detect headers as column names and assign appropriate data types like number or varchar2
based on the content. This helps users quickly prepare their data for analysis without
manual intervention, reducing setup time and minimizing the chance of errors.
Autonomous Database supports a
federated metadata catalog, enabling users to unify metadata from different sources into a
single view, providing a unified interface for metadata management.
This approach simplifies metadata management across various environments by
connecting data sources across multiple clouds and platforms. Whether using
catalog-based metadata or defining it manually, all information is available in a
unified catalog for easy browsing. For example, an organization can use this federated
view to manage data assets from both AWS and Oracle Cloud, ensuring consistent
governance and discoverability across platforms.
After users finish their analysis, they often need to share their results
with others. Oracle Autonomous Database makes
sharing easy by offering several ways to collaborate, providing unique advantages over other
databases, such as integrated security features, open protocols, and seamless cloud
connectivity.
These options are made to be flexible and secure, so they fit different
collaboration needs:
Delta Sharing Protocol: This lets you share data outside of
Oracle using an open protocol called Delta Sharing. It supports secure data
sharing with external partners, without needing complex integration, making it
ideal for cross-cloud and cross-platform analytics. This way, data can be used
smoothly in different analytics tools that are not part of Oracle. See Share Data Versions Using Object Storage, for more
information.
Cloud Links: You can share data between different Autonomous Database instances using
secure cloud links. For example, Cloud Links are particularly effective for
connecting different databases. This ensures consistent data availability and
reduces latency for applications needing quick and reliable access to data
across multiple databases, without the need to copy or duplicate. It keeps
collaboration smooth for teams that are spread out and need to work together.
