Abstract: The systems and methods described herein relate to dynamic runtime modifications of an object-relational mapping behavior associated with a relational persistence layer. In various embodiments, access to a relational persistence layer, such as a relational database management system may be provided via an object-relational mapper (ORM). The ORM may map data from the relational persistence layer to an object-oriented domain model. The ORM may include a plurality of field mappers configured with an original mapping strategy to map an entity field from the relational persistence layer to the object-oriented domain model. One or more of the field mappers may be configured with a dynamic adjustment strategy that allows the selected field mapper(s) to be injected with a temporary or conditional mapping behavior. The dynamic adjustment strategy may be initialized with the field mapper at startup, while the injection of temporary or conditional mappings may be performed during runtime.

Abstract: A system can correlate derived metrics for system activity to determine problems and recommend solutions. Using a hierarchy of derived metrics from a set of raw metrics, a system can identify a problem, correlate related metrics and determine a recommended solution. For example, raw metrics can be collected about computing resources. Analyzers can process the raw metrics and outputs from other analyzers to gather metrics that include metrics derived from other metrics. When a problem symptom is discovered, derived metrics (and other metrics) can be correlated with the symptom to help identify the problem. Using the correlated metrics, a system can recommend a solution to an identified problem.

Abstract: Modular spinal prosthesis having one of both of adaptable and configurable components are provided. The modular spinal prosthesis described herein provide an artificial articular configuration to replace damaged, worn or otherwise removed spinal facet elements. The prosthesis can include a crossbar having first and second ends. A first caudal prosthesis can be attached to the first end of the crossbar, while a second caudal prosthesis can be attached to the second end of the crossbar. A first crossbar mount can be positioned on the crossbar near the first caudal prosthesis, while a second crossbar mount can be positioned on the crossbar near the second caudal prosthesis. A first cephalad prosthesis can extend from the first crossbar mount, while a second cephalad prosthesis can extend from the second crossbar mount.
