  attacks                 • Diagnostic tools for
• Sophisticated             developers
  architecture            • Easily scalable
Architecture
Basic usage: SQL queries
SQL
PHP
Neevo
Connecting to the database
PHP – PostgreSQL & MySQL


               Login credentials

Conditional SQL queries
PHP
      Conditional part
      of the query
Neevo

        Conditional part
        of the query
Source code coverage
                       191 unit tests
                  11 integration tests
Scalability – custom DB driver
Diagnostic tools

• Observer pattern: IObserver, IObservable
  and their implementations

• Info about queries:
  – Result::explain() – EXPLAIN query
  – Statement::getTime() – duration of query
