Description

Interface Summary

DatabaseStorage
DataTableModel.DataTableModelGUIListener
FilterChangedListener
ForwardOnlyData	For those who want to implement a new ForwardOnlyData (probably in a new DataTableModel): Note that this automatically upgrades the table whenever something is accessed that doesn't currently exist, if a TableFormat has been set for the table.
TableFormat	A table in the database that can be created upon demand, and can be upgraded on demand.
TableFormat.ColumnFormat
TableFormat.ColumnFormatKnowHowToCreate	A column that is non-standard or expected to be needed in an upgrade, with special upgrade needs (more than just creating the column).
TableFormat.TableFormatAndDoMore
TableStorage	Load tables from a database through this generic interface.
TableStorage.SearchingForConnectionListener	Recieves notifications of whether the TableStorage is currently unavailable and waiting for a new connection.
TableStorage.TableListListener	Recieves notifications whenever the list of tables changes -- i.e. on any of these events: - a table is created - a table is deleted - a table is renamed

Class Summary

DatabaseConstants
DatabaseConstants.AuxillaryOptions	See QuestionsAuxillaryOptionTypes.xls (in this folder) for a spreadsheet of most of these, with details about which columns from the database they should get pulled from.
DatabaseConstants.Choices
DatabaseConstants.Questions
DatabaseConstants.Variables
DatabaseStorage.UserDatabase	Info about a connection to the database that a user has.
DatabaseStorageFactory
DatabaseStorageFactory.ConnectionType
DataTableModel	Accesses database data in a generic fashion.
DataTableModelSingularInfo<DTM extends DataTableModel>	The information about a data table that is independent of its views.
Filter<T>	Show only rows matching certain criteria.
FilterStorage
OrderBy	A direction to sort a column.
TableFormat.ColumnFormatRenamed	This assumes that neither the old nor new columns are primary keys, and that the old and new columns are the same type.
TableFormat.ColumnFormatStub
TableFormat.TableFormatStub
TableFormat.TableFormatStubAndDoMoreAddRow	Adds a default row of data automatically when the table is created.
TableStorageFactory
TableStorageStub<DTM extends DataTableModel>
TableVersionStorage	Check what version of the table is in the database before upgrading to a new one.
VectorDataSet<T extends HasBeenModified>	For storing a Vector of data that needs to be loaded and re-saved.
WebappConfiguration

Exception Summary

FailedRequest	Data could not be retrieved, either beause the table is too old, a column does not exist, or because a SQL error occurred.
FailedRequest.AlreadyClosedError
FailedRequest.BadColumnNameException
FailedRequest.DatabaseFailure
FailedRequest.TableVersionNewerThanProgram	The table is newer than the code requesting it.
WebappConfiguration.WebappError
WebappConfiguration.WebappNeedsToBeRestartedError
WebappConfiguration.WebappNotConfiguredError

Package cmu.survey.data Description

Data components that are shared between multiple parts of the program, or that are fairly generic. For example, TableStorage is used in:

• Survey Manager in DatabaseObjectStorage
• Survey Editor in cmu.survey.data
  
• Database Editor in DatabaseEditor
• and many more in those groups and elsewhere.
  

Specifically, this package is made for generic data components that can be used in many places in different programs, that are specifically designed to be program-independent.
