Declarative entity segmentation

An apparatus for data processing, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• display, at a user interface, a first set of attributes of a plurality of attributes that are defined by a data model configured for a tenant of a multi-tenant system, the data model defining one or more entity and attribute relationships, the plurality of attributes including a one-to-many attribute that is configured to support multiple inputs per attribute and a direct attribute configured to support a single input per attribute;
• activate, based at least in part on selection of a first attribute of the first set of attributes, a second set of attributes of the plurality of attributes, the second set of attributes being activated based at least in part on each attribute of the second set of attributes being dependent on the first attribute in accordance with the data model;
• receive, via the user interface and based at least in part on activating the second set of attributes, an indication of an expression configured to identify a segment of entities of the data model;
• execute a database query, that is based at least in part on the indication of the expression, to identify the segment of entities;
• and
• transmit, to a content communication system, an indication of the segment of entities.

A non-transitory computer-readable medium storing code for data processing, the code comprising instructions executable by a processor to:

• display, at a user interface, a first set of attributes of a plurality of attributes that are defined by a data model configured for a tenant of a multi-tenant system, the data model defining one or more entity and attribute relationships, the plurality of attributes including a one-to-many attribute that is configured to support multiple inputs per attribute and a direct attribute configured to support a single input per attribute;
• activate, based at least in part on selection of a first attribute of the first set of attributes, a second set of attributes of the plurality of attributes, the second set of attributes being activated based at least in part on each attribute of the second set of attributes being dependent on the first attribute in accordance with the data model;
• receive, via the user interface and based at least in part on activating the second set of attributes, an indication of an expression configured to identify a segment of entities of the data model;
• execute a database query, that is based at least in part on the indication of the expression, to identify the segment of entities;
• and
• transmit, to a content communication system, an indication of the segment of entities.
