An educational programming language and development environment, designed to help young students start programming by building 3D animations and games. It is currently available in English, Hebrew, Yiddish, and Chinese. MS Word and MS Excel. Their macro languages used to be localized in non-English languages.
Surrogate key. A surrogate key (or synthetic key, pseudokey, entity identifier, factless key, or technical key[citation needed]) in a database is a unique identifier for either an entity in the modeled world or an object in the database. The surrogate key is not derived from application data, unlike a natural (or business) key.
A foreign key is a set of attributes in a table that refers to the primary key of another table, linking these two tables. In the context of relational databases, a foreign key is subject to an inclusion dependency constraint that the tuples consisting of the foreign key attributes in one relation, R, must also exist in some other (not necessarily distinct) relation, S; furthermore that those ...
Python is a multi-paradigm programming language. Object-oriented programming and structured programming are fully supported, and many of their features support functional programming and aspect-oriented programming (including metaprogramming [ 70 ] and metaobjects). [ 71 ] Many other paradigms are supported via extensions, including design by ...
Key size. In cryptography, key size or key length refers to the number of bits in a key used by a cryptographic algorithm (such as a cipher). Key length defines the upper-bound on an algorithm's security (i.e. a logarithmic measure of the fastest known attack against an algorithm), because the security of all algorithms can be violated by brute ...
Fig. 1: A binary search tree of size 9 and depth 3, with 8 at the root. In computer science, a binary search tree (BST), also called an ordered or sorted binary tree, is a rooted binary tree data structure with the key of each internal node being greater than all the keys in the respective node's left subtree and less than the ones in its right subtree.
Foreign function interface. A foreign function interface (FFI) is a mechanism by which a program written in one programming language can call routines or make use of services written or compiled in another one. An FFI is often used in contexts where calls are made into a binary dynamic-link library.
A typical 105-key computer keyboard, consisting of sections with different types of keys. A computer keyboard consists of alphanumeric or character keys for typing, modifier keys for altering the functions of other keys, [1] navigation keys for moving the text cursor on the screen, function keys and system command keys—such as Esc and Break—for special actions, and often a numeric keypad ...
