The following terms include those that are Memento-specific and those that relate to the user of databases and mobile applications.
The following terms include those that are Memento-specific and those that relate to the user of databases and mobile applications.


; Aggregation : In Memento, the set of operations and views that apply to the entire library or to each entry group in the library as well as to the entire library. Operations include sum, average, maximum, and minimum. Views include showing entries from related libraries when they are related to the shown entries of the current library.
= Terms =
 
== A ==
; <div id=action></div>Action
: A JavaScript script stored within a library that is set to run upon the pressing of the Play icon (like a YouTube Play icon) by the user
: See [[Actions]]
 
; <div id=aggregation></div>Aggregation
: In Memento, the set of operations and views that apply to the entire library or to each entry group in the library as well as to the entire library. Operations include sum, average, maximum, and minimum. Views include showing entries from related libraries when they are related to the shown entries of the current library.
 
; <div id=autofill></div>Autofill
: In Memento, the act of filling in data from an appropriate external data source when an entry is created
 
== C ==
; <div id=calendar_view></div>Calendar view
: The [[#view|view]] of listed library entries in which the format of the list is that of a calendar of events.
 
; <div id=card></div>Card
: (Mobile term)
: Synonyms: [[#dialog|Dialog]], [[#form|Form]]<br/>In the mobile edition, a proper subset of a screen that pops up modally in front of a screen to support the collection of information or performance of a task, and upon completion, returns to the "underlying" screen. That is, it is ''modal''; when the card pops up, the user is in the card mode; when the card is completed or dismissed, the user is returned to the screen mode.
 
; <div id=cards_view></div>Cards view
: (Mobile feature)
: In the mobile edition, in '''''Card view''''', the Display of entries in a list in the form of cards, shown 2-up on the list screen, and showing the same information as is shown in '''''List view''''' &mdash; namely, thumbnail (if any), entry name, entry description, and entry status. ''See [[#view|View]].''
 
== D ==
; <div id=database></div>Database
: A general term for an organized set of data, gathered and organized for a purpose, generally comprising multiple libraries. One could consider the set of libraries within a Group to be a database; or perhaps each set of libraries that are linked together to formulate a solution; or the entire Memento Cloud for a given user.
 
; <div id=DBMS>DBMS
: (Relational database term)
: Stands for '''D'''ata'''B'''ase '''M'''anagement '''S'''ystem.
: A relational DBMS (or RDBMS) is an app, often a server app, that stores information on a database in a [[#Relational|relational]] manner and allows access to it using queries to the DBMS.
 
; <div id=dialog></div>Dialog
: Synonyms: [[#card|Card]], [[#form|Form]] (In Mobile Memento, the term ''card'' is preferred.)<br/>A proper subset of a screen that pops up modally "in front of" a screen to support the collection of information or performance of a task, and upon completion, returns to the "underlying" screen.
 
; <div id="display"></div>Display
: (Mobile term)
: In the '''mobile edition''', the way Memento is presented to the user, as a part of the device and its operating system. A app's screen is generally shown on the display.
 
; <div id=team></div>Dropdown panel
: A [[#panel|panel]] that consists of a button that drops a menu down, each item identifying a subordinate panel that will drop down, based on the name displayed in the dropdown menu item.
 
== E ==
; <div id=entry></div>Entry
: Synonyms: [[#record|Record]], [[#row|Row]]<br/>A unit of fielded data within a library<br/>An instance or occurrence of data across fields or columns
 
; <div id="entry color"></div>Entry color
: A way that works on both editions of Memento is to use a JavaScript field. Don't fear, as the script is the most trivial of trivial things, JavaScript-wise, though you do need to know what 6-character codes define what colors (though you really should learn that anyway).
 
: See a detailed explanation of color codes at [[About:Color codes]].
 
: For the color codes, look at '''''https://htmlcolorcodes.com/'''''. Scroll down liberally to get to a section suited to your interest.
 
: For a script, all you do is put down the color code in double-quotes. So, Medium Gray is '''"#808080"'''. Just look them up.
 
; <div id="entries list footer bar"></div>Entries List Footer Bar
: A display bar at the foot of a list of entries. It often includes the number of entries in the list and might contain aggregation information, as well.
: Context - [[Library Entries List screen|Entries List screen]]

: A display bar within a list of entries. It is a header bar for a sublist of entries whose grouping values match. It may contain the number of entries in the sublist and other aggregation information for the sublist.
