This portfolio provides examples of Vera Vaitsiuk's skills with SQL Server 2008, including logical and physical database design, T-SQL queries, stored procedures, triggers, SSRS reports, and SSIS packages. Specifically, it highlights work with the ApressFinancial database - designing the schema and implementing queries, functions, procedures, and a trigger. It also includes SSRS reports generated from the ApressFinancial and AdventureWorks2008 databases and an SSIS package that extracts data from AdventureWorksDW to an Excel file.

2. Introduction
Hello!
My name is Vera Vaitsiuk.
This portfolio is designed to give examples of my development skills with SQL Server 2008. These
examples are taken from project assignments completed during the program “Systems Software , SQL
Application” at American Advanced Institute of Technology in Southampton, Pennsylvania.
This program is very deep 9 months course that covers everything about SQL Server 2008 - SQL
Server Management Studio, logical and physical database design and development, normalization,
security, backup, restore, data extraction, data conversion, writing T-SQL queries, sub-queries, stored
procedures, user-defined functions, cursors and views, SQL joins, triggers, SSRS, SSIS, import, export
data, creating packages, scheduling maintenance plan, SQL Agent, database mail, high availability
(windows clustering, log shipping, database mirroring), replication.
I am confident that from this portfolio, you'll be assured of my skills in SQL development.

4. ApressFinancial database
ApressFinancial database was an example of my T-SQL development skills.
ApressFinancial database is a database for a personal or corporate financial tool.
This database holds information to keep track Customers, Financial Products
(accounts, shares, life insurance), Transactions in one database.
In additional to tables and columns development creating relationships and indexes,
I will demonstrate knowledge of advanced T-SQL using sub-query, aggregation
functions, creating functions, stored procedure that were used to create customers,
trigger to update information about transactions and SSRS.
The database diagrams follows. This detailed structure of the database shows what
information was captured.

6. ApressFinancial database - Select Data
This is T-SQL code sample that will list the share's ID, share description, min and max
prices of shares. The report is sorted in descending order based on the min price. In this
example , shares will only be listed if they have min price greater than 1.

7. ApressFinancial Database – Select Data. This is T-SQL code sample that will list all
from ShareDatails.Shares table. The report is sorted in ascending order based on the
ShareID. This example shows how to combine a sub-query and an aggregation to produce
the list of ShareIds that form the IN:

8. ApressFinancial database – Select Data. In this example I will use a CASE statement
to add up Customer's Transaction Details for the month of August. If the Transaction Type
is 0, then this is a Debit; if it is a 1, then it is a Credit. By using the SUM aggregation, we can
add up the amount. We get two rows in the result set: one for debits and one for credits.

9. ApressFinancial database – Creating Function. A Scalar function to calculate
Interest. This function will calculate the amount of interest from a defined rate and will use
two dates for the number of days the interest shall last.

10. ApressFinancial database – Creating Store Procedure. This is T-SQL code sample
for creating stored procedure for inserting customers into the Customers table.

11. Apress Financial database – Creating Trigger.
This is T-SQL code sample for creating a trigger. The purpose of this is to change a
Customer's account balance when a financial transaction occurs as defined by an INSERT
in the TransactionDetails.Transactions table. We want to change balance AFTER the row
has been inserted into TransactionDetails.Transactions table.

12. ApressFinancial database - Testing trigger.
If we insert a cash withdrawal to the transaction types. We will list the customer balance
before executing the INSERT into the TransactionDetails.Transactions table, and then we
will add the row and look at the balance again to show that it has changed. The following
code will insert a withdrawal of 200$ from CustomerID 1's account:

13. ApressFinancial database – SSRS.
In this slide we will call the report
Designer within Business Intelligence
Development Studio to produce a simple
report containing the list of transactions
from the
TransactionDetails.Transactions table.

14. AdventureWorks2008 database – SSRS. This report uses AdventureWorks2008 Data-
set. The report shows Sales Analysis for each subcategory of products for each quarter of
the year.

15. AdventureWorksDW database – SSIS. In this sample I will walk through creating a
SSIS package from scratch. As an example I will generate an Excel spreadsheet that can be
used to manually enter a sales forecast by city and state. The city and state information will
be extracted from the AdventureWorksDW database and output to an Excel spreadsheet.
The sales department could use this spreadsheet to enter the forecast.

16. AdventureWorksDW database – SSIS. We can open the Excel spreadsheet that the
package created and see the following (only a portion of the spreadsheet is shown).
This spreadsheet shows the columns from our query plus the Forecast column which I
added with the Derived Column task.
