Tableau-file-types

Tableau-ファイルの種類

Tableauでのデータ分析の結果は、保存および配布するためにさまざまな形式で保存できます。 さまざまな形式は異なるファイルタイプと呼ばれ、異なる拡張子で識別されます。 それらのフォーマットは、それらがどのように作成され、どのような目的で使用されるかに依存します。 これらはすべてXMLファイルとして保存され、開いて編集することができます。

次の表に、各ファイルタイプとその使用法の説明を示します。

File Type	File Extension	Purpose
Tableau Workbook	.twb	It contains information on each sheet and dashboard that is present in a workbook. It has the details of the fields, which are used in each view and the formula applied to the aggregation of the measures. It also has the formatting and styles applied. It contains the data source connection information and any metadata information created for that connection.
Tableau Packaged Workbook	.twbx	This file format contains the details of a workbook as well as the local data that is used in the analysis. Its purpose is to share with other Tableau desktop or Tableau reader users, assuming it does not need data from the server.
Tableau Data Source	.tds	The details of the connection used to create the tableau report are stored in this file. In the connection details, it stores the source type (excel/relational/sap, etc.) as well as the data types of the columns.
Tableau Packaged Data source	.tdsx	This file is similar to the .tds file with the addition of data along with the connection details.
Tableau Data Extract	.tde	This file contains the data used in a .twb file in a highly compressed columnar data format. This helps in storage optimization. It also saves the aggregated calculations that are applied in the analysis. This file should be refreshed to get the updated data from the source.
Tableau Bookmark	.tbm	These files contain a single worksheet that is shared easily to be pasted into other workbooks.
Tableau Preferences	.tps	This file stores the color preference used across all the workbooks. It is mainly used for consistent look and feel across the users.
