Filters are the simpler and straightforward feature in Tableau. It applies to dimensions or measures directly. For example, to only show Gujarat or Karnataka in a State dimension, we can apply the filter on that. In Tableau, there are multiple UI options available for filters like radio buttons, drop-down lists, checkboxes, sliders, and more. Filters on sheets are also available in Tableau. Parameters are like variables.
They are complex and more powerful. Like a variable, a parameter can be used in calculations. So, that means, it only allows a single value. For example, we can create a parameter for interest rate and period, and then we can use these parameters to calculate interest and principal payments. Filters are used to provide the correct information to viewers after removing unnecessary data. There are various types of filters available in Tableau.
Extract Filters — Extract filters are used to apply filters on extracted data from the data source. For this filter, data is extracted from the data source and placed into the Tableau data repository. Datasource Filters — Datasource filters are the same as extract filters. They also work on the extracted dataset.
But, the only difference is it works with both live and extract connections. Context Filters — Context Filters are applied on the data rows before any other filters. Dimension Filters — Dimension filters are used to apply filters on dimensions in worksheets. Dimension filters are applied through the top or bottom conditions, formula, and wildcard match.
Measure Filters — Measure filters are applied to the values present in the measures. The layout will be adjusted according to dashboard size. In the floating layout, items can be placed on some other layers. Floating items can have fixed positions and sizes.
Slowly ever-changing dimension : The value of the dimension changes over an amount of time for slowly ever-changing dimensions. Chop-chop ever -changing Dimension: Value in the dimension is rapidly changing for chop-chop ever-changing dimensions. Junk Dimension: Junk values or unrelated dimensions are termed as Junk Dimension. Conformed Dimension: If any dimension is provided by various business areas, then such a dimension is termed as Conformed Dimension.
Degenerated Dimension: Degenerated dimensions have primary keys only without any matter of info. Role enjoying Dimension: If one dimension is employed in multiple roles, then they are termed as Role enjoying Dimensions. Inferred Dimension: Empty dimensions are called inferred dimensions.
They are usually used in ETL. Example — Customer email which he may not enter while submitting any form will be filled as null. It is similar to SQL language. Example — individual salary transactions for each employee. Discrete data roles consist of values that are separate and distinct. Discrete data roles can take individual values within a range. For Example — cancer patients in the hospital, no.
Discrete values are displayed as blue icons in the data window and blue pills on shelves. Discrete fields can be sorted. Continuous data roles consist of any value within the finite or infinite intervals. For Example — age, unit price, order quantity. Continuous values displayed as green icons in the data window and green pills on shelves. Continuous fields cannot be sorted. Tableau does not have dependencies. It does not support in-memory, multi-thread, and multi-core computing.
It supports memory when used advanced technologies. It has a predefined view of data. It uses predictive analysis for various business operations. We should need a good knowledge of BI and skills.

They only allow a single value. Only site admin can change the ownership of those workbooks. Extract connection is better than live connection because extract connection can be used from anywhere, anytime without connecting to the database.
We can construct our own visualizations on it irrespective of the database connection. Cascading filters means filter2 values are dependent on filter1 values. Tableau cannot plot null values on-axis.
So, it will display an indicator at the lower right corner of the view. Once you click on that indicator, you have options to handle null values. Below are the options available to handle null values. Yes, Tableau Public can only allow 10 million rows to users for data visualization. We can download views or workbooks from the server. But, data formats available to us depend on the permissions granted by site administrators or content owners. Extract files can be used without any connections and you can build your own visualization without connecting to the database.
Yes, we can place an excel file in a shared location and we can use it to develop a report, but for better performance, we need to extract the file. Yes, we can do testing in Tableau by using tools and the easiest way is using the desktop application. We need to check it before we publish it on the Tableau server. Tableau, currently not supporting the multi-valued parameters. As Tableau parameters are not dynamic, we cannot filter the list of values at runtime.

We cannot access those links. Yes, Parameters have their own drop-down list, which enables the users to view the data entries which are available in the parameter during the creation. When we are publishing the reports to Tableau Server, there we will find an option to schedule the report, just select the time when you want to refresh the data.
Whenever we set a context filter, Tableau generates a temp table that needs to refresh each and every time the view is triggered. So, if the context filter will be changed, the database needs to recompute and rewrite the temp table, which in turn slows down the performance. The published data source has connection information in it. It is independent of any workbook and can be accessed by multiple workbooks. Multiple measures can share a single axis so that all the marks will be shown in a single pane.
