How do humans destroy the ozone layer?
Human activities cause the emission of halogen source gases that contain chlorine and bromine atoms. These emissions into the atmosphere ultimately lead to stratospheric ozone depletion. The source gases that con- tain only carbon, chlorine, and fluorine are called “chlo- rofluorocarbons,” usually abbreviated as CFCs.
Which gases are harmful for ozone layer?
The main substances include chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, carbon tetrachloride, methyl chloroform and methyl bromide. The damage to the ozone layer caused by each of these substances is expressed as their ozone depletion potential (ODP).
What do you mean by ODS?
operational data storeAn operational data store (ODS) is a type of database that’s often used as an interim logical area for a data warehouse. … This is the place where most of the data used in current operation is housed before it’s transferred to the data warehouse for longer term storage or archiving.

What are the three data warehouse models?
In a traditional architecture there are three common data warehouse models: virtual warehouse, data mart, and enterprise data warehouse: A virtual data warehouse is a set of separate databases, which can be queried together, so a user can effectively access all the data as if it was stored in one data warehouse.
What is OLTP system?
An OLTP system is a common data processing system in today’s enterprises. Classic examples of OLTP systems are order entry, retail sales, and financial transaction systems. … These programs, which run in the background while users continue to work on other tasks, may require a large number of data-intensive computations.
Is data lake a relational database?
Another way to think about it is that data lakes are schema-less and more flexible to store relational data from business applications as well as non-relational logs from servers, and places like social media. By contrast, data warehouses rely on a schema and only accept relational data.
