 Assignment 5 - Transactions

 

Objectives

 

Demonstrate understanding of ACID and transactions

Create a transaction that meets these requirements

 

Assignment

 

ACID is a set of rules, not an algorithm. For a database system to implement ACID requirements it must implement it using an algorithm 

 

You will submit a paper with information on how SQL Server implements transaction management to meet the ACID requirements. In addition you will create a transaction for the supplied database.

 

User Credit Database

 

Table - Users

- UserId

- UserName

- UserInformation (this can be emails, address, etc...)

 

Table UserAccount

 - UserAccountId

 - UserId

 - AccountType

 - CreditBalance

 

Table - Transactions

- TransactionId

- UserAccountId

- TransferAmount

- CreditOrWithdrawal

- TransferCode (Reason for transaction - can be null)

- TransactionDateTime

 

 

The transaction must transfer credits from User Account to another given; UserId, UserAccountIdFrom, UserAccountIdTo, TransferAmount, TransferCode. Note that when transferring credits there should be a transaction entry for the from account and another for the to account.

 

Submit the assignment in pdf or doc format.

 

Information

 

You will want to Google Search on implementing database ACID

 

Estimated Completion Time

 

5-10 hours to watch video, research requirements - and write the paper and stored procedure.

 

Supporting Lectures 

 

Lecture - Getting Started with Transactions in T-SQL

 

Questions and Answers

 

This will require some web research into the algorithms used.

 

External Resources

 

Web sources are sufficient for this assignment, you will need to do some product research (Post-Gre, Oracle, IBM Progress, MySQL, are all examples of database that you can use for comparison)

 

Grading Criteria

 

The paper should be a well written document with no grammar errors and represents your research and knowledge of ACID and specific implementations to meet the requirements of ACID in transaction management.
