[DataSetObservable](/reference/kotlin/android/database/DataSetObservable) | A specialization of [Observable](/reference/kotlin/android/database/Observable) for [DataSetObserver](/reference/kotlin/android/database/DataSetObserver) that provides methods for sending notifications to a list of [DataSetObserver](/reference/kotlin/android/database/DataSetObserver) objects. |\n| [DataSetObserver](/reference/kotlin/android/database/DataSetObserver) | Receives call backs when a data set has been changed, or made invalid. |\n| [DefaultDatabaseErrorHandler](/reference/kotlin/android/database/DefaultDatabaseErrorHandler) | Default class used to define the action to take when database corruption is reported by sqlite. |\n| [MatrixCursor](/reference/kotlin/android/database/MatrixCursor) | A mutable cursor implementation backed by an array of `Object`s. |\n| [MergeCursor](/reference/kotlin/android/database/MergeCursor) | A convenience class that lets you present an array of Cursors as a single linear Cursor. |\n| [Observable](/reference/kotlin/android/database/Observable) | Provides methods for registering or unregistering arbitrary observers in an [ArrayList](../../java/util/ArrayList.html#). |\n\nExceptions\n----------\n\n|-------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------|\n| [CursorIndexOutOfBoundsException](/reference/kotlin/android/database/CursorIndexOutOfBoundsException) | An exception indicating that a cursor is out of bounds. |\n| [CursorWindowAllocationException](/reference/kotlin/android/database/CursorWindowAllocationException) | This exception is thrown when a CursorWindow couldn't be allocated, most probably due to memory not being available. |\n| [SQLException](/reference/kotlin/android/database/SQLException) | An exception that indicates there was an error with SQL parsing or execution. |\n| [StaleDataException](/reference/kotlin/android/database/StaleDataException) | This exception is thrown when a Cursor contains stale data and must be requeried before being used again. |"]]
