This article talks about MapReduce (MR) platform with parallel data access. MapReduce is introduced by Google in 2004 for supporting multiple accesses of data. It has been written in many languages such as C++, C#, Java, and even PHP. Famous Social Network Face Book built its massive data warehouse by using the MapReduce technology. The authors also compare the MapReduce technology with database management system (DBMS) “MapReduce complements DBMSs since databases are not designed for extract transform- load tasks, a MapReduce specialty.” Indeed, the combination of MR and DBMS create a powerful of database system. This combination allows big companies to build their database warehouse where they store a lot of information. For example, Face Book store more than 800 million users’ data and information. Google’s data warehouse stores more than 850 TB for supporting user searching. Finally, the authors mention that those technologies are not competition but complementary.
This article mentions data warehouse and database technologies such as MapReduce (MR) and database management system (DBMS). Those technologies are really helpful because they allow people to build massive data warehouses. For instance, Google’s data warehouse like a world library; it support business and study around the world. It also likes the world knowledge. In my work place, every time we have questions we “ask” Google. In school, when I research I also “ask’ Google.
As you know the Jasmine Revolution happened with support of social network like Face Book and Twister. If there are not any database technologies such as MR and DBMS, there is not Face Book or Twister. Therefore, the Jasmine Revolution will not happen. Data warehouse also use to store much important information that supports government, organization, and education. Imagine that, if the government does not have the database, how can it work? The IRS cannot collect tax. The DMV cannot manage vehicles and so on. I think data warehouse is really helpful, and both RM and DBMS are revolution of the database technology.
