A method of contextual modification of data sharing constraints is disclosed. The method comprises receiving a data sharing request to share a first data model with a database associated with a second data model; generating a shareable version of the first data model in response to the data sharing request; determining a parameter value used to perform a data model merging operation to merge the shareable version of the first data model with the second data model, the parameter value indicating whether to execute or skip a particular process during the data model merging operation; determining context data for the data model merging operation based on the generating; modifying the parameter value based on the context data; performing the data model merging operation using the modified parameter value.

Contextual modification of data sharing constraints in a distributed database system that uses a multi-master replication scheme

A computer-implemented method of context-based constraint modification is disclosed. The method comprises receiving a data sharing request in a distributed database system to share a data model between databases. The method further comprises adjusting a data sharing constraint applicable to the data sharing request based on data related to previous data sharing processes, the data sharing constraint being related to data transmission or validation, access control, or conflict resolution. The method additional comprises determining that the data sharing request requires data merging; reading a data file containing a shareable version of at least a portion of the data model subject to the data sharing constraint; and merging the shareable version with a current data model for a database of the databases.

Systems and methods are provided for storing a first data object comprising a first set of immutable components, the first data object being associated with a corresponding second data object stored by a remote replication system. A difference is determined between the first set of immutable components of the first data object and a second set of immutable components of the corresponding second data object. A subset of immutable components is identified from the first set of immutable components based on the difference. The subset of immutable components from the first set of immutable components is provided to the remote replication system over a communication network.

Systems and methods for data replication synchronization

A system and method providing cross-ontology multi-master replication is described. In a first embodiment a method for cross-ontology multi-master replication comprising the steps of: storing a database change comprising a property value, the property value having an exporting site property type as defined in an exporting site ontology for an exporting site; using an ontology map to map the exporting site property type to an importing site property type defined by an importing site ontology for an importing site; transforming the property value to an intermediate property value based on the importing site property type; transforming the intermediate property value to a first round-trip value based on the exporting site property type; and determining whether to export the database change to the importing site based at least in part on a comparison between the property value and the first round-trip value.

Cross-ontology multi-master replication

Techniques for contextual modification of data sharing constraints in a distributed database system are disclosed. The constraint modifications can improve data sharing processes, particularly in applications that involve cross-model data sharing and/or have a need for low data latency.

A computer-based method and system for sharing and deconflicting data changes amongst a plurality of replication sites. In a particular embodiment, data changes at sites to data objects are tracked by each site on a per-data object basis using per-data object version vectors. In another particular embodiment, data changes at sites to links connecting two data objects are tracked by each site on a per-link set basis using per-link set version vectors. In another particular embodiment, per-object version vectors are used to detect a conflict resulting from concurrent changes at two or more sites in which one of the concurrent changes includes an object resolution change.

Sharing and deconflicting data changes in a multimaster database system

Techniques for cross-ACL multi-master replication are provided. The techniques allow a replication site in a multi-master replication system implementing an asynchronous replication protocol and an access control policy to appropriately apply received data change updates to data maintained at the site even where a data change update is missing information because of the implemented access control policy.

Cross-ACL multi-master replication

Approaches for displaying a user interface including a map based on interaction data are disclosed. A set of interaction data and can be acquired and stored in a data structure. This data can be associated with a plurality of consuming entities that may have purchased something during these interactions. A set of provisioning entities can be determined based on spending or purchasing habits of the consuming entities. Based on this set of provisioning entities, a user interface can be generated which may include various shapes similar to a heat map. These shapes can indicate an average amount spent in a particular neighborhood, among other attributes.

Methods and systems for determining location information

Approaches for analyzing entity performance are disclosed. A first set of data and a second set of data can be stored in a data structure. This data can be associated with a plurality of interactions, and can be modified to include additional interactions. These interactions can involve consuming entities and provisioning entities. The modified data structure can be queried to retrieve information associated with one or more entities. After information is retrieved, it can be provided to a user.

Methods and systems for analyzing entity performance

A system and method providing cross-ontology multi-master replication is described. In a first embodiment a method for cross-ontology multi-master replication comprising the steps of: obtaining, at an importing site, an exporting site ontology and a set of one or more database changes; wherein the exporting site ontology defines a set of one or more data types; and after mapping the exporting site ontology to an importing site ontology, incorporating the set of one or more database changes into a database including mapping each of one or more data types of the set of data types to a data type defined by the importing site ontology using an ontology map.
