Process Driven Messaging Service
A process driven messaging service (PDMS) is a service that is process oriented and exchanges messages/data calls. A PDMS is a service where jobs and triggers can be put together to create a workflow for a message. Messaging platforms are considered key Internet infrastructure elements. A concept that once mainly encompassed email and IM has evolved to embrace complex multi-media email, instant messaging, and related fixed and mobile messaging infrastructure. Arguably, everything transmitted on the Internet and wireless telecommunication links are messages. PDMS exchanges messages for the purpose of all kind of messages/data calls between systems, applications and or human beings that is based upon event-driven process chains. Structure A process driven messaging service is a service where jobs and triggers can be put together to create a workflow for a message and the workflow can be seen as a process. A workflow is executed when a trigger is prompted. The trigger causes the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internet Messaging Platform
An Internet messaging platform is any system on the Internet that exchanges messages for the purpose of human communications. Messaging platforms are considered one of few key Internet infrastructure elements. What used to be only referred to as email and IM has evolved into a complex multi-media email, instant messaging, and related fixed and mobile messaging infrastructure. One can argue that everything transmitted on the Internet and wireless telecommunication links is a message of one sort or another. History In the beginning there was Sendmail and many other mail delivery agents soon followed ( Postfix etc.) Once email spam and computer virus problems started becoming prevalent in the early 1990s. These critical Internet infrastructure systems had to be patched and the underlying protocols changed -or in some cases ignored- to deal with these issues. - By European Institute for Research and Strategic Studies in Telecommunications. Thus was born the messaging platform. Large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Machine-to-Machine
Machine to machine (M2M) is direct communication between devices using any communications channel, including wired and wireless. Machine to machine communication can include industrial instrumentation, enabling a sensor or meter to communicate the information it records (such as temperature, inventory level, etc.) to application software that can use it (for example, adjusting an industrial process based on temperature or placing orders to replenish inventory). Such communication was originally accomplished by having a remote network of machines relay information back to a central hub for analysis, which would then be rerouted into a system like a personal computer. More recent machine to machine communication has changed into a system of networks that transmits data to personal appliances. The expansion of IP networks around the world has made machine to machine communication quicker and easier while using less power. These networks also allow new business opportunities for consum ...

Enterprise Application Integration
Enterprise application integration (EAI) is the use of software and computer systems' architectural principles to integrate a set of enterprise computer applications. Overview Enterprise application integration is an integration framework composed of a collection of technologies and services which form a middleware or "middleware framework" to enable integration of systems and applications across an enterprise. Many types of business software such as supply chain management applications, ERP systems, CRM applications for managing customers, business intelligence applications, payroll, and human resources systems typically cannot communicate with one another in order to share data or business rules. For this reason, such applications are sometimes referred to as islands of automation or information silos. This lack of communication leads to inefficiencies, wherein identical data are stored in multiple locations, or straightforward processes are unable to be automated. Enter ...

Message Transfer Agents
Within the Internet email system, a message transfer agent (MTA), or mail transfer agent, or mail relay is software that transfers electronic mail messages from one computer to another using SMTP. The terms mail server, mail exchanger, and MX host are also used in some contexts. Messages exchanged across networks are passed between mail servers, including any attached data files (such as images, multimedia or documents). These servers also often keep mailboxes for email. Access to this email by end users is typically either via webmail or an email client. Operation A message transfer agent receives mail from either another MTA, a mail submission agent (MSA), or a mail user agent (MUA). The transmission details are specified by the Simple Mail Transfer Protocol (SMTP). When a recipient mailbox of a message is not hosted locally, the message is relayed, that is, forwarded to another MTA. Every time an MTA receives an email message, it adds a trace header field to the top of the he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Workflow
A workflow consists of an orchestrated and repeatable pattern of activity, enabled by the systematic organization of resources into processes that transform materials, provide services, or process information. It can be depicted as a sequence of operations, the work of a person or group, the work of an organization of staff, or one or more simple or complex mechanisms. From a more abstract or higher-level perspective, workflow may be considered a view or representation of real work. The flow being described may refer to a document, service, or product that is being transferred from one step to another. Workflows may be viewed as one fundamental building block to be combined with other parts of an organization's structure such as information technology, teams, projects and hierarchies. Historical development The development of the concept of a workflow occurred above a series of loosely defined, overlapping eras. Beginnings in manufacturing The modern history of workflows ca ...

Process Mining
Process mining is a family of techniques relating the fields of data science and process management to support the analysis of operational processes based on event logs. The goal of process mining is to turn event data into insights and actions. Process mining is an integral part of data science, fueled by the availability of event data and the desire to improve processes. Process mining techniques use event data to show what people, machines, and organizations are really doing. Process mining provides novel insights that can be used to identify the executional path taken by operational processes and address their performance and compliance problems. Process mining starts from event data. Input for process mining is an event log. An event log views a process from a particular angle. Each event in the log should contain (1) a unique identifier for a particular process instance (called case id), (2) an activity (description of the event that is occurring), and (3) a timestamp. There ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Loose Coupling
In computing and systems design, a loosely coupled system is one # in which components are weakly associated (have breakable relationships) with each other, and thus changes in one component least affect existence or performance of another component. # in which each of its components has, or makes use of, little or no knowledge of the definitions of other separate components. Subareas include the coupling of classes, interfaces, data, and services. Loose coupling is the opposite of tight coupling. Advantages and disadvantages Components in a loosely coupled system can be replaced with alternative implementations that provide the same services. Components in a loosely coupled system are less constrained to the same platform, language, operating system, or build environment. If systems are decoupled in time, it is difficult to also provide transactional integrity; additional coordination protocols are required. Data replication across different systems provides loose coupling (i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Short Message Service
Short Message/Messaging Service, commonly abbreviated as SMS, is a text messaging service component of most telephone, Internet and mobile device systems. It uses standardized communication protocols that let mobile devices exchange short text messages. An intermediary service can facilitate a text-to-voice conversion to be sent to landlines. SMS technology originated from radio telegraphy in radio memo pagers that used standardized phone protocols. These were defined in 1986 as part of the Global System for Mobile Communications (GSM) series of standards.GSM Doc 28/85 "Services and Facilities to be provided in the GSM System" rev2, June 1985 The first SMS message was sent on 3 December 1992, when Neil Papworth, a test engineer for Sema Group, sent "Merry Christmas" to the Orbitel 901 phone of colleague Richard Jarvis. SMS rolled out commercially on many cellular networks that decade and became hugely popular worldwide as a method of text communication. By the end of 2010, SMS ...

Critical Internet Infrastructure
__NOTOC__ Critical Internet infrastructure is a collective term for all hardware and software systems that constitute essential components in the operation of the Internet. Background Several studies and events have helped to define the scope of critical Internet infrastructure. In August 2013, Internet infrastructure experts including Yuval Shavitt, Bill Woodcock, Rossella Mattioli, Thomas Haeberlen, Ethan Katz-Bassett and Roland Dobbins convened for six days at Schloss Dagstuhl to refine the academic and policy understanding of critical Internet infrastructure, producing a number of papers in the process. In 2017, the Global Commission on the Stability of Cyberspace undertook a global survey of Internet infrastructure experts in order to assess the degree of consensus on what constituted critical Internet infrastructure, producing a '' Definition of the Public Core'' which has since been used by the OECD and others as a standardized description of the principal elements of Inter ...

Service (systems Architecture)
In the contexts of software architecture, service-orientation and service-oriented architecture, the term service refers to a software functionality, or a set of software functionalities (such as the retrieval of specified information or the execution of a set of operations) with a purpose that different clients can reuse for different purposes, together with the policies that should control its usage (based on the identity of the client requesting the service, for example). OASIS defines a service as "a mechanism to enable access to one or more capabilities, where the access is provided using a prescribed interface and is exercised consistent with constraints and policies as specified by the service description".

Architectural Pattern
An architectural pattern is a general, reusable solution to a commonly occurring problem in software architecture within a given context. The architectural patterns address various issues in software engineering, such as computer hardware performance limitations, high availability and minimization of a business risk. Some architectural patterns have been implemented within software frameworks. The use of the word "pattern" in the software industry was influenced by similar concepts as expressed in traditional architecture, such as Christopher Alexander's ''A Pattern Language'' (1977) which discussed the practice in terms of establishing a pattern lexicon, prompting the practitioners of computer science to contemplate their own design lexicon. Usage of this metaphor within the software engineering profession became commonplace after the publication of ''Design Patterns'' (1994) by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides—now commonly known as the "Gang of F ...
