Systems and methods for dynamically intercepting and adjusting persistence behaviors via runtime configuration

A method for dynamic runtime modification of an object-relational mapping behavior associated with a relational persistence layer, comprising:

• accessing data stored in a relational persistence layer;
• mapping data from the relational persistence layer to an object-oriented domain model using an object-relational mapper (ORM), wherein the ORM comprises a plurality of field mappers each configured with an original mapping strategy to map an entity field from the relational persistence layer to the object-oriented domain model;
• configuring a selected field mapper of the ORM with a dynamic adjustment strategy, wherein the dynamic adjustment strategy is configured to allow the selected field mapper to be injected with a temporary or conditional mapping behavior during runtime;
• wherein the injected temporary or conditional mapping behavior comprises an OnlyAdjustIfColumnDoesNotExist mapping behavior that causes the selected field mapper to persist data in a currently non-existent entity field of the relational persistence layer as soon as the non-existent entity field is made available;
• injecting into the selected field mapper during runtime a temporary or conditional mapping behavior that is different from the original mapping strategy of the selected field mapper;
• and
• mapping data via the selected field mapper as per the temporary or conditional mapping behavior defined by the dynamic adjustment strategy.

A non-transitory computer-readable medium having instructions that, when executed by a processor, cause the processor to perform operations to cause a dynamic runtime modification of an database mapping behavior associated with a persistence layer, the operations comprising:

• accessing data stored in a persistence layer using a first type of data organizational schema;
• mapping data from the persistence layer to a domain model using a second type of data organizational schema via an organizational schema mapper (OSM), wherein the OSM comprises a plurality of mappers each configured with an original mapping strategy to map a field from the persistence layer to the domain model;
• configuring a selected mapper of the OSM with a dynamic adjustment strategy, wherein the dynamic adjustment strategy is configured to allow the selected mapper to be injected with a temporary or conditional mapping behavior during runtime;
• wherein the injected temporary or conditional mapping behavior comprises an AdjustFieldBasedOnContext mapping behavior that causes the selected field mapper to map an entity field from the persistence layer to the domain model with a contextual value, regardless of the actual persisted data in the entity field;
• injecting into the selected mapper during runtime a temporary or conditional mapping behavior that is different from the original mapping strategy of the selected mapper;
• and
• mapping data via the selected mapper as per the temporary or conditional mapping behavior defined by the dynamic adjustment strategy.

• wherein the event comprises one of a connection to the persistence layer being unavailable, a migration of the persistence layer, and a mismatch data type between the domain model and the persistence layer;
• injecting into the selected field mapper during runtime a temporary or conditional mapping behavior that is different from the original mapping strategy of the selected field mapper;
