The driver acquires and refreshes Azure AD bearer tokens by using either the identity of the end user or a configured Service Principal. A major integration challenge faced by companies when on boarding and managing their data centers around managing data dictionaries, data mappings, semantics and business definitions of their data. Each service (Dynamics 365, Dynamics 365 Finance, and Power BI) creates and owns its own file system. With the evolution of the Common Data Model metadata system, the model brings the same structural consistency and semantic meaning to the data stored in Microsoft Azure Data Lake Storage Gen2 with hierarchical namespaces and folders that contain schematized data in standard Common Data Model format. Azure Data Lake is fully supported by Azure Active Directory for access administration Role Based Access Control (RBAC) can be managed through Azure Active Directory (AAD). Delta Lake on Azure Databricks allows you to configure Delta Lake based on your workload patterns and has optimized layouts and indexes for fast interactive queries. Each data producer stores its data in isolation from other data producers. This allows multiple data producers to easily share the same data lake without compromising security. Data lakes store data of any type in its raw form, much as a real lake provides a habitat where all types of creatures can live together.A data lake is an Thus, we provide in this paper a comprehensive state of the art of the different approaches to data lake design.
