Storage devices include devices such as memories, hard disks, floppy disks, magnetic tapes, magnetic core memories, CDs, DVDs, and MOs.
1, the use of electrical energy way to store information devices such as: various types of memory, such as RAM, ROM, etc..
2. Devices that use magnetic energy to store information such as: hard disks, floppy disks (which have been phased out), magnetic tapes, magnetic core memories, magnetic bubble memories (Magnetic bubble memories appeared in the 1970s but failed to become commercially successful when the price of hard disks dropped dramatically in the 1980s.) , and USB flash drives.
3. Devices that utilize optical means to store information such as CDs or DVDs.
4. Devices that utilize magneto-optical means to store information such as MO (Magnetic Optical Disk).
5, devices that store information using other physical objects such as paper cards, paper tapes, etc. e.g.: punched cards, punched tapes, knots, etc.
6, dedicated storage system: for data backup or disaster recovery dedicated information system, the use of high-speed networks for large data volume storage information equipment.
Stored procedures for storage devices
Stored procedures are written by the flow control and SQL statements, this process is compiled and optimized to be stored in the database server, the application program to use as long as the call can be. In ORACLE, several linked procedures can be combined to form a program package.
Stored procedures are programs written in the Transact-SQL language provided by SQL Server, which is the language provided by SQL Server for designing database applications, and is the main programmatic design interface between applications and SQL Server databases. It is the primary programmatic interface between the application and the SQL Server database. It is analogous to PL-SQL in the Oracle database system and the Informix- 4GL language in the Informix database system architecture.
