The time-series framework can be modeled to route measurements. The three basic measurement processing categorizations are the Input, Action and Output interface adapters. These base level adapters are called Iaon Adapters (pronounced “yo-wan” from Input/Action/Output Interface Adaptors). According to Codplex.com, these three adopter types perform basic time-series data operation as follows:
InputAdapters: “map” measurements from a data source (i.e., assigns a timestamp and an ID to measured values parsed from a stream of data such as a PMU data). Phasor Measurement Unit (PMU) is a device which measures phasors of current and voltage. Phasors are complex numbers that have magnitude and phase angle of the measured quantity (voltage and current in our case).
ActionAdapter: filter and sort measurements by time allowing adapter to take action on a synchronized set of data.
OutputAdapters: queue all measurements without sorting for processing.
The other content I learned is about Middlewares.
Middleware is computer software that connects software components. The software consists of a set of services that allows multiple processes running on one or more machines to interact. This technology evolved to provide for interoperability in support of the move to coherent distributed architectures, which are most often used to support and simplify complex distributed applications. The reason why I am learning about “yo-wan” adapters and middleware is because I will be designing and implementing part of a middleware that handles input/action/output adapters for the power grid's data (PMU data).
