...Q2: How are database application systems developed? A database application system consists of a database, a DBMS, and one or more database applications. A database application consists of forms, reports, queries, and possibly application programs. A database application system encompasses one or more application programs and works at a more macro level; application programs, on the other hand, focus on smaller components and work on smaller pieces of data management. The major steps in developing an application system are to interview users and develop requirements for the new system; this includes analyzing existing forms, reports, queries, and other user activities, as well as determining the need for new forms, reports, and queries. They can then use this to create a data model (logical representation of the structure of the data), which is then transformed into a database design. After that, the design is implemented in a database, which is then filled with user data. Users are especially important in the first step of the process, where incorrect, insufficient, or inaccurate user input will result in a poorly designed database that will not fill the voids of current systems. Q5: What is the users’ role? The major role for users in the development state is in the first step; users are the final judges as to what data the database should contain and how the records in that database should be related to one another. During the data modeling stage, the structure...

...about Database Testing Presented by: Mary R.Sweeney Exceed Technical Training & Consultation Copyright Sammamish Software Services 2003. All rights reserved. 1 Today’s complex software systems access heterogeneous data from a variety of backend databases. The intricate mix of client-server and Web-enabled database applications are extremely difficult to test productively. Testing at the data access layer is the point at which your application communicates with the database. Tests at this level are vital to improve not only your overall test strategy, but also your product’s quality. In this presentation you’ll find out what you need to know to test the SQL database engine, stored procedures, and data views. Find out how to design effective automated tests that exercise the complete database layer of your applications. You’ll learn about the most common and vexing defects related to SQL databases and the best tools available to support your testing efforts. Copyright Sammamish Software Services 2003.

...Database Dictionary.com defines database as “a systematically arranged collection of computer data, structured so that it can be automatically retrieved or manipulated”. In today’s business, organizations run on data that have been processed into information and knowledge. That information is used by managers to apply to business problems and opportunities. Furthermore the data is transformed into knowledge and solutions in many different ways after detail analysis. Because data and information are processed in several stages and often in several places, they are frequently subject to problems and difficulties. Managing data in organizations is difficult for many reasons, so organizations in the effort to manage all of the data, developed databases to organize all of the collection. These databases are managed using database management systems, and by utilizing different applications. In our organization, we do have a database that we use for our data collection and analysis and storage of all the data we collect. We also use several applications in the daily operations of our business which I will explain further in this paper. Our organization is currently using several applications to make our processes more precise, effective and efficient. Currently, our organization is using a Sybase SQL database as the main database for all of our business functions. This database delivers extreme transaction processing and access to mission critical information...

...A Survey of SQL Injection Defense Mechanisms Kasra Amirtahmasebi, Seyed Reza Jalalinia and Saghar Khadem Chalmers University of Technology, Sweden akasra, seyedj, saghar{@student.chalmers.se} Abstract SQL Injection Attack (SQLIA) is a prevalent method which makes it possible for the attackers to gain direct access to the database and culminates in extracting sensitive information from the firm’s database. In this survey, we have presented and analyzed six different SQL Injection prevention techniques which can be used for securing the data storage over the Internet. The survey starts by presenting Variable Normalization and will continue with AMNESIA, Prepared statements, SQL DOM, SQLrand and SQLIA prevention in stored procedures respectively. that determining whether a SQL statement is allowable or not is done by checking the existence of normalized statement in the ready-sorted allowable list. 2.1. Background Many web pages ask users to input some data and make a SQL queries to the database based on the information received from the user i.e. username and passwords. By sending crafted input a malicious user can change the SQL statement structure and execute arbitrary SQL commands on the vulnerable system. Consider the following username and password example, in order to login to the web site, the user inputs his username and password, by clicking on the submit button the following SQL query is generated: SELECT * FROM user_table WHERE user_id = ‘john’ and password...
