Line 27:
== Language-level abstraction ==
An example of a database abstraction layer on the language level would be [[ODBC]]. ODBC is a platform-independent implementation of a database abstraction layer. The user installs specific driver-software, through which ODBC can communicate with a database or set of databases. The user then has the ability to have programs communicate with ODBC, which then relays the results back and forth between the user programs and the database. The downside of this abstraction level is the increased overhead to transform statements into constructs understood by the target database.
Alternatively, there are thin wrappers, often described as ''lightweight'' abstraction layers, such as OpenDBX<ref>{{cite web |url=https://www.linuxnetworks.de/doc/index.php?title=OpenDBX |title=OpenDBX |author==<!--Not stated--> |date=24 June 2012 |website=linuxnetworks.de |access-date=26 July 2018}}</ref><ref>{{cite web |url=https://en.wikipedia.org/wiki/Wikipedia:Articles_for_deletion/OpenDBX |dead-url=yes |title=OpenDBX | archive-url=https://web.archive.org/web/20060913000000/http://en.wikipedia.org:80/wiki/OpenDBX |archive-date=13 September 2006}}</ref> and libzdb.<ref>{{cite web |url=http://www.tildeslash.com/libzdb/ |title=Libzdb |author==<!--Not stated--> |access-date=26 July 2018 |year=2018 |website=tildeslash.com}}</ref> Finally, large projects may develop their own libraries, such as, for example, libgda<ref>{{cite web |url=http://www.gnome-db.org/ |title=GNOME-DB |author==<!--Not stated--> |access-date=26 July 2018 |date=12 June 2015 |quote=Libgda library [...] is mainly a database and data abstraction layer, and includes a GTK+ based UI extension, and some graphical tools.}}</ref> for [[GNOME]].
