Hello @pmscorca .
Your initial ask is very broad. Could you perhaps add some more details, like what type of things you are looking to find out?
It is to my understanding that datamart implies columnstore, and Synapse Dedicated Pools are columnstores. Given you selected Azure Synapse Analytics in the tagging of this question, I have tailored information with regards to Synapse compatibility.
You may also be interested in looking at Azure Purview. While Azure Purview is mostly about data governance, it also does data discovery. (Correct me if I am wrong about discovery being similar to exploration.)
Azure Purview automates data discovery by providing data scanning and classification as a service for assets across your data estate. Metadata and descriptions of discovered data assets are integrated into a holistic map of your data estate. Atop this map, there are purpose-built apps that create environments for data discovery, access management, and insights about your data landscape.
Azure Purview can work with many Azure services, and has integration with Azure Synapse. Azure Synapse also has integration available with Azure Purview.
Azure Purview also can connect to SAP ECC , SAP HANA , and SAP S/4HANA .
Microsoft PowerBI is cited as data exploration software by Wikipedia.
Azure Synapse has several integrations with PowerBI.
