Big data explosion has already happened and the situation is only going to exacerbate with such a high number of data sources and high-end technology prevalent everywhere, generating data at a frantic pace. One of the most important aspects of big data is being able to capture, process, and analyze data as it is happening in real-time to allow real-time business decisions. Alternate approaches must be investigated especially consisting of highly parallel and real-time computations for big data processing. The chapter presents RealSpec real-time specification language that may be used for the modeling of big data analytics due to the inherent language features needed for real-time big data processing such as concurrent processes, multi-threading, resource modeling, timing constraints, and exception handling. The chapter provides an overview of RealSpec and applies the language to a detailed big data event recognition case study to demonstrate language applicability to big data framework and analytics modeling.

Key Terms in this Chapter

RealSpec: A functional, declarative, and dataflow executable real-time specification language.

Parallel Computing: Computation of several sub-tasks concurrently to solve a large or complex task.

Dataflow Paradigm: Programming paradigm that models programs as directed graphs of the data flowing between operations.

Big Data Analytics: Process of examining large data sets containing a variety of data types for specific patterns, correlations, market trends, customer preferences and other relevant information.

Software Modeling: A high-level language used to build simplified prototypes of software systems.

Declarative Language: A non-procedural language where a program specifies what needs to be done rather than how to do.

Executable Specification Language: A software specification language with operational semantics.

Real-Time Specification Language: A language that allows specification of real-time software systems requirements.
