Methods, systems, and computer program products for implementing metadata management

A computer program product comprising a non-transitory computer usable medium having stored thereon a sequence of instructions which, when executed by a processor, causes the processor to perform a set of acts comprising:

• maintaining a hierarchical metadata object structure pertaining to a hierarchical object structure of a multitenant database architecture comprising a container database for a plurality of tenants, the hierarchical metadata object structure comprising an object entry structure and an object buffer structure or array;
• receiving a request from a tenant for an access to a metadata object in the hierarchical metadata object structure for one or more database objects in the container database;
• and
• in response to the request, provisioning access to at least a portion of the hierarchical metadata structure based at least in part on identifying the metadata object or a reference to the metadata object in the hierarchical metadata object structure stored in the object buffer structure or array using information in the entry object structure or array related to the request.

A system, comprising:

• a computer processor to execute a set of program code instructions;
• and
• a memory to store the set of program code instructions which, when executed by the computer processor, causes the computer processor to perform a set of acts, the set of acts comprising:
• maintaining a hierarchical metadata structure pertaining to a hierarchical object structure of a multitenant database architecture comprising a container database for a plurality of tenants, the hierarchical metadata object structure comprising an object entry structure and an object buffer structure or array;
• receiving a request from a tenant for an access to a metadata object in the hierarchical metadata object structure for one or more database objects in the container database;
• and
• in response to the request, provisioning access to at least a portion of the hierarchical metadata structure based at least in part on identifying the metadata object or a reference to the metadata object in the hierarchical metadata object structure stored in the object buffer structure or array using information in the entry object structure or array related to the request.
