viewdefs

viewdefs is a term that can refer to different concepts depending on the context, but it most commonly relates to how data or user interface elements are presented. In software development, a "view definition" often describes the structure and behavior of a user interface component. This could be a specific screen, a part of a screen, or a set of data displayed in a particular way. These definitions dictate what information is shown, how it is organized, and how the user can interact with it.

For instance, in web development frameworks, viewdefs might be implemented using templating languages or declarative syntax. These definitions separate the presentation logic from the underlying data and business logic, promoting a cleaner architecture and easier maintenance. The view definition acts as a blueprint for rendering dynamic content.

In other contexts, viewdefs could relate to database views. A database view is a virtual table based on the result-set of a SQL statement. It contains rows and columns that are derived from one or more database tables. The view definition specifies the query that retrieves and presents the data. This allows users to access specific data in a simplified or aggregated format without directly querying the base tables. The definition ensures consistency in how that particular subset of data is accessed.
