A computer, in its most simplified definition, is nothing more than a device that stores, processes, communicates, and manipulates data. Data is at the heart of every computer program, every web site, and even every video game.
The computer has revolutionized modern life by enabling a level of speed and accuracy to handling information that has never before been possible. Computers accomplish this quite simply by following a set of instructions called code.

A DSN (Data Source Name) is an identifier that is used to store information relating to a database connection. DSNs can store a database’s name and server location, the directory that is used to store offline content, the database driver, and the user’s ID and password. DSNs can be used for a wide variety of database applications, such as SQL databases and FTP connections.
How DSN Works
A DSN is simply a file that contains all information regarding a particular database. DSNs

ODBC (Open Data Base Connectivity) is an interface to access databases via SQL queries. ODBC can be used as an access tool to various databases such as MS-Access, dBase, DB2, Excel, and Text. Through these Call Level Interface (CLI) specifications of the SQL Access Group, the OBDC allows a neutral way of accessing the data stored in personal computers and various databases. It was first created by Microsoft and Simba Technologies. ODBC 1.0 was initially released in September 1992, and eventually

SQL (Structured Query Language) is the most common standardized database language used to create, retrieve, access, modify, controland manage relational databases. SQL is a querying language exclusively designed for controlling data and managing databases effectively.
SQL was originally developed by IBM (International Business Machines Corporation) in the 1970's for their DB2 RDBMS. The team of developers included Andrew Richardson, Donald C. Messerly and Raymond F. Boyce. This first versi

Most people are familiar with terms like data warehousing, data mining, and data cleansing, but fewer people are familiar with data mart. A data mart is a subsection of a data warehouse that deals with specific information. Much like the chapters of a book, a data mart contains related information that deals with the same subject, but may also be divided into its own categories. In this article, we will be exploring data marts and data mart software that allow you to extract information from a d

A stored procedure is, in simplest terms, a command. Stored procedures are used to perform a wide variety of tasks on a computer and can be pre-programmed with any number of parameters or variables. While stored procedures are always used to interact with a database, they can be used for many different applications, such as use in employee databases, restaurant or retail records, or even in regular websites.
How a Stored Procedure Works
A stored procedure can be created by using any standa

Database replication is the creation and maintenance of multiple copies of the same database. In most implementations of database replication, one database server maintains the master copy of the database and additional database servers maintain slave copies of the database. Database writes are sent to the master database server and are then replicated by the slave database servers. Database reads are divided among all of the database servers, which results in a large performance advantage due t
