We should implement some practices that will ensure the enterprise-wide implementation
- Data sources should be created only once. All the common transformations and calculations should be present in this data source.
- The data source should be shared with other users creating the dashboards. Data Source/s can be shared by publishing them on the server or by creating a TDS file.
- The look and feel of the dashboard should be the same. Color scheme, fonts, etc. should be decided and implemented in all the dashboards.
- Create a dashboard review board that will review all the dashboards before moving to production. This will ensure that standards are maintained.
Tableau Server licensing comes in two modes – User-based or core-based.
User-based licensing restricts how many users can work on your installation of Tableau Server. Tableau Server can be installed on a single machine or multiple machines in a cluster.
Core-based licensing provides a license on the number of cores on a single machine installation or multi-node installation. It does not restrict the number of users in the system.
Tableau automatically aggregates measures on the view canvas. Default aggregation in Sum.
When you drop a measure field, the aggregation applied is Sum.
This aggregation can be changed to Average or any other type. When an “aggregated measure” is used in a calculation and then the calculation is placed on the view canvas, it shows Agg in front of the calculated column. It means that aggregation is built within the calculation. This aggregation cannot be changed.
Tableau Data Extract (TDE) file is an extract of data and it depends on the size of the source data. As it is a compressed file, it will be smaller than the original size of the source data.
