Data Analysis

This excercise should develop a simple analysis cube.

Before beginning we need to add the local service user to the AdventureworksDW Database. Open the security folder for AdventureworksDW and right click on Users.
Select New User. In the login dialog box click on the button by logins and find the local service login. Give the user a name. In the database roles click on the datareader role. Click ok.

Creating a cube

1. Open the Business Intellegence studio
2. Choose FILE /New Project
3. Choose an Analysis Service Project
4. In the Solution Explorer right click on Data Sources
5. Choose New Data Source
6. Next
7. Click the New ...




8. configure the connection



9. Next. Choose Use Service Account



10. Next/Finish
11. In the Solution Explorer Right click on the Data Source View Folder.
12. Choose a new data source view
13. Next
14 Add all the tables and click next



15. Next. Review the tables. Finish
16. In the Solution Explorer right click on Cubes and choose New Cube
16. Next
17. Choose "Use existing tables"
18. Next. Select "FactInternetSales" Next
19. Accept what's there.
20. Next, Next, Next
21. Finish.
22. Right click the cube and select process.
23. A dialog says the cube seems out of date etc, say yes
24. Click Run
25. If all goes well and the cube deploys click close and close again
26. Click Browser
27. Drag fields onto the cube as shown in the illustration below



28. Feel free to add or subtract other fields from the cube

Creating a Simple SSIS (SQL Server Integration Services) Project

this service imports a text file, donor.txt and imports the first and last names into the person table. Before you start make sure you save the Donot.txt file as unicode.
1. Start Visual Studio
2. Go to File, New Project, and then choose Integration Service Project.
3. Cancel the wizard.
4. In the Control Flow Designer window add a dataflow task object from the toolbox
5. Double click it, or click on the Data Flow Tab
6. Add a Flat file Data Source object from the tool box
7. Double click it to get the properties
8. Give the Flat file manager a name, "DonorFlatFileManager" or something
9. Browse to the file Donor.txt
10. Click the check box for first row contains headings
11. Check the preview to make sure you got all the data
12. Now add a new OLEDB Destination object from the toolbox
13. Click on the Flat File Source and connect the green arrow to the destination box
14. Double Click the OLEDB destination object to get the properties
15. Make a new connection manager. It will pop up a dailog
16. Set the server as Localhost, the database as CommunityAssist.
!7. From the drop down list for tables choose Person.
18. Check the column Mappings to make sure that they are correct
19. Run the pagage by going to the menu Debug and choosing run
20. The objects should turn green for success, red for failure
21. If they are red, look at the error messages and correct
22 If they are green, check the database to make sure that it added the records to Person

LINQ Insert Example

Here is the lINQ example I got it to work. It was fairly simple. We needed to Use the "InsertOnSubmit" method. Also to get the foreign key we just needed to point to the first person object. LINQ understands the relationships and gets the key for us.

Remember you have to make a connection to the database. You can use an existing one if you have it. Then you add a LINQ to SQL to the project and drag the tables from the connection in the Server Explorer onto the LINQ designer window.

Here is the XAML file. It may be somewhat different from what we did in class, because I recreated it at home:

Operator Overloading: fraction class

Here is a fraction class that overloads operators to for manipulating fraction objects. It is minimal and could be improved. For one thing it doesn't use a header file interface. (I wrote the whole class in "Fraction.h"). I didn't overload the equality and non equality operators, which I should have.

#include
using namespace std;

class Fraction
{
/************************************
* This class enables a user to do fraction
* math. To do so it overloads several operators.
* It also introduces some error trapping
*******************************************/
//public members
public:
//default constructor
Fraction(){}
//overloaded constructor
Fraction(int numerator, int denominator)
{
SetNumerator(numerator);
SetDenominator(denominator);
}

//start overloaded operators
Fraction operator+ (const Fraction &F2)
{
//this overloads the + operator for two
//fraction objects. It returns the result
//as a fraction object. It gets the greatest
//common denominator--better would be a routine
//that returns the lowest common denominator
//the "this->" pointer points to elements of
//the current class

Fraction temp; //declare an object of the type Fraction
temp.den=this->den * F2.den;
temp.num=F2.den* this->num + this->den * F2.num;
return temp;
}

Fraction operator-(const Fraction &F2)
{
//does the same thing as + but with a -
Fraction temp; //declare an object of the type Fraction
temp.den=this->den * F2.den;
temp.num=F2.den* this->num - this->den * F2.num;
return temp;
}

Fraction operator* (const Fraction &F2)
{
Fraction temp;
temp.den=this->den * F2.den;
temp.num=this->num * F2.num;
return temp;
}

Fraction operator/ (const Fraction &F2)
{
Fraction temp;
temp.den=this->den * F2.num;
temp.num=this->num * F2.den;
return temp;
}

//these next operators are different because they change
//the current instance of Fraction, so they
//return not a third object but a pointer to the
//current instance using *this

Fraction& operator= (const Fraction &F2)
{
this->den=F2.den;
this->num=F2.num;
return *this;
}

Fraction& operator+=(const Fraction &F2)
{
//again we have to get the greatest common denominator
this->num=F2.den * this->num + this->den * F2.num;
this->den=this->den + F2.den;
return *this;
}

Fraction& operator-=(const Fraction F2)
{
this->num=F2.den * this->num - this->den * F2.num;
this->den=this->den * F2.den;
return *this;
}

Fraction& operator*=(const Fraction F2)
{
this->num = this->num * F2.num;
this->den=this->den * F2.den;
return *this;
}

Fraction& operator/=(const Fraction F2)
{
this->num = this->num * F2.den;
this->den=this->den * F2.num;
return *this;
}

//print out the fraction
void PrintFraction()
{
cout << num <<"/" << den << endl;
}

//private members
private:
int num;
int den;

//set functions with some error trapping
//these are private because I don't want
//the user directly access them
void SetNumerator(int n)
{

num = n;
}

void SetDenominator(int d)
{
if (d==0)
throw "Division by 0 error";
den=d;
}
};


Here is some code for testing the fraction. Notice it also uses a try catch black to catch errors thrown by the fraction class:

#include "Fraction.h"

int main()
{
try
{
//uncomment this to see the error thrown
//Fraction e(2,0);
//Declare 3 fractions
Fraction a(1,2);
Fraction b(1,3);
Fraction c; //uses default constructor

//show the current fractions
cout << "Fraction a " << endl;
a.PrintFraction();
cout <<"Fraction b " << endl;
b.PrintFraction();

cout << "\nfraction a + fraction b = ";
c = a + b;
c.PrintFraction();

cout << "\nfraction a - fraction b = ";
c = a - b;
c.PrintFraction();

cout << "\nfraction a * fraction b = ";
c = a * b;
c.PrintFraction();

cout << "\nfraction a / fraction b = ";
c = a / b;
c.PrintFraction();

cout <<"\nfraction a += fraction b = ";
a += b;
a.PrintFraction();

cout << "\nfraction a -= fraction b = ";
a -= b;
a.PrintFraction();

cout << "\nfraction a *= fraction b = ";
a *= b;
a.PrintFraction();

cout << "\nfraction a /= fraction b = ";
a /= b;
a.PrintFraction();


cout <<"Fraction a currently ";
a.PrintFraction();
cout << "\nFraction b currently ";
b.PrintFraction();
cout << "\nAssigning Fraction a = Fraction b. Fraction a = ";
a = b;
a.PrintFraction();

}
catch (char* s)
{
//the char* is a pointer to the strin
//thrown from the set functions
cout << s << endl;
}
char x;
cin >> x;
}

CLR Stored Procedure

It is possible in Sql Server to create a stored procedure in C# or Visual Basic. This is a tutorial/assignment in how to create a very simple procedure in C#:

1. Start a new project in Visual Studio.
2. Under C# choose Database as the kind of project.
3. Then Choose SQLServer Project.
4. If you have existing database connections, it will ask if you want to use one. If one to community assist exits use it. Other wise it will ask what kind of connection you want. Then it will open a new database connection dialog. Fill it in to look like the following:



5. Click OK. A dialog box will open telling you you need to enable clr/sql bugging:



6. Click Yes to continue.
7.Right click on the solution in the Solution Explorer and choose Add/Stored Procedure. Name it "ServiceSummary".



8. Enter this code:

using System;
using System.Data;
using System.Data.SqlClient;
using System.Data.SqlTypes;
using Microsoft.SqlServer.Server;


public partial class StoredProcedures
{
    [Microsoft.SqlServer.Server.SqlProcedure]
    public static void ServiceSummary()
    {
        using (SqlConnection connect = new SqlConnection("context connection=true"))
        {
            connect.Open();
            SqlCommand cmd = connect.CreateCommand();
                cmd.CommandText=
                "Select ServiceName, sum(GrantAmount) as Total "
                + "From [Service] s "
                + "Inner Join ServiceGrant sg "
                + "On s.ServiceKey=sg.ServiceKey "
                + "Group by ServiceName";
                SqlContext.Pipe.ExecuteAndSend(cmd);
        }

      
    }
};

9. When you have the code in, build it.
10. Right click on the project in the Solution Explorer and choose "Deploy."
11. Open Sql Server Management Studio.
12. Look under stored procedures in CommunityAssist. You should see serviceSummary showing.
13. Before you can use the procedure, you must enable clr execution in Sql Server
to do that enter the following SQL:

sp_configure 'clr enabled", 1
Go
Reconfigure
Go

14.Execute the procedure by typing EXEC ServiceSummary in the query window
