What kind of virtual currency is DAAS
1.1
Data
data is the physical symbol of load or record information arranged and combined according to certain rules. It can be numbers, words, images, sounds, computer code and so on
the meaning of data is to transmit information. The reception of information begins with the reception of data, and the acquisition of information can only be achieved through the interpretation of data background. Data background is the information preparation of the receiver for specific data, that is, when the receiver understands the law of physical symbol sequence and the directional target or meaning of each symbol and symbol combination, he can obtain the information loaded by a group of data. In other words, data can be transformed into information, which can be expressed by the formula "data + background = information"
1.2
Service
service is a kind of paid or free activity that works for others and benefits others. To meet the special needs of others in the form of providing living labor instead of in kind
service provision can involve: activities completed on tangible procts provided by customers (such as repaired automobiles); Activities performed on intangible procts provided by customers (e.g. income statements required to prepare tax returns); The delivery of intangible procts (such as the provision of knowledge transfer information); Create an atmosphere for customers (e.g. in hotels and restaurants)
1.3
data as a service
as a kind of service, data is realized through the activities of transferring useful information to help others
for example, the data about the composition and damage of the car can help the repairman to repair. We often search for information on the Internet, and the useful information in the information has an impact on our activities, which is also a kind of service.
PAAS, platform as a service. For example, Netease has an instant messaging service interface
DAAS is a desktop as a service, such as Amazon's desktop service
SaaS, software as a service, such as Evernote and salesforce.
DAAS, a digital audio analysis system, is a PC based test system, supporting dos and windows operating systems. DAAS is a data-as-a-service, which is a new service concept after IAAs, PAAS and SaaS
Through the centralized management of resources, data as a service points out the direction for improving it efficiency and system performance. Therefore, DAAS has been favored by many CIOs in the past few years. Its main technologies include data virtualization, data integration, SOA, BPM and PAASDAAS can adjust the scale of computing resources to meet the changing needs. The DAAS provider provides a multi tenant model, so it can use the computing resources in the resource pool or return the resources at almost no cost. No impact on end users. With proper management of user settings and content, users can be seamlessly migrated to the newly deployed VM

advantages of DAAS
1. Agility through the integration of data access, customers can move it more quickly without considering the source of underlying data. If customers need a slightly different data structure or call data from a specific location, DAAS can quickly meet the needs with minimal changes
2. Cost effective service providers can find data experts to build the underlying architecture, and the presentation layer can be outsourced to others (reports, dashboards, user interfaces, etc.), At the same time, any change requirements can be more flexible to meet
3. Data quality controls data access through services, which is very helpful for data quality improvement, because there is only one update point. After the service is thoroughly tested, if the next deployment does not change, then they only need to carry out regression test
4. The advantages of efficiency, high availability and flexibility come from virtualization. Physical server resource sharing will improve efficiency, and cluster across multiple physical servers can improve availability, Dynamic adjustment and real-time migration of cluster nodes to different physical servers can enhance the flexibility
