Introduction

Structured Query Language (SQL) injection is a code injection technique used in requesting, deleting and updating information from databases. Therefore, it is one of the main web attack mechanism used by hackers to steal data. This attack allows the hacker to inject SQL commands into allowing them access data in a database, as it takes advantage of improper coding in the web applications. This kind of attack bypasses firewalls and endpoint defenses, because web based forms must allow access to databases so as to give some sort of response.

Introduction

Data is the building block of any system in the world today. A repository of such related data is called a database. A relational database organizes the data into tables that are related to each other. For example, in a relational database system, there exists one table that contains the data about cars manufactured by a company and the second table contains the information about car parts. These tables are related to each other, because each car is made up of parts, and each car part can be in one or more cars.
Haley (1991) defines a table as ...

Increase in the use of internet has increased the vulnerabilities of databases for many corporations. Prior to 1970s, much of the research and early work has been in the statistical database security (Thuraisingham 55). The most important accepts in statistical database security involve aggregation and inference (Gollmann 168). Aggregation relates to examining the differences in sensitivity levels of an aggregate computed for a group of values in a database and the sensitivity levels of individual elements. Attackers usually use the differences in sensitivity levels to have access to the sensitive items in the database. When it comes to inference, ...

Abstract
Relational Database Systems (RDBMS) are the most popular database systems today. The relational model of database management emerged from a dynamic database model called DataBase Management System (DBMS). Dbase and FoxPro were the popular DBMS in the 1970’s and 1980’s. RDBMS emerged in the 1990’s. Though RDBMS is a popular form of database management, few appreciate its true potential. Modern applications that allow multiple devices to access and manipulate data are overshadowing RDBMS. NoSQL models such as Hadoop and MapReduce allow document processing which is a feature that the relational model lacks. An in-depth understanding ...

The hardest part of any research project is the analysis. Students often find data analysis difficult because they do not understand which type of tests to use to answer the questions they are asking, don’t know how to interpret the results, or don’t understand how the sample population affects the nature of hypothesis testing (Flick). Given that qualitative data analysis often requires the development of special coding schemes and training of coders to ensure agreement on categories, qualitative research is often viewed as more difficult and less understandable than quantitative research. In Shane, the Lone Ethnographer, the ...

A database management system (DBMS) is a software application that enables one or more users to access data in a database (Rouse).

Business Intelligence and Data Warehouses

The differences between the structure of data warehouse optimized for processing versus relational database optimized for online transactions and summarizing large amounts of data include the following. Data warehouses use partially denormalized schemas so as to optimize performance, but relational databases have fully normalized schemas used to insert, update and guaranteeing data consistency. Data warehouse is updated regularly using techniques like bulk data modification, but relational database is modified by the end user. It is always up-to date and so it reflects the current state of every transaction. A data warehouse query scans millions of rows, for example, finding ...

Database and Network

A database and a data warehouse are somewhat similar in nature as both are databases containing tables and data. But the main difference between the two is that a database records data and a data warehouse responds to major business questions. (Exforsys) Data analysis can be done using a single domain; however, multiple domains are a common feature for many large businesses. A database would only deal with a single business unit, whereas, a data warehouse will deal with and integrate the several business units. Hence, a databases and data warehouses are separately used in businesses.
