Any solution for NoSQL, local database, C#, compatible with Unity?
I want to use a noSql database to store some data on local disk. I don't want a WEB server, or to install any service database like MySQL/MSSQL Server, and no junk sql code like "select a.a, b.a from a inner join b..." messing with my code. What could I use?

Have a look at scriptable objects, they are like data container objects. Should really be good enough for what you're looking for.
I've found one called SIAQODB: "...a NoSQL embedded object and document database engine that currently runs on .NET, $$anonymous$$ono$$anonymous$$ac, Universal Windows Platform (UWP), Xamarin.iOS, Xamarin.Android, Xamarin.$$anonymous$$ac and Unity3D. "
It's free if you store less than 100 objects per type/table, so it works for what i need. There's a Database $$anonymous$$anager that unfortunatelly I can't run to edit the database outside Unity (error with x86 / x64 version of the database file and the manage application), I'm looking for a solution on the siaqodb forum.
The basic usage is:
using Sqo;
class $$anonymous$$yDatabase : $$anonymous$$onoBehaviour
{
void Start()
{
var db = new Siaqodb(Application.dataPath + @"\databaseFolder\");
db.StoreObject(new Foo("$$anonymous$$az", 26);
print(db.LoadAll<Foo>().Count);
}
}
public class Foo
{
public string Name {get;set;}
public int Age {get;set;}
public Foo(string name, int age)
{
this.age = age;
this.name = name;
}
}
But I'm still looking for other solutions to compare. I will take a look about Scriptable Objects ( I've never had to use them before).

Hi @KazYamof,
I'm the author of MarcelloDB (http://marcellodb.org) which is an embedded nosql database. It should be a good fit for your use case.
Below is the example as for siaqodb, ported to marcellodb.
class MyDatabase
{
public class Foo
{
public int ID { get; set; }
public string Name { get; set; }
public int Age { get; set; }
public Foo (int id, string name, int age)
{
this.ID = id;
this.Age = age;
this.Name = name;
}
}
void Start ()
{
var dataPath = Application.dataPath + @"\databaseFolder";
var session = new MarcelloDB.Session(new MarcelloDB.netfx.Platform(), dataPath);
var foos = session["data"].Collection<Foo, int>("AllTheFoos", f => f.ID);
//persist
foos.Persist(new Foo(1, "Kaz", 26));
//enumerate
foreach(var f in foos){
}
//find individual item:
foos.find(1);
}
}
Hi @markmeeus, I'm trying $$anonymous$$arcelloDB in my Unity app, but it is a pcl (so it targets .net 4 or higher) do I have to refactor it to compile .Net 3.5 or should it "just" work if I add the dll as a plugin?
regards!
