SOA   -   In software engineering, a Service-oriented Architecture (SOA) leverages distributed and modular program components which communicate via a simple and lightweight communication "service" (hence the name). SOA solutions can be rapidly assembled from ad-hoc components, provide systems engineers with agile options in variable or evolving environments (such as health care), and yet SOA solutions also can be robust and scalable. SOA solutions are in contrast to monolithic or enterprise solutions, which may lack flexibility or adaptability.   See ESB, Grid, SOAP, WSDL, XML

SOAP   -   [1] The structured clinical note format which organizes content in Subjective, Objective, Assessment and Planning (SOAP) categories, first proposed in 1968 by Lawrence Weed, MD, as a feature of the Problem-Oriented Medical Record (POMR). [2] Simple Object Access Protocol, a distributed message processing solution used extensively to transport data between different and incompatible computer systems.   See POMR, REST, UDDI

Software   -   Informal term for a computer program.   See Application, Source Code

Source Code   -   In computing, source code is a collection of computer instructions written in a human-readable computer programming language. Source code facilitates the work of computer programming. Typically source code is transformed by a program known as a compiler into executable machine code understood by the computer. Alternatively, interpreters exist that allow a computer to run directly from source code. Most computer applications (programs) are distributed as condensed executable files without the source code. If the source code were included, it would enable a user, programmer, or system administrator to modify the software program as needed. For example, Mirth Connect, the enterprise software program used by Redwood MedNet, is written in the Java programming language.   See Compiler, Executable, FOSS, Java, Language, Open Source, Program, Software

SOW   -   Scope of work.   See WBS

Specificity   -   Optimizing for the maximum percent of data elements correctly identified as not-matching a given attribute (i.e., true negatives) out of all possible incorrect data element matches. Specificity seeks to minimize the occurrence of false positives.   See Disambiguate, False Positive, Recall, Sensitivity

Spider   -   Short for "Web Spider" and synonymous with web crawler.   See Bot, Web Crawler

Spoke   -   Term used by some vendors (e.g., eCW, e-MDs) to describe a software feature that allows a data payload to be exported from or imported into a clinical software application.   See Channel, EHR

Spyware   -   Malicious software designed to covertly spy on a user.   See Malware

SQL   -   Structured Query Language.   See CRUD, DBMS, NoSQL

SSH   -   Abbreviation for Secure SHell, a cryptographically secured network protocol, defined by RFC 4250.   See RFC

SSL   -   Secure Sockets Layer was an encryption protocol which provided secure communication on the Internet. SSL was invented by Netscape for safely conducting electronic commerce and other private asset management transactions from an Internet browser. SSL was superceded in 2008 by TLS.   See HTTPS, SSH, TLS

SSN   -   Social Security Number.

SSO   -   Single Sign On.

Standard   -   A common English noun and adjective with discrete meanings in a wide variety of technical, cultural, and commercial settings. For example, an Internet Standard is a specification approved by the IETF.   See DSTU, FHIR, IETF, ISO, SDO

State Designated Entity   -   See SDE

Stateless Protocol   -   A stateless server observes a protocol that treats each request as an independent transaction that is unrelated to any previous request.   See HTTP, Protocol

Superconcept   -   A parent concept.   See Ancestor, Concept, Descendant, Hierarchy

Supply Chain   -   Provisioning of a supply chain encompasses planning and management of all tasks involved in sourcing, procurement, logistics, and transport of raw materials, sub-assemblies, and finished goods. Tasks include coordination and collaboration among participants, which can include suppliers, intermediaries, third-party value added service providers, and customers. Supply chain management is an integrating function with a primary goal of linking operational functions and processes within and across organizations into a cohesive and high-performing service. Redwood MedNet approaches clinical data interoperability as a just in time supply chain provisioning use case and not as a longitudinal clinical data repository (CDR) use case. All commercial HIE software is built for a CDR use case.   See CDR, Clinical Messaging, CRM, Data Repository, EDI, ERP, HIE, MRP, MRP-II

Swimlanes   -   A type of business process flow diagram in which activities are grouped into horizontal or vertical "swimlanes" by role or actor. For example, a swimlane diagram of a patient visit might separate individual tasks in the diagram into roles for Front Desk, Billing, Medical Assistant, Nurse, Provider, etc.   See Business Process, Workflow

Symbol   -   An object, picture, sound, or mark that represents something else by association. For example, a personal name is a symbol representing an individual. In formal logic, "symbol" refers to an idea, and a "mark" is a token instance of the symbol.   See Algorithm, Concept, Model, Signal

Synchronization   -   A noun describing the task of indexing two or more separate data tables so that they both contain the same records. For example, synchronizing an immunization registry with an HIE that covers the same geographic territory.   See Disambiguate

Syndrome   -   Generally, a combination of phenomena observed in association. In medicine a syndrome is the formal association of clinically recognizable characteristics, features, phenomena, signs or symptoms that often occur together, so that the presence of one or more features alerts the clinician to the possible presence of the others.   See Biosurveillance, Signal

Syntax   -   In computer science, the syntax of a programming language is the set of rules that define the combinations of symbols that are considered to be correctly structured programs in that language.

Syslog   -   The syslog protocol, defined in RFC 5424, is used to convey event notification messages. This protocol utilizes a layered architecture, which allows the use of any number of transport protocols for transmission of system logging (syslog) messages. It also provides a message format that allows vendor-specific extensions to be provided in a structured way.   See RFC
