Join-pattern
Join-patterns provides a way to write concurrent, parallel and distributed computer programs by message passing. Compared to the use of threads and locks, this is a high level programming model using communication constructs model to abstract the complexity of concurrent environment and to allow scalability. Its focus is on the execution of a chord between messages atomically consumed from a group of channels. This template is based on join-calculus and uses pattern matching. Concretely, this is done by allowing the join definition of several functions and/or channels by matching concurrent call and messages patterns. It is a type of concurrency pattern because it makes easier and more flexible for these entities to communicate and deal with the multi-threaded programming paradigm. Description The join-pattern (or a chord in Cω) is like a super pipeline with synchronisation and matching. In fact, this concept is summarise by match and join a set of message available ...

Join (SQL)
A join clause in the Structured Query Language (SQL) combines column (database), columns from one or more table (database), tables into a new table. The operation corresponds to a Join (relational algebra), join operation in relational algebra. Informally, a join stitches two tables and puts on the same row records with matching fields : INNER, LEFT OUTER, RIGHT OUTER, FULL OUTER and CROSS. Example tables To explain join types, the rest of this article uses the following tables: Department.DepartmentID is the primary key of the Department table, whereas Employee.DepartmentID is a foreign key. Note that in Employee, "Williams" has not yet been assigned to a department. Also, no employees have been assigned to the "Marketing" department. These are the SQL statements to create the above tables: CREATE TABLE department( DepartmentID INT PRIMARY KEY NOT NULL, DepartmentName VARCHAR(20) ); CREATE TABLE employee ( LastName VARCHAR(20), DepartmentID INT REFERENCE ...

Join-calculus
The join-calculus is a process calculus developed at INRIA. The join-calculus was developed to provide a formal basis for the design of distributed programming languages, and therefore intentionally avoids communications constructs found in other process calculi, such as rendezvous communications, which are difficult to implement in a distributed setting. Despite this limitation, the join-calculus is as expressive as the full π-calculus. Encodings of the π-calculus in the join-calculus, and vice versa, have been demonstrated. The join-calculus is a member of the π-calculus family of process calculi, and can be considered, at its core, an asynchronous π-calculus with several strong restrictions: *Scope restriction, reception, and replicated reception are syntactically merged into a single construct, the ''definition''; *Communication occurs only on defined names; *For every defined name there is exactly one replicated reception. However, as a language for programming, the join-ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Join (law)
In law, a joinder is the joining of two or more legal issues together. Procedurally, a joinder allows multiple issues to be heard in one hearing or trial and occurs if the issues or parties involved overlap sufficiently to make the process more efficient or fairer. That helps courts avoid hearing the same facts multiple times or seeing the same parties return to court separately for each of their legal disputes. The term is also used in the realm of contracts to describe the joining of new parties to an existing agreement. Criminal procedure Joinder in criminal law is the inclusion of additional counts or additional defendants on an indictment. In English law, charges for any offence may be joined in the same indictment if those charges are founded on the same facts or form or are a part of a series of offences of the same or a similar nature. A number of defendants may be joined in the same indictment even if no single count applies to all of them if the counts are sufficientl ...

Joins (concurrency Library)
Joins is an asynchronous concurrent computing Application Programming Interface, API (Join-pattern) from Microsoft Research for the .NET Framework. It is based on join calculus and makes the concurrency constructs of the Cω language available as a Assembly (CLI), CLI assembly that any List of CLI languages, CLI compliant language can use. Overview Joins can be used to express concurrency in an application using the joins pattern, usable both for multi-threaded applications as well as for event based distributed computing, distributed applications. The Joins API emulates declarative type safety, type-safe expression of synchronization patterns. The Joins library emulates asynchronous and synchronous methods. An asynchronous method, in Cω and Joins parlance, is one which does not block the caller method, nor does it return any result, whereas a synchronous method blocks the caller method. In the Joins API, synchronous as well as asynchronous methods are implemented as generic prog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Join (simplicial Sets)
In higher category theory in mathematics, the join of simplicial sets is an operation making the category of simplicial sets into a monoidal category. In particular, it takes two simplicial sets to construct another simplicial set. It is closely related to the diamond operation and used in the construction of the twisted diagonal. Under the nerve construction, it corresponds to the join of categories and under the geometric realization, it corresponds to the join of topological spaces. Definition For natural numbers m,p,q\in\mathbb, one has the identity:Cisinski 2019, 3.4.12. : \operatorname( +q+1 =\prod_\operatorname( \times\operatorname( , which can be extended by colimits to a functor a functor -*-\colon \mathbf\times\mathbf\rightarrow \mathbf, which together with the empty simplicial set as unit element makes the category of simplicial sets \mathbf into a monoidal category. For simplicial set X and Y, their ''join'' X*Y is the simplicial set: : (X*Y)_n =\prod_X_ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
