Dalberg, President of the Asia Cloud Computing Association in November 2013, said that in 2015 cloud computing would bring 14 million jobs, about 10 million of which are in China. Its push for it innovation is expected to generate 1.1 trillion of dollars in new business revenue each year, and in Europe 2% of GDP is expected to come from cloud computing innovation by 2020. Cloud computing becomes the cornerstone of the IT industry why does cloud computing contribute so much to China's information and communications industry? From the industrial structure, the various parts of it have evolved from the 2010 to gradually connect to a whole ...

Introduction at present, due to the large number of users, massive storage space and strong computing power needs, the traditional customer relationship management model is difficult to meet the current customer relationship management needs; In addition, the application value of cloud computing has been favored by many enterprises, including IBM, Google, Microsoft, Amazon, Yahoo, the company in the cloud computing research has spent a huge amount of human, material and financial resources. Enough to be seen in the value of cloud computing. In order to solve the problems of traditional customer relationship management system, the network application and service related to cloud computing have been applied to customer relationship.

The five major database models, whether relational or non relational, are the realization of some data model. This article will give you a brief introduction of 5 common data models, so that we can trace back to the mysterious world behind the current popular database solutions. 1. The relational model relational model uses records (composed of tuples) for storage, records stored in tables, and tables are defined by the schema. Each column in the table has a name and a type, and all records in the table conform to the table definition. SQL is a specialized query language that provides the appropriate syntax for finding records that meet the criteria, such as ...

Resource scheduling has never been a tempting topic, and it's an inevitable thing to do, and it's generally complex and frustrating for users and makes system administrators feel busy.
