A DATABASE IS A WEB DEVELOPER’S DAILY TOOL, and he or she should know SQL
at least as well as PHP. Most data models of Web applications involve a relational
database.While novice users may try to avoid the perceived overhead of SQL and a
relational database management system (RDBMS), the advanced developer appreciates
the features it provides. Anything nontrivial—for example, concurrent accesses,
searching and sorting, or allowing relations between different datasets—quickly
becomes a pain when using storage methods like flat files or arrays. Databases are built
for efficient organization and retrieval of data, and in most cases there’s no need to
mimic this feature set in pseudo database systems.
