Before you can create an online database, you’ll need to set up a database server account at an Internet service provider. The provider owns and operates the server equipment and provides the software at their facility; you pay for the service and have access to the database. Database software offerings include Microsoft SQL Server, Oracle, MySQL, MongoDB and others; these platforms feature fast response times for busy websites. For websites that have relatively low amounts of activity, you can opt to create a Microsoft Access or FileMaker Pro database and upload it to the service provider.
Client Tools
In addition to the online account, you’ll need software tools on your PC to manage the database from your desktop. The database vendor provides management software that lets you create tables, indexes and other database structures; generally, the software is proprietary and works only with the vendor’s database. For example, Microsoft’s Management Studio desktop software lets you administer SQL Server databases.
Security
Online databases have an administrator’s user ID and password that grants complete access to the database. For best security, create additional user ID and passwords that access only those data items that are absolutely necessary for a specific purpose; otherwise, a hacker may gain control of your database and steal confidential information.
Loading Data
Once created, a database is an empty structure that may need useful data to function correctly. For example, an online toy store needs inventory records describing each toy for sale, including a model number, description and price. If you already have this information in another format -- a Microsoft Excel spreadsheet, for example -- you can use the client tool software to copy the Excel data into the database. If you do not have this data in a computerized form, you will need to key it in by hand.
Program Connection
Web programs use information in the online database to make the website work; the programs read the data and send the user Web pages based on the database content. Each program incorporates a piece of data called a connection string; the string specifies the database name, the server’s Internet Protocol address, a login ID and password, and other information. The program’s housekeeping section uses the string to open the database; other parts of the program search for data, change existing records or add new ones. To help keep your database secure, use restricted-access user IDs and passwords in your programs, not the administrator’s ID.

Navigate to the website on which you want to upload your video file that is over 200 MB in size. YouTube and Flickr both allow videos with file sizes of 200 MB, but you need to create a new account or use an existing account. To upload a video file of 200 MB to Flickr you need to purchase a Pro account; YouTube allows file sizes up to 2 GB. You can also visit free file hosting sites, such as YourFileLink to upload a video.
Click the link or button that allows you to upload the video. A dialog box will open asking you to select the video on your computer that you want to upload.
Choose the video that you want to upload in the dialog box. Once you have chosen the video, the upload process will start, and will complete in some time depending on your Internet speed and availability of free servers on the website on which you are uploading the video.
