Kubuntu no longer ships with a default database application, however you have options in which to choose from.
OpenOffice.org Base je databázová aplikace vytvořena stejnou skupinou, která vytvořila kancelářský balík OpenOffice.org. OpenOffice.org Base se nachází ve zdroji Main. Podívejte se do dokumentace Přidávání aplikací pro pomoc s instalací.
Kexi is also a choice for a database application. Kexi is part of the KDE KOffice suite and tends to integrate better within KDE. Kexi is in the Main repository. Please refer to the Adding Applications documentation for help on installation.
It is recommended you try both applications in order to see which one works best in your situation.
