Core Idea¶

Data binding is treated here as the recurring computerscienceandinformation identity summarized by this source-grounded definition: In computer programming, data-binding is a general technique that binds data sources from the provider and consumer together and synchronizes them. In computer programming, data-binding is a general technique that binds data sources from the provider and consumer together and synchronizes them. This is usually done with two data/information sources with different languages, as in XML data binding and UI data binding.

The Magic String Scoreboard

Imagine a scoreboard tied to the real score with an invisible string. When a team scores, the board changes all by itself, so nobody has to run over and fix it. Sometimes the string works both ways: change the board, and the real score changes too.

Always-Matching Link

Computer programs often show information on a screen, like a name in a box, while also keeping that information stored inside the program. Data binding is a way of hooking the two together so they stay in sync by themselves. If the stored information changes, the box on the screen updates automatically. It can also work the other way: if you type a new name into the box, the stored information changes to match. Nobody has to copy the change over by hand.

Synchronized Data Links

Data binding is a programming technique that links a data source to something that uses or displays it and keeps them synchronized automatically. Without it, a programmer has to write code to copy every change from the data to the screen and back. With binding, a change to the underlying data is reflected in every element bound to it, and in two-way binding, editing an on-screen element such as a text box updates the underlying data too. The two sides are often different kinds of things, like a screen widget and a data object, or an XML document and program objects. The key idea is ongoing synchronization, not a one-time copy.

Data binding is a general technique that binds a provider's data source to a consumer and keeps them synchronized, so that neither side has to be updated by explicit copying code. The two sides are often expressed in different languages or representations, as in XML data binding, where document structures are mapped onto program objects. In UI data binding the two sides can be in the same language but play different logical roles, for example Java UI widgets bound to Java model objects. The defining behavior is automatic propagation: a change to the data is reflected by every element bound to it. Binding can also be reverse or two-way, where a change to the outer representation, such as a TextBox edit, updates the underlying data value. What makes something data binding is the maintained synchronization relationship itself, not merely displaying data once or sharing a variable name.

Scope of Application¶

Documented setting. In UI data binding, data and information objects of the same language, but different logic function are bound together (e.g., Java UI elements to Java objects).
Documented setting. The term data binding is also used in cases where an outer representation of data in an element changes, and the underlying data is automatically updated to reflect this change.

Clarity¶

A clear use of Data binding names the carrier, the operative relation, and the conditions under which the source treats the identity as present. The minimal definition is In computer programming, data-binding is a general technique that binds data sources from the provider and consumer together and synchronizes them.

Manages Complexity¶

Data binding compresses multiple computerscienceandinformation details into a stable diagnostic relation. The source shows both the central mechanism—list of examples of data binding frameworks and tools for different programming languages.—and the practical consequence—the term data binding is also used in cases where an outer representation of data in an element changes, and the underlying data is automatically updated to reflect this change.

Abstract Reasoning¶

Type the carrier. Identify the computerscienceandinformation entities to which the claim applies.
State the relation. Use the source-grounded identity: In computer programming, data-binding is a general technique that binds data sources from the provider and consumer together and synchronizes them.
Check operation and conditions. In computer programming, data-binding is a general technique that binds data sources from the provider and consumer together and synchronizes them.
Demand recognition evidence.

Knowledge Transfer¶

Within the home domain. Knowledge about Data binding transfers literally when a new case preserves the same carrier type, relation, and recognition test. In UI data binding, data and information objects of the same language, but different logic function are bound together (e.g., Java UI elements to Java objects). The term data binding is also used in cases where an outer representation of data in an element changes, and the underlying data is automatically updated to reflect this change. Beyond the home domain. No canonical parent is asserted for Data binding.

Neighborhood in Abstraction Space¶

Data binding sits in a sparse region of the domain-specific corpus (68^th percentile for distinctiveness): few abstractions share its structure, so a faithful description tends to retrieve it precisely.
