Drupal is a CMS (Content Management System) which can be used, to build websites and applications. Its powerful web serves API allows developers like me to develop a website such as this one KingInfoLife.com. One powerful tool that Drupal offers, is its ability to allow users to not have to write raw SQL statement, to present data on their website.
This tool or module is called Views, which takes care of a lot of the raw SQL statements, developers used to have to write, back in the day. When developers want to create a list of only a certain kind of content, based on certain criteria and requirements defined, by the user, they can use views, to accomplish this task.
Views allow users to select tables from a database, specify the display of the data, use the advanced features to filter content and use HTML as well as CSS to format the output of the data. Developers can use views to build queries and list content, and not have the need to know the database at all, to accomplish these tasks. The criteria for the content can be configured through an administrative interface, to output our data however we like it.
The base table is the first thing we need to select to start building a view, the base table will contain the data that we want to list. Users can select to display information about the nodes created on Drupal, even the comments left from visitors of the website. Once we have selected the base table, then we can proceed to select the display for the content, the options that a user has are: page, blocks, attachments, data exports, and many others, such as embed, entity reference, and RSS feed.
Once the display is selected, then users can select the filter criteria, specify which fields should be used for the display and the order in which the content should be listed. The display will also allow users to select Advanced features, which allow users to add CSS tags, filter content based on current conditions, and even aggregate the content, as well as display certain filters for users. Displays can also be built in a view so that, the displays can share their configurations, with other displays. As a powerful and highly-configurable list maker, views allow users to take data from their websites and display it to users.
Views are divided into several parts such as the display, the format, the fields, the filter criteria, the sort criteria, the contextual fields and it also has relationships. When users want to relate their base table to other content entities, then they can use the relationships features, to display content on their base table, from that related entity.
When users want to display information, based on the URL or dynamic information, they can use contextual filters, to accomplish this task. The best way to learn views and about them is to go ahead and create a view, add a display to that view and add your filter criteria so that you can get a feel for the technology.
