An apparatus and method for deleting objects from an object-relational system in a customizable and database independent manner. The apparatus and method provide a customizable and database independent mechanism for the deletion of object data from a relational database. The method implemented by the apparatus determines the dependency structure of a relational database using database metadata. The dependency structure is then utilized to determine the type of deletion to be performed on data representations of the object and its related objects, i.e., parent or child objects. The deletion actions include cascade deletion and nullify columns deletion. Appropriate SQL statements are then automatically generated at run-time to perform the deletion of the object data from the relational database.

A system stores records of different entity types and processes search queries to determine search results comprising records that match the search query. The system receives a search query comprising search keywords from a source user. The system identifies a target user based on a search keyword received in the search query. The system determines a relationship between the source user and the target user. The system determines a relationship strength score for the relationship between the source user and the target user and ranks the search results based on the relationship strength score. The system provides the search results to the source user.

Methods and systems for identifying and maintaining relationships in a network of peer-to-peer enterprise information systems that include a unified entity-relationship system that has a number of entities, each of which has a number of attributes. Subsumed entity-relationship systems are coupled to the unified entity-relationship system, and the entities of the unified entity-relationship system are mapped to one another and to entities and attributes of entities of the subsumed entity-relationship systems. A join engine is coupled to the unified entity-relationship system for performing joins and splits to form related entities and an object model that is coupled to the join engine is available globally throughout the network. The object model contains the mapped relationships and is deployed in conjunction with a join model, the join model specifying transformations and queries required for forming an entity from a set of related entities.

Embodiments are directed to incrementally upgrading an entity-relationship system. In an embodiment, a computer system receives an indication that one instance including its own specified set of entities is to be upgraded to a second instance including a different specified set of entities. The computer system accesses the two instances to determine the differences between the entities of each instance. The computer system then discovers, based on the determined differences between the two instances, a set of actions that, when executed, change the entities of the first instance to the entities of the second instance. The set of actions is ordered such that processing order constraints are respected. The computer system then incrementally upgrades the entities of the first instance to the entities of the second instance by processing the determined set of actions in the appropriate, constraint-aware order.
