Storage TypesFor the purpose of this web site, data storage is the saving of any data that may be made and stored electronically. Some examples of data storage are the following: an e-mail that is typed on your computer and saved to your Google account, a contract that is saved to a thumb drive or USB, or pictures that are saved to the hard drive of your computer.
Data storage can refer to anything with information recorded on it, but when dealing with computers and similar devices, data storage refers to the primary and secondary storage of computer data.
Computer memory refers to the data that a CPU can directly access. Components that store memory are considered primary storage devices. Secondary data storage devices are everything else, such as hard drives, CD-ROMs, and flash memory. Secondary data storage can be broken up into three categories: on-site, removable, and off-site. On-site refers to any devices that is never intended to leave the computer, like a hard drive. Removable memory refers to devices that are designed to be removed from the computer easily, like a CD-ROM or a flash drive. Off-site storage refers to the storage of data away from the computer, but can be easily accessed.
There are many different factors to consider when looking to expand your computer data storage capacity by means of online storage or external hard drive storage. These include storage capacity, cost, ease of use, convenience, added features, security concerns, cost efficiency, access to data, data safety, and maintenance.
Online storage is cheaper, but external hard drive storage offers more storage capacity. You can more easily store files with online storage, but larger files can take a long period of time to load. Most importantly, you need an internet connection to access online files. Online storage also has low maintenance, offers safety from physical damage, cost efficiency, and access to data if you have an internet connection.
On the other hand, you can always access an external hard drive, they are faster, but files are not as easy to share and they are not as convenient since they need to be attached to the computer to be of use.
Both methods of storage have their own security concerns and neither method has an advantage in this respect.
Data mining is the process of analyzing data from different perspectives and summarizing it into useful information. Data are any facts, numbers, or text that can be process by a computer. The patterns, associations, or relationships among all collected data can provide information. Information can be converted into knowledge about historical patterns and future trends. To maximize user access and analysis, there needs to be a centralization of data in a data warehouse.
Data mining provides the link between transactions and analytical systems. Data mining software analyzes relationships and patterns in stored transaction data based on queries. The two critical technological drivers of data mining are size of the database and query complexity.
