Testlet 1 Scenario 1
Application Information
Your company receives invoices in XML format from customers. Currently, the invoices are stored as files and processed by a desktop application. The application has several performance and security issues. The application is being migrated to a SQL Server-based solution. A schema named InvoiceSchema has been created for the invoices xml.
The data in the invoices is sometimes incomplete. The incomplete data must be stored and processed as-is. Users cannot filter the data provided through views.
You are designing a SQL Server database named DB1 that will be used to receive, process, and securely store the invoice data. A third-party Microsoft .NET Framework component will be purchased to perform tax calculations. The third-party tax component will be provided as a DLL file named Treytax.dll and a source code file named Amortize.cs. The component will expose a class named TreyResearch and a method named Amortize(). The files are located in c:\temp\.
The following graphic shows the planned tables:
You have a sequence named Accounting.InvoiceID_Seq.
You plan to create two certificates named CERT1 and CERT2. You will create CERT1 in master. You will create CERT2 in DB1.
You have a legacy application that requires the ability to generate dynamic T-SQL statements against DB1. A sample of the queries generated by the legacy application appears in Legacy.sql.
Application Requirements
The planned database has the following requirements:
All stored procedures must be signed.
The original XML invoices must be stored in the database.
An XML schema must be used to validate the invoice data.
Dynamic T-SQL statements must be converted to stored procedures.
Access to the .NET Framework tax components must be available to T-SQL objects.
Columns must be defined by using data types that minimize the amount of space used by each table.
Invoices stored in the InvoiceStatus table must refer to an invoice by the same identifier used by the Invoice table.
To protect against the theft of backup disks, invoice data must be protected by using the highest level of encryption.
The solution must provide a table-valued function that provides users with the ability to filter invoices by customer.
Indexes must be optimized periodically based on their fragmentation by using the minimum amount of administrative effort.
Usp_InsertInvoices.sql
Invoices.xml
All customer IDs are 11 digits. The first three digits of a customer ID represent the customer’s country. The remaining eight digits are the customer’s account number.
The following is a sample of a customer invoice in XML format:
InvoicesByCustomer.sql
Legacy.sql
CountryFromID.sql
IndexManagement.sql
