The Tabular Data Widget (TDW) is a GWT component for tabular data visualization and manipulation.
The TDW components extends the GXT Live grid component enhancing it with:
- dynamic data model
- custom data source definition
- common tabular data operations
- graph visualization
Tabular Data Widget Architecture
The TDW is composed by several GWT components, in the figure grouped as TDW widget, and two HTTP servlet, one for the GWT RPC mechanism and another as JSON provider, both represented as TDW servlet. The TDW servlet communicates with the available datasources in order to retrieve the necessary information for the tabular data visualization.
Tabular Data Model
The TDW visualizes tables. A table is defined though a table definition. The table definition describes some essential information about the table (id, name, etc) and it keeps a description of each column belonging to the table. The column definition keeps some information about the described column like id, label the type of data and so on.
