Evoke Glossary
Evoke
The software application that enables the design and generation of an App that can be used across all major mobile and desktop platforms.
App
The App that you wish to design and create with evoke.
Version
Each App designed and developed in evoke can have multiple versions, each autonomous. These can be duplicated from an existing App version or created as new apps.
Entities
Tables/File Structures that are used in evoke for the user interface. These may relate directly to database files/tables or be UI only data structures.
Properties
Fields/Properties within an Entity. Each property many have a datatype of AlphaNumeric, Boolean, Currency, Date, DateTime, Decimal, ImpagePath, Integer, Time, Classification, Entity. Some Properties may be UI usage only or calculated Properies.
Selections
Selections are the database selections used to identify specific records/Entities within a database file/table. Selections are the way you tell the database what specific sets of data/records you want read into Evoke for use in the UI or App. The selection may have filter arguments passed to it and is used within evoke.
Classifications
Static lists used to populate a field/property of a table in the evoke UI. e.g. to provide a drop down selection of product names, standard responses to questions, etc
Menu
The navigation menu structure that is defined for the app that is to be produced. Includes the Page Series that each menu item is linked to.
Page Series
The groups of pages, including which is the entry page used when the menu item is clicked, that relate to each menu item defined in the menu
Page
The individual screens (pages) in the resulting app. Pages are grouped in a Page Series.
DataSource
DataSources are the Entity types (Files/Tables/data Structures) that are associated by you with each Page Series for use in the Pages within.
Refined DataSource
Refined DataSources are a special type of DataSource that allows for advanced seraching, sorting and filtering against any DataSource from within Evoke or by the App User. Refined DataSources are linked to a DataSource within each Page Series.
Collection
Collection within Evoke defines if a DataSource is a collecton or series of records/information or just a single instance of a data structure/Entity.
AutoSaved
Autosaved relates to the DataSources and indicates, as a Boolean value, if the DataSource is able to be saved back from the UI to the backend Repository or not.
Template
Templates in evoke are the way data/information is structured in the User Interface (UI). A Template is bound with a base Entity type and the properatirs of this entity may be selected to be part of the UI. There are also multiple "unbound data" properties that can be attached for elements such as buttons or statis text. Each Property of a template can have its own Widget and specific instrcutions. Examples of Template use can be found in the demo Apps. Templates also link to the Click Actions that can add powerful additional functionality to each App.
Click Actions
Click Actions are powerful functional code inserts that can be bound to Headers, Template Properties and various other App elements to include a series of actions, as required within the App. Please see the Click Actions for a summary of the current Click Actions that are available.
Segment
Segments are the basic building block of the Page UI. Each App page is made up of Segments, which may be including within each other as child Segments and structured as rows of columns. Examples of Segments may be found in the demo Apps.
Widget
Widgets are the UI input/display/image control options that can be included within the App being built with evoke. Used together with Templates, inside Segments, they are fundemental to the App functions. Please refer to the Widget definitions page for a list of all the Widgets available.
Header
Each Segment can optionally have a Header, this is a title bar for each segment. If a header is chosen then Header Actions can be specified allowing standard Click Actions and additional standard actions such as new, delete, nudge, etc.
Adaptations
The Adaptations section in evoke is the area that different display options/actions can be set to various information, Grid, Segments etc depending upon the screen size/device that the app is being used on. Please refer to the Adaptations definitions page for a list of all the Adaptations available.
Widget ID
the Widget ID can be set for every Property in a Template, this identifier is then included in the generated Visual Studio code as a marker (hanger) to link custom code onto.
Grid
A Grid is the multi entity display area in the App UI that holds and displays a list of values e.g. for a list of products this could be the product name, product code, a description and the price. This information is shown on seperate lines of the grid (table).
Navigation
Navigation in evoke is the area for setting up specific segment header, grid row or grid header navigation through standard app submenus e.g. an elysis or greater than sign. Examples may be found in the demo apps
Links
Before pages and Templates there is sometimes a link (multiple pages) symbol. This means the page or template is linked elsewhere in the App. I amenu item on the elypsis helps identify where the page or template is linked. A link means the page or template is used by another page series and is a direct copy of this page or template - any change in the original or linked template/page will change the template page in all linked instances of it.
ToolTip
The tooltip, associated with each Property of a Template, is used in conjunction with a cursor, usually a pointer. The user hovers the pointer over an item in the App, without clicking it, and, if specified, tooltip appears as a small "hover box" with information about the item being hovered over.
Generator
The evoke Generator is the module that creates the Visual Studio or Xamarin Solution and associated projects. The Generator provides the association with a backend database and allows for the generation of the database CRUD layer.
Web
Within evoke, Web is the area for generating web apps. The generated Visual Studio/Xamarin solution is then used as a web app or combined with the evoke AppRunner to create an evokehybrid app.
Native
Within evoke, Native is the area for generating full native apps. The generated Visual Studio/Xamarin solution includes all the projects neccessary to compile/build complete native apps for all platforms.
Repositories
Repositories are the backend databases that are to be mapped onto the Entities. They are defined by their ID, technology (e.g. SQL or MultiValue), Platform (specific flavour of SQL/MultiValue), the connection method and any specific connection string.
Data Mappings
Data Mappings in evoke link the evoke Entities with the actual database data; providing the link between the evoke UI entities and the actual Database file. In this section data positions in the actual database file are linked to Entity Properties and specific Selection parameters are included for any evoke Selections.
CRUD
The Create Read Update Delete layer created by evoke when an App is Generated. To generate a new standard CRUD entry for an Entity (such as a Selection) there is a Generate Entity CRUD tick box in the Entoty Mappings section of the Generator. Two CRUD items are created per Entity/database file; a standard CRUD item with Create, Read, Update, delete functions and Selections generated from the information included in the App design, and a custom CRUD item that is not overwritten when new CRUD is generated. The custom CRUD allows a DBA to create and maintain advanced specific CRUD entries/selections.
EVLU
The licensing terms of Evoke require that App Designers create a table/file within your database called "EVLU". Additional information regarding the EVLU file is available in Important Startup Information.
