How LiteDB Works

• database structures overview (pages, services)
  • Document Growth
  • file format
  • database info
• transactions
• herança LiteDatabase
• user versions
• concurrence
  • avoid dirty read
  • concurrent read/write
  • lock database / transaction
  • windows locks - 250ms
• journaling
• recovery
  • on open database
  • journal file
• limit and sizes (page-size, index-per-collection, document-size)
• connection string
• thread safe?

Repository pattern

LiteDB architeture is ideal to work in repository pattern data access. You can write a class that inheriths LiteDatabase and add your collections as properties:

public class MyDB : LiteDatabase
{
    public MyDB()
        : this (@"C:\Temp\mydatabase.db")
    {
    }
    
    private LiteCollection<Customer> _customers;
    
    public LiteCollection<Customer> Customers
    {
        get { return _customers ?? (_customers = this.GetCollection<Customer>("customers")); } 
    }
    
    private LiteCollection<Order> _orders;
    
    public LiteCollection<Order> Orders
    {
        get { return _orders ?? (_orders = this.GetCollection<Order>("orders")); } 
    }
    
}

// later...

using(var db = new MyDB())
{
    var cust = new Customer { Id = 123, Name = "John Doe" };
    
    db.Customers.Insert(cust);
    
    db.Customers.Delete(123);
}
