Dragan Gaševic, Dragan Djuric, Vladan Devedžic, Bran V.'s Model Driven Architecture and Ontology Development PDF

Defining a proper area ontology is mostly thought of an invaluable, to not say beneficial step in virtually each software program venture. it is because software program offers with rules instead of with self-evident actual artefacts. although, this improvement step is infrequently performed, as ontologies depend on well-defined and semantically robust AI innovations corresponding to description logics or rule-based structures, and so much software program engineers are principally surprising with those.

Example text

Why must browsers use an event queue to process events? 1 The lifecycle overview The lifecycle of a typical client-side web application begins with the user typing a URL into the browser’s address bar or clicking a link. Let’s say we want to look up a term and go to Google’s homepage. 1. 1 The lifecycle of a clientside web application starts with the user specifying a website address (or clicking a link) and ends when the user leaves the web page. It’s composed of two steps: page building and event handling.

We use JavaScript code to dynamically modify the DOM to bring dynamic behavior to web applications. The execution of client-side web applications is performed in two phases: – Page building—HTML code is processed to create the DOM, and global JavaScript code is executed when script nodes are encountered. During this execution, the JavaScript code can modify the current DOM to any degree and can even register event handlers—functions that are executed when a particular event occurs (for example, a mouse click or a keyboard press).

It’s important to note that, unlike us, some people believe that a callback has to be called asynchronously, and therefore that the first example isn’t really a callback. We mention this just in case you stumble upon some heated discussion. NOTE Now let’s consider a use of callbacks that will greatly simplify how we sort collections. SORTING WITH A COMPARATOR Almost as soon as we have a collection of data, odds are we’re going to need to sort it. Let’s say that we have an array of numbers in a random order: 0, 3, 2, 5, 7, 4, 8, 1.
