...Databases are powerful tools that can provide businesses with an edge over the competition. Databases can help keep track of, inventory, billing, payroll, phone numbers, and much more. Databases are essential for almost every company in today's business world. The company that I used to work for custom built their database in-house to suit their business needs. The company uses Oracle, SQL, and Microsoft Access. The company asked me to develop a helpdesk database using SQL and Microsoft Access. The server-based database that the company uses is the Structured Query Language (SQL) Server to run security. One of the draw backs of the server is that it has many security problems that constantly need to be patched. These patches are important to keep integrity of the data and security and should be scheduled to be applied on regular bases. Microsoft Access is a relational database management system which, allows users to create, edit, and maintain sophisticated databases. When developing the helpdesk database I found the wizard to be easy to use and helpful when creating the tables, data entry screens, display screens, and generating reports. The visual capabilities are user friendly and the user does not need to have programming experience. The wizard is an excellent internal tool to help the user with creating data entry forms and display screens. Microsoft Access also has its security problems. Microsoft Access is restricted to how much data can be stored before needing to...

This small business currently covers all South Florida and part of the Treasure Coast. The Countertop Guys uses a SQL Database to keep up with the manufacturing, customer service and work order processing. The database application used is Filemaker Pro and this application enables the users to keep track of work orders status, material daily production reports among others. Microsoft SQL Server also allows user-defined composite types (UDTs) to be defined and used. It also makes server statistics available as virtual tables and views (called Dynamic Management Views or DMVs). In addition to tables, a database can also contain other objects including views, stored procedures, indexes and constraints, along with a transaction log. A SQL Server database can contain a maximum of 231 objects, and can span multiple OS-level files with a maximum file size of 220 TB. The data in the database are stored in primary data files with an extension .mdf. Secondary data files, identified with an .ndf extension, are used to store optional metadata. Log files are identified with the .ldf extension. Storage space allocated to a database is divided into sequentially numbered pages, each 8 KB in size. A page is the basic...

Basically a library contains documentation for reference, research and learning purposes with a variety of fields to look into. Some may also have archived materials that are still being used. Current libraries have a section where you can access materials like newspapers to catch up with news updates. This database will use a MYSQL environment to manage the data related to the library and Delphi in designing the interface Problems and constraints The existing library has a category of sections from which reference materials for research and learning can be obtained. Unfortunately no systematic sorting has been done to categorize books in each section. This makes it some worth difficult and time consuming to find a specific book of interest within the sections Objectives of the database environment The objectives of the database environment are enlisted below * Provide an all-in-one system for accessing reference materials * Develop a system that will store user details and item details * Create an easy to understand and friendly environment * Develop a system that can replace the manual library management system * Provide borrow and return records * Provide user access levels(i.e...

...USE OF DATA ANALYSIS IN MODELING Use of Data Analysis in Modeling Michael Matthews CIS 331: System Modeling Theory Strayer University Mark O’Connell, PHD March 5, 2013 The term “model” refers to a process of creating a representation of reality and working with this simplified representation in order to understand or control some part of the world (Barker, Powell 2004 pg. 11). A model can be used in varies ways such as business plains, forming a database, or building a structure. It can also be formed mentally, visually, and mathematically especially by data analysis. Data analysis is the process of raw data measured in order to determine the means based on that data. Although, data is relevant in producing a model, it is only used to provide general perspective of information, not to form a solution. By determining this objective, I will demonstrate the use of data analysis to form a model and the advantages and disadvantages that come with it. The techniques of a model are used constantly to understand the world and to predict the outcomes and actions. For example, a mental model come into play when one manager has to decide is hiring an older worker beneficial to the company. Another manager suggests that hiring older workers is a good idea because they bring valuable experience to the job. This mental model is the basis of decision making, one action forming an outcome (Barker, Powell 2004). The decision that is made, the advantage and disadvantage of hiring...

...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...
