Table and Row Organization

POCO DataSet organizes data through a clear two-level structure: tables and rows. Each DataTable defines its schema through ColumnMetadata and stores row data in DataRow objects. This separation ensures predictable data flow, clean layering, and support for dynamic UI generation.

Key Characteristics

• Each DataSet contains multiple DataTables identified by name.
• Each DataTable contains ColumnMetadata defining schema.
• Each DataRow contains values matching the table's column definitions.
• Schema and data are stored separately but linked through the DataTable.
• Rows do not carry schema; they reference DataTable metadata for structure.

This arrangement enables flexible data manipulation and makes POCO DataSet suitable for data-driven architectures and dynamic user interfaces.

• Column Oriented Representation
• Row Oriented Access
• Performance vs Readability
• Differences from Classic DataSet
• Storage Layout Diagrams
