php-db binary package in Ubuntu Xenial amd64

 DB is a database abstraction layer providing:
  * an OO-style query API
  * portability features that make programs written for one DBMS work
    with other DBMS's
  * a DSN (data source name) format for specifying database servers
  * prepare/execute (bind) emulation for databases that don't support it
    natively
  * a result object for each query response
  * portable error codes
  * sequence emulation
  * sequential and non-sequential row fetching as well as bulk fetching
  * formats fetched rows as associative arrays, ordered arrays or objects
  * row limit support
  * transactions support
  * table information interface
  * DocBook and phpDocumentor API documentation
 .
 DB layers itself on top of PHP's existing database extensions.
 .
 Drivers for the following extensions pass the complete test suite and
 provide interchangeability when all of the database's portability
 options are enabled:
  fbsql, ibase, informix, msql, mssql,
  mysql, mysqli, oci8, odbc, pgsql,
  sqlite and sybase.
 .
 There is also a driver for the dbase extension, but it can't be used
 interchangeably because dbase doesn't support many standard DBMS
 features.
