Q12. What is meant by Data Sources in Domo?
When data from an external source is loaded into Domo Advanced Server, it is stored internally in a data funnel. A data funnel is multiple representations of data, regardless of the data's actual source. Data can be modified, altered, processed, transformed, and performed in several ways once it is loaded into a data funnel before being digested into a visual representation (gauge, map, etc.) or displayed in another format, such as a table.
- Data from a wide range of sources can be accessed by Domo Advanced Server. Java JDBC drivers are used to connect to databases. ODBC is also accessible in Windows systems. Microsoft SQLServer®, PostgreSQL,
- DB2, MySQL, and Oracle are just a few of the major databases supported. However, Domo Advanced should be able to access any SQL database that has a JDBC driver via database-specific Sql statements.
- Domo Advanced Server can read information from various web pages in CSV, HTML tables, tab-delimited text files, and Microsoft Excel files.
