In most cases, end-users are the customers using the product. A URL (uniform resource locator) is a unique identifier used to locate a resource on the internet. Also known as a web address. A Property ID is the unique field ID used by Unqork to track and link components in your module. Label Text conveys what the input component is and what information it displays. Enter the purpose of the corresponding component or field. End-users, also known as Express Users, are the individuals accessing an application through Express View. In most cases, end-users are the customers using the product. The Number data type accepts integer or floating point values. The number data type does not use quotes around numerical values. HTML (Hyper Text Markup Language) is the standard markup language for for achieving font, color, graphic, and hyperlink effects when creating web pages. Rendering is the process of loading components and displaying the final result on the front-end screen. The VCS (version control system) Contributor role has permissions to edit modules in a branch. Set contributors during the VCS Create a Branch process. Label Text conveys what the input component is and what information it displays. Enter the purpose of the corresponding component or field. An API endpoint is the location where an API receives requests for a specific resource on its server. It's the point of contact between an API client and an API server, and is usually a uniform resource locator (URL) that provides the location of the resource. HTTP (Hypertext Transfer Protocol) is an application-layer protocol used to transmit hypermedia documents like HTML. Fetching is the process of retrieving data from a database, making it available to the application and the end-user. JSON (JavaScript Object Notation) is an open standard file and data interchange format. Unqork uses JSON for submission (record) data. An array is a type of object that stores one or more data types. Data types supported in arrays include numbers, strings, and objects. A JavaScript property is a member of an object that associates a key with a value. A JavaScript object is a data structure that stores a collection of properties. A query lets you retrieve, access, manipulate, and delete data in a database. A string is an object that represents a sequence of characters. Strings typically hold data represented in text form. End-users, also known as Express Users, are the individuals accessing an application through Express View. In most cases, end-users are the customers using the product. APIs (application programming interfaces) are a set of protocols and definitions developers use to build and integrate application software. APIs act as the connective tissue between products and services. Also known as Record Data. Submission data consists of information saved by Unqork components. View submission data by using the angular command, or in Record Collections. Cascading Style Sheets (CSS) is a style sheet language used for presenting how a HTML or XML document looks to end-users.
