A database works by storing data in logical structures called tables. These tables are then organized into larger groupings called schemas.Continue Reading
A database is used to store information, and by using the various tables and schemas, data can be stored and moved easily. Databases are useful as they allow for simply recall of data while using fewer resources than other data storage methods.
Many times database administrators index or store a column of information from the table for faster response time. This indexing is similar to viewing what files are in a folder on a computer. The first time this occurs, it can take a fair amount of time as the operating system is viewing all the files that are in the folder. After this first attempt, the system gets faster, since it already knows what to expect. Instead of searching again for the information, it saves data in an index file. When changes are made to the folder, or in the database, the changes are marked in the indexes, making it faster for data recall.Learn more about Software
