What is declarative programming? [closed]

穿精又带淫゛_ 提交于 2020-01-09 04:00:33
问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 4 years ago . I keep hearing this term tossed around in several different contexts. What is it? 回答1: Declarative programming is when you write your code in such a way that it describes what you want to do, and not how you want to do it. It is left up to the compiler to figure out the how.

What is a data binding?

问题 What is a data binding? 回答1: Binding generally refers to a mapping of one thing to another - i.e. a datasource to a presentation object. It can typically refer to binding data from a database, or similar source (XML file, web service etc) to a presentation control or element - think list or table in HTML, combo box or data grid in desktop software. You generally have to bind the presentation element to the datasource, not the other way around. This would involve some kind of mapping - i.e.

What constitutes 'real time'

左心房为你撑大大i 提交于 2019-12-22 03:44:48
问题 I am having trouble deciding on whether to classify my application as 'real time' or 'near real time', or perhaps even something else. The software receives data immediately as it is generated from the source, then based on certain rules, raises an alert when certain conditions are met. It takes the approach of checking the last 30 seconds of data every 30 seconds to see whether the criteria for a rule has been met. Is that real time? What are the thresholds for the definitions of real time

Schema.org for acronym / abbreviation (in a glossary)

牧云@^-^@ 提交于 2019-12-20 05:12:07
问题 I'd like to mark my list of acronyms/abbreviations in my glossary of my website with Schema.org (using Microdata). Which type of Schema.org is the right one for that? I can't find any related type in the full list on schema.org. 回答1: The type DefinedTerm (which is currently in Pending, so it’s subject to change) is suitable for a word, name, acronym, phrase, etc. with a formal definition In a glossary, you would use the name property for the term, and the description property for what the

Simple explanation of MapReduce?

久未见 提交于 2019-12-17 15:21:37
问题 Related to my CouchDB question. Can anyone explain MapReduce in terms a numbnuts could understand? 回答1: Going all the way down to the basics for Map and Reduce. Map is a function which "transforms" items in some kind of list to another kind of item and put them back in the same kind of list. suppose I have a list of numbers: [1,2,3] and I want to double every number, in this case, the function to "double every number" is function x = x * 2. And without mappings, I could write a simple loop,

What is the difference between Type and Class?

拜拜、爱过 提交于 2019-12-17 05:16:14
问题 What makes a type different from class and vice versa? (In the general language-agnostic sense) 回答1: The following answer is from Gof book (Design Patterns) An object's class defines how the object is implemented .The class defines object's internal state and the implementation of its operations. In contrast, an object's type only refers to its interface - a set of requests to which it can respond. An object can have many types, and objects of different classes can have the same type. /

What do “branch”, “tag” and “trunk” mean in Subversion repositories?

有些话、适合烂在心里 提交于 2019-12-16 19:56:26
问题 I've seen these words a lot around Subversion (and I guess general repository) discussions. I have been using SVN for my projects the last few years, but I've never grasped the complete concept of these directories. What do they mean? 回答1: Hmm, not sure I agree with Nick re tag being similar to a branch. A tag is just a marker Trunk would be the main body of development, originating from the start of the project until the present. Branch will be a copy of code derived from a certain point in

COBOL level 88 data type

蹲街弑〆低调 提交于 2019-12-08 02:45:33
问题 Very basic question here. I have to write out a data glossary for a COBOL program. This data glossary includes the following details about every variable: Name Data type Range of values (if applicable) Line numbers Fuller name I have several variables that include level 88 switches. My question is this: Are these level 88 switches counted as variables, and should I include them in the data glossary? Or, judging by the data glossary structure I have to work with, should they be ignored in this
