One of the primary reasons for using a relational database is that it makes updating and maintaining website content easier. Often within a website, the same piece of information will be included in more than one location, so if that information needs to be amended or updated, the same editing process must be carried out multiple times. With a relational database, a data item can be listed once and then read from the same location whenever it is required within the site. This means that information only needs to be updated in this one place and the changes will filter throughout the site.
Consistency
Relational databases can increase consistency in the way website content is both structured and presented. When data is kept in a database, items within the same category will be listed within the same table and a server-side scripting language such as PHP or ASP will pull the data for presenting within the site pages. The data will normally be structured in HTML and styled in CSS (Cascading Style Sheets), using the same structures for everything within a category of data, making the site structure and appearance uniform and therefore more user friendly.
Reliability
Database systems offer a reliable way to store website content and are less likely to become corrupted than static HTML files. Most Web database systems such as MySQL can be easily backed up to protect against data loss. Many Web database systems can also provide secure functions, preventing data updates from being carried out by anyone who is not authorized. For corporate needs, there are powerful database systems such as Oracle that can provide extensive levels of security.
Dynamic Functions
Within Web development, sites are described as being either static or dynamic. Sites built using server-side scripting on top of a relational database are dynamic, which is in contrast with static sites where the content is included within HTML files that are simply viewed on request by visitors. Database-driven sites are dynamic because the pages are only built when a visitor requests them, with the HTML content being written by the server-side program according to whatever is in the database. This means that relational databases make a site more fluid and changeable, potentially offering a unique user experience with each visit.
Separating Content From Style
Websites are generally more usable to people when content and style are kept separate within the code. The content of a site is the data, text and other media displayed within it, and the style is the formatting rules (for example in CSS), determining how this content should be displayed. Keeping content and style separate allows websites to adapt to different environments and lets users tailor the presentation to suit them. Database-driven websites separate content from style automatically due to their inherent design.

Insert a USB flash drive into the computer and copy the downloaded .pkg file directly to the USB flash drive.
Pull the USB flash drive out of the computer and turn on the PS3. Insert the USB flash drive into the PS3.
Select the 'Install Package Files' option from the PS3 main menu. Select the .pkg file that is on the USB flash drive from the menu that comes up. The .pkg file is installed.
Press the 'O' button on the PS3 gamepad to go back to the PS3 main menu when the installation completes. The installed program is now on the PS3 main menu.

Cut a 2-foot piece of nylon beading thread. String three seed beads onto the nylon thread. Slide them down to the center of the thread.
String a seed bead onto the left end of the thread and slide it down half way on the thread. Insert the right end of the thread through the same seed bead and pull it through. Pick up both ends of the thread and pull them to make the beads move into a circle. Don't pull the ends all the way; leave the circle loose for now.
String a bead onto the left end of the thread. String a bead onto the right end of the thread. Slide the beads all the way down to the fourth strung bead or the bead at the top of the first beaded circle. Slide on a new bead onto the left end. Slide it halfway down, and then insert the right end through the right side of the bead. The bead should now have the left end hanging down from the right side and the right end hanging down from the left side. Pull the ends to make another loose circle.
Add six more circles by stringing a bead onto both ends, stringing the third bead with both ends of the thread to make a string of eight woven figure-8 circles with the beads.
Insert both the left and right ends of the thread through the bead that is facing the right and pull them through. String one bead onto each thread end, string on the third bead and insert both ends through the bead. Continue weaving the beads, using the top bead of the first row as a part of the circle as you make more circles with the beads and thread.
Close the last circle to make a ring with the woven beads. After you make the last figure 8, insert both ends of the thread through the very first bead on the strand of beaded circles. Pull the ends tight to make a ring with the beads.
Tie the ends together two times with a simple knot. Pass the left end through three adjacent beads. Pull the thread tight to make the knot slide into a bead to hide it. Trim the excess thread.
