  • Publication number: 20240111735
    Abstract: A data dictionary generation system automatically populates and updates a data dictionary for listings offering shared data. A data dictionary includes metadata describing the shared data, including the individual objects, such as the individual tables, schemas, views, and functions. The shared data and each individual data object may be described in the data dictionary by a set of data fields that corresponds to the shared dataset or the object type of the individual object. The data dictionary can be presented to data consumers along with the description of the listing to provide data consumers with a comprehensive description of the shared data provided by a listing, including a high-level summary of the shared data and description of each individual object included in the shared data. The data dictionary allows data consumers to understand the contents of the shared data and how to use the shared data.

  • Publication number: 20240111784
    Abstract: A data dictionary generation system automatically populates and updates a data dictionary for listings offering shared data. The data listing distribution component distributes the data dictionaries to various remote deployments in a data exchange by using a global messaging framework and replication method. For example, the data listing distribution component replicates a data dictionary generated for the listing and its shared data from a source deployment to one or more destination deployments associated with various geographic regions. The data listing distribution component distributes the listing to the various remote deployments to allow for the listing, including its shared data and data dictionary, to be accessed by users within the geographic region associated with the remote deployment.

  • Publication number: 20240111885
    Abstract: A data dictionary generation system utilizes a background service that is programmed to automatically populate and update a data dictionary for listings offering shared data. A data dictionary includes metadata describing the shared data overall as well as the individual objects included in the listing, such as the individual tables, schemas, views, and functions. To generate the data dictionary, the data dictionary generation system analyzes the shared data to identify objects, identifies a set of data fields associated with each identified object and populates the set of data fields associated with each identified object based on the shared data offered by the listing. To ensure that a data dictionary for each listing remains up to date, the data dictionary generation system periodically scans the listings to identify any changes to share access granted to the listings.

  • Publication number: 20230420268
    Abstract: A method for selectively etching a metal component of a workpiece comprises: forming a hard mask over the metal component; and etching the metal component using an etchant solution, whereby the hard mask controls the etching; wherein the etchant solution is a basic etchant solution; and wherein the workpiece includes a semiconductor component comprising a material of Formula 1: InAsxSb1-x wherein x is in the range 0 to 1. It has surprisingly been found that basic etchants do not damage the semiconductor material. Another aspect provides the use of a basic etchant to etch aluminium selectively in the presence of a semiconductor comprising a material of Formula 1, where x is in the range 0 to 0.25.
