Jolie (programming language)

Jolie (programming language) is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Jolie (programming language) rather than just read about it. In short: Jolie (Java Orchestration Language Interpreter Engine) is an open-source programming language for developing distributed applications based on microservices. In the programming paradigm proposed with Jolie, each program is a service that can communicate with other programs by sending and receiving messages over a network.

Key takeaways

Jolie (programming language) belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Jolie (programming language) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Jolie (programming language) from memory before moving on to harder problems.

Reference excerpt

Jolie (Java Orchestration Language Interpreter Engine) is an open-source programming language for developing distributed applications based on microservices. In the programming paradigm proposed with Jolie, each program is a service that can communicate with other programs by sending and receiving messages over a network. Jolie supports an abstraction layer that allows services to communicate using different mediums, ranging from TCP/IP sockets to local in-memory communications between processes. Jolie is currently supported by an interpreter implemented in the Java language, which can be run in multiple operating systems including Linux-based operating systems, OS X, and Windows. The language comes with formal semantics, meaning that the execution of Jolie programs is mathematically defined. For this reason, Jolie is used in research for the investigation of language-based techniques for the development of distributed systems, and it is also used for teaching at some universities. The Jolie open source project was started by Fabrizio Montesi in 2006, as part of his studies at the University of Bologna. The project initially began as an implementation of the SOCK process calculus, a formal model proposed by Claudio Guidi et al. at the University of Bologna inspired by the CCS process calculus and the WS-BPEL programming language. Jolie extends SOCK with support for, e.g., tree-like data structures (inspired by XML, but with a syntax resembling that of C and Java), message types, typed session programming, integration with Java and JavaScript, code mobility, application containment, and web programming. A complete list of the project contributors is available at. The project is currently maintained by Fabrizio Montesi and its evolution is driven by Fabrizio Montesi and Claudio Guidi. Since it supports the orchestration of web services, Jolie is an alternative to XML-based orchestration languages such as WS-BPEL as it offers a concise (C-like) syntax for accessing XML-like data structures.

Worked examples

Example 1 — a first encounter with Jolie (programming language)

Start with the simplest possible case. Write down what Jolie (programming language) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Jolie (programming language) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Jolie (programming language) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Jolie (programming language)

In research: Jolie (programming language) appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Jolie (programming language) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Jolie (programming language) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Programming languages, so understanding it makes those chapters shorter.
In everyday life: Look for Jolie (programming language) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
