Additional namespace information: Overview, Class Diagram

The Data namespace contains classes to access data stored on disk. It provides the capability for you to find out what is stored inside a geodatabase or directory and to be able to access and query that data.

Classes

	Class	Description
	ArcSDEConnectionProperties	Represents the information required to make a spatial database connection to an ArcSDE geodatabase.
	CodedValueDomain	Represents a geodatabase coded value domain which consists of value/name pairs and acts like a database lookup table (e.g. the column values are stored as integers but looked-up as string descriptions).
	Column	Represents a set of values in a Table that have the same data type.
	ColumnCollection	Represents a collection containing all the columns in the Table.
	DataDirectory	Represents a directory on disk and specifically one which stores shapefiles, dBase files or any supported raster files.
	DataSourceProperties	Represents the connection information to one of the following data types: geodatabase feature class, geodatabase raster, shapefile or any of the supported file-based raster formats. The information stored by instances of this class are used by FeatureLayer and RasterLayer objects to make a connection to the specified data source.
	Domain	Represents a geodatabase domain of which there two types: CodedValueDomain or RangeDomain.
	DomainCollection	Represents all the domains defined in a geodatabase.
	Filter	Represents the criteria used to perform either an attribute or spatial search on a Table.
	Geodatabase	Represents an ESRI geodatabase which is a container for storing geographic datasets of various types.
	GeodatabaseFolder	Represents a geodatabase feature dataset.
	Index	Represents a physical index on a column or columns in a Table which is stored on disk.
	IndexCollection	Represents a collection of Index objects associated with a Table, each of which represents a physical index defined on disk.
	RangeDomain	Represents a geodatabase range domain which ensures that the values in a Column must be between the minimum and maximum specified values.
	Raster	Represents a raster dataset consisting of a rectangular grid of cells arranged into rows and columns, and composed of single or multiple bands. In the context of a geodatabase a Raster object represents a raster whereas when accessing data in a directory it represents any of the supported, file-based, raster formats.
	Row	Represents a single record of data in the Table.
	RowCollection	Represents a number of records from the Table.
	RowValueCollection	Represents the values stored in an individual Row in the Table, with one value for each Column.
	ServiceConnectionProperties	Represents the connection information to one of the following types of service: ArcGIS Server (2D, 3D and image services), IMS, WMS and Bing (formerly Virtual Earth). The information stored by instances of this class are used by ServerLayer objects to make a connection to the specified service.
	Subtypes	Represents a geodatabase subtypes entity which allows a table or feature class to be categorized if they share the same attributes.
	Table	Represents both tabular data and spatial vector data. In the context of a geodatabase, a Table object represents either a table or feature class entity whereas when accessing data in a directory it represents either a dBase table or a shapefile.
	TableBindingAdapter	Represents a .NET bindable data source. This allows a Table to be bound to any .NET Control supporting data binding.
	TableRelationship	Represents either a permanent geodatabase relationship class or an in-memory relationship between two tables.
