Relational database management systems address all these issues:
Probably the main reason for using an RDBMS is that all (or at least most) of the functionality that you want in a data storage system has already been implemented.
- RDBMSs can provide much faster access to data than flat files.And MySQL, the database system we use in this book, has some of the fastest benchmarks of any RDBMS.
- RDBMSs can be easily queried to extract sets of data that fit certain criteria.
- RDBMSs have built-in mechanisms for dealing with concurrent access so that you, as a programmer, don’t have to worry about it.
- RDBMSs provide random access to your data.
- RDBMSs have built-in privilege systems. MySQL has particular strengths in this area.
