Interview Questions Table Beginner
What is Tableau?
Tableau is a business intelligence software.
This allows anyone to connect with each data.
Visualize and create a dashboard that can be shared interactively.
What are the latest Tableau products and what is the latest version of Tableaue?
This is an independent business analytic and data visualization that can be used by anyone. This translates image data into an optimized query. With desktop tableau, you can directly connect to data from your data warehouse for the latest data analysis. You can also do a query without writing one line of code. Import all your data to the Tableau data machine from various sources & integrated it at all by combining multiple displays in interactive dashboards.
(ii) Tableau Server:
This is more of a tableau software level company. You can publish the dashboard with desktop tableau and share it throughout the organization with a web-based tablbo server. This utilizes fast databases through direct connections.
(iii) Tableau Online:
This is the host version of Tableau Server which helps make business intelligence faster and easier than before. You can publish the Tableau dashboard with desktop tableau and share it with colleagues.
(iv) Tableaue reader:
This is a free desktop application that allows you to open and see visualization built on the desktop tableau. You can filter, browse data but you cannot edit or do any type of interaction.
(v) Public Tableau:
This is a free tabl-software that you can use to make visualization with but you need to save your workbook or worksheet on the Tableau server that can be seen by anyone.
What size and dimensions?
Actions are numerical metrics or measurable amounts of data, which can be analyzed with table dimensions. Actions are stored in a table containing foreign keys that refer uniquely to the related dimensions table. Tables support data storage at the atomic level and thus, allow more numbers of records entered at one time. For example, sales tables can have a product key, customer key, promotional keys, goods sold, refer to certain events.
Dimensions are descriptive attribute values for various dimensions of each attribute, define various characteristics. Table dimensions, have product key references from tables, can consist of product names, type of product, size, color, description, etc.
What is the difference between the extension .twb and .twbx?
A .twb is an XML document that contains all the options and layout that you created in your Tableau workbook. It does not contain any data.
A .twbx is a ‘zip’ archive that contains .twb and any external file such as extracts and background images.
What are the different connections that you can make with your dataset?
We can connect directly to our data set or extract data to Tableau.
Direct: Connecting directly to the data set utilizing processing and computing storage. The new query will go to the database and will be reflected as new or updated in the data.
Extract: Extract will make a static snapshot of data that will be used by the Tableau data machine. Data snapshots can be refreshed on recurring schedules as additional data or gradually. One way to set this schedule is through the Tableau server.
What is that?
The set is a special field that determines the data subset based on several conditions. A set can be based on calculated conditions, for example, a set can contain customers with sales through a certain threshold. Stick set updates as a change in your data. Or, a set can be based on certain data points in your display.
What is a group?
The group is a combination of the dimensions of members who make higher-level categories. For example, if you work with a display that shows the average test score with the main, you might want to group certain majors to create the main category.
What is a Tableau data server?
Tableau server plays a middle man between tables and data users. Tableau Data Server allows you to upload and share data extract, maintain database connections, and reuse calculations and field metadata. This means that every change you make to the data set, the calculated field, parameters, aliases, or definitions, can be stored and shared with others, allowing safely managed datasets, managed centrally, and standardized. In addition, you can use your server resources to run queries on extracts without having to first transfer them to your local machine.
