Structured Query Language (SQL) is a programing language designed for managing data held in relational databases. Since 1986 SQL has been the database standard in the American National Standards Institute (ANSI). SQL databases are more secure because their structure is more transparent and the development community works together to promote security. MySQL is one of the most widely available SQL database implementations.
Benefits of SQL include:
Lightweight Data Access Protocol (LDAP)
Read vs. read/write access
Licensing agreement control
Portability – ArcGIS, billing data, etc.
Automated Programming Interface (API)
Tablet- or PC-based access
Acceptance of in-field data collection by one or multiple users concurrently
System admin rights for custom reporting and user access modifications
Decouple method of access from the database interface.
Access, timeframes / expiration, usage reports
Single sign-on for multiple systems (database, payroll, server access, etc.)
