothing,

                name::String="",

                age::Integer=0,

                date::DateTime=now())

    return Author(id, name, age, date)

end

mutable struct Book <: Model

    id::DBId{String}

    author::ForeignKey{Author}

    data::Dict{String, Integer}

end

function Book(;id::Union{String, Nothing}=nothing,

               author::Foreign{Author}=Author(),

               data::Dict{String, Integer}=Dict())

    return Book(id, author, data)

end

DB_FILE = "test_db"

using SQLite

creator = ()->SQLite.DB(DB_FILE)

mapper = DBMapper(creator)

register!(mapper, Author)

register!(mapper, Book)

configure_relation(mapper, Book, :author, on_delete=Cascade())

create_table(mapper, Author)

create_table(mapper, Book)

author = Author(name="pirulo", age=50)

insert!(mapper, author)

```
