Effective use of LINQ2SQL
I am a LINQ2SQL fan, however, EF is also coming along. In my web application project I created various LINQ2SQL queries in different functions. Like:

    Function A()
    {
    // LINQ2SQL QueryA accessing Database ABC
    }
    Function B()
    {
    // LINQ2SQL QueryB accessing Database ABC
    }
    Function C()
    {
    // LINQ2SQL QueryC accessing Database ABC
    }
    Function D()
    {
    // LINQ2SQL QueryD accessing Database ABC
    }
    Function E()
    {
    // LINQ2SQL QueryE accessing Database ABC
    }

As you can see, my app is not efficient at all. I want to make this efficient by querying my DB only once and then fetching from it in different functions. What should be the better implementation for this? 

Thanks!
