Street Art View is one of these.ДЄs you can guess by its name, this is a site that will let you see street art from all over the world via a Google Map that can be used in all the habitual ways. Still, sites that put Google Streetview to imaginative uses are slowly beginning to materialize.

The lack of built in mechanism to update such a view leaves developers vulnerable to risky homegrown alternatives to a core database service that should have been part of the materialized view feature. If you think about it, the uses such technology can have go well beyond all these things we used to see in sci-fi movies when we were children. Introduction of materialized view in mongodb helps to speed up certain queries that needs costly joins across collections. When a master table is modified, the related materialized view becomes stale and a refresh is necessary to have the materialized view up to date.

Google Streetview is a really neat platform, but we are yet to see applications that truly maximize it. In contrary of views, materialized views avoid executing the SQL query for every access by storing the result set of the query. Data is generated by a simulator and written directly to Cosmos DB. The sample data simulates an IoT environment, even though, as said before, the Materialize View pattern can be applied to any scenario and industry. When that happens, the data in the materialized view needs to be updated. These tables can have their data updated, inserted, or deleted. The data thatвЂ™s used to populate the materialized view is stored in the database tables.
