Ensuring WCAG Compliance in SQL Server Queries for Accessibility Features
I've tried everything I can think of but I'm not sure how to approach While reviewing the SQL queries for a project aimed at enhancing accessibility, I need to ensure that our data retrieval methods align with WCAG standards. Specifically, we want to implement features that support screen readers and provide alternative text for images stored in our SQL Server database. Currently, the application uses the following basic query to pull image data for display: ```sql SELECT ImageID, ImageURL FROM Images WHERE IsActive = 1; ``` However, to meet accessibility guidelines, I need to include additional fields for alternative text descriptions. I tried extending the query, but the performance dropped significantly when multiple joins were added: ```sql SELECT i.ImageID, i.ImageURL, a.AltText FROM Images i JOIN AltText a ON i.ImageID = a.ImageID WHERE i.IsActive = 1; ``` This query includes a join to an `AltText` table, which contains the necessary descriptions for accessibility. The problem arises when the `AltText` table grows larger. I've experimented with indexing the `ImageID` in both tables, but the response time is still not meeting user expectations. Additionally, I’m looking for best practices to ensure that the data returned is appropriately structured for screen readers. For instance, is it better to return JSON objects instead of flat queries? Here’s how I tried formatting it: ```sql SELECT JSON_QUERY( (SELECT i.ImageID, i.ImageURL, a.AltText FROM Images i JOIN AltText a ON i.ImageID = a.ImageID WHERE i.IsActive = 1 FOR JSON PATH)) AS ImageData; ``` This approach produces a nested JSON output, but I’m concerned about its readability and how it integrates with our C# backend, which serves the frontend application. Any advice on optimizing these queries for accessibility or confirming that our approach aligns with WCAG standards would be greatly appreciated. The project is a desktop app built with Sql. I'd be grateful for any help. I recently upgraded to Sql 3.11. Any ideas what could be causing this?
