AAI data views can be used by homing logic during real-time service delivery, root cause analysis of problems, impact analysis, capacity management, software license management and many other functions.
AAI is metadata driven, allowing new inventory item types to be added dynamically and quickly via SDC catalog definitions, reducing the need for lengthy development cycles.
An API is available.

Functionality
AAI includes the following specific functions:
- Inventory and Topology Management
- Administration
- and Reporting and Notification.
Inventory and Topology Management
AAI federates inventory using a central registry to create the a global view of D2 inventory and network topology. A&AI receives updates from the various inventory masters distributed throughout the D2 OpenECOMP infrastructure, and persists just enough to maintain the global view. As transactions occur within D2, AAI persists asset attributes and relationships into the federated view based on configurable metadata definitions for each activity that determine what is relevant to the AAI inventory. AAI provides standard APIs to enable queries from various clients regarding inventory and topology. Queries can be supported for a specific asset or a collection of assets. The A&AI global view of relationships is necessary for forming aggregate views of detailed inventory across the distributed master data sources within D2.
Administration
AAI also performs a number of administrative functions. Given the model driven basis of ECOMP, metadata Metadata models for the various catalog items assets are stored, updated, applied and versioned dynamically as needed without taking the requiring a system down shutdown for maintenance. Given the distributed nature of AAI as well as the relationships with other ECOMP OpenECOMP components, audits are periodically run to assure that AAI is in sync with the inventory masters such as controllers and MSO. Adapters allow A&AI to interoperate with non-D2 systems as well as 3rd party cloud providers via evolving cloud standards.
Reporting and Notification
Consistent with other ECOMP OpenECOMP applications, A&AI produces canned and ad-hoc reports, integrates with the ECOMP OpenECOMP dashboards, publishes notifications that other ECOMP OpenECOMP components can subscribe to, and performs logging consistent with configurable framework logging that is consistent with configurable framework constraints.
