In this video demonstration I explained how data is stored in Databases.
Databases rank among the most significant structural elements of the World Wide Web nowadays. Lying in the basis of the majority of the content-driven websites and applications, databases serve a special mission – to provide a well-organized mechanism for data manipulation. The database approach in website/application development now rules the web by offering a quick and automated way for the information to be stored, managed, deleted or retrieved. Databases’ powerful set of capabilities has determined the introduction of dynamic websites, which has opened a new page in the evolution history of the web.
A database is a table consisting of columns (fields) and rows (records) where each column contains a specific attribute and each row features a certain value for the corresponding attribute. The number of columns within a single table depends on how many different types/categories of information we need to store within a database, while the number of rows is defined by the quantity of the objects that have to be introduced categorized records for. This kind of simple organization of the data in database tables allows for a computer program to quickly select and handle the necessary pieces of information.
