While a lot of databases have been created listing information in a table format, the web isn't set up in a tabular style. Neither is plenty of data in a variety of formats that the web uses. However, many databases are still using tables, because many web developers feel that tables handle plenty of data better than any other structure.
Others feel that the data tables known as RDB should be converted to RDF, a format used to gather an even wider array of metadata across the worldwide web. The ability to convert to RDF will be extremely beneficial as technology advances to Artificial Intelligence AI and beyond.
