ühenduspalett

Ühenduspalett is a visual component used primarily in graphical modeling and integration environments to represent and manage connections between individual modules or components. It appears as a palette of icons, connectors, or drag‑and‑drop elements that enable users to create links, define data flows, and configure interaction logic without writing code. The term is derived from Estonian, meaning “connection palette.”

The concept was first introduced in the mid‑2010s as part of the e‑government and enterprise application ecosystems in Estonia, where integration of legacy systems required a user‑friendly interface for service orchestration. It was later adopted by other low‑code platforms and workflow editors, such as the Odoo community version and various business‑process‑management tools.

Typical features of a ühenduspalett include: a representation of available endpoints (services, databases, APIs), visual connectors that may display data type or protocol information, drag‑and‑drop functionality for creating new links, automatic validation of connection rules, and a configuration panel for setting parameters such as authentication and filtering. In some implementations, the palette also supports real‑time collaboration and version control integration.

Users of task‑oriented systems like the Estonian Tax and Customs Board’s “ETL” tools employ the ühenduspalett to assemble data pipelines, while business analysts at mid‑size enterprises use it to model sales‑to‑logistics workflows. In educational contexts, the palette is used in teaching data‑integration concepts, allowing students to visualize how external APIs interact with internal databases.

While the core idea remains the same, specific implementations differ in UI style, supported connector types, and integration depth. Common frameworks that expose a similar functionality include Power Automate’s connector visualizer, Node‑RED’s drag‑and‑drop UI, and the Odoo “Connection Palette” in its e‑commerce and hybrid commerce modules.
