All developers also need skills related to the industry in which they are going to work. For instance, those working in a bank should have knowledge of finance so that they can deployment models in cloud understand a bank’s computing needs and construct data warehousing solutions that match those needs. In the last stage, data is loaded into the target warehouse database.
That’s challenging because a massive volume of data needs to be loaded in a relatively short period. Recover mechanisms and load verifications are applied before the entire process starts, to ensure that everything happens smoothly.
