Types Of Databases Management Systems

In the data center lifecycle, data center operation and Management is the last and longest period in the data center life cycle. Data center operation and Maintenance management is: In order to provide information system services to meet the requirements, and the information system services related to the data center of the various management objects of the planning, organization, coordination and control, is the information system services related to all management work. 　　 Data center operation and maintenance management mainly shoulder the following important goals: compliance, availability, economy, service and other four goals. ...

"The role of data storage is changing, one of the factors is that data is becoming more and more complex, and for a data storage system designed 5-10 years ago, it must be able to handle the diversity of resources," said Donald Feinberg, the analyst's Vice president Complexity, large capacity, and system response speed to real-time and other characteristics. And he argues that while big data has different meanings for different industries, basically large data represents large, complex, unstructured data. However, for good at dealing with knots ...

As data centers, Grid computing, supercomputing, cloud computing and other technologies and concepts rise, IT industry is also moving towards business model, technology architecture to management operations and other aspects of the direction of change. At the same time, cloud management technology has gradually entered our vision, the topic of cloud management also more and more hot. In terms of user requirements, technical features and functional composition, cloud management is mainly the management of data centers. The management focuses on the integration of key resources and business, visualization and virtualization, while Cloud management focuses on the allocation of resources on demand and the charging operation of the cloud.

Enterprises in the process of information often use a number of systems such as enterprise resource planning (Enterprise Resource planing,erp), Customer relationship management (customers relationship MANAGEMENT,CRM), etc. The database data used by these systems are independent, which increases the difficulty of managing costs and maintenance. Private cloud and database consolidation can reduce system costs and complexity, improve flexibility and quality of service; Private cloud can be implemented for servers, storage, applications, or IT services ...

Companies are moving more data to cloud computing than ever before, covering many different types of service patterns. As the sensitivity and importance of moving into cloud computing data grows, security experts are actively seeking to use cryptography to protect such data, and the technology they use is the technology that they have been using and trusted for years in their data centers.   　　However, in some cases, this goal is not easy to implement, or you need to use a number of different methods and tools, especially for encryption key management. In this article, we will explore the current ...

Cloud management is increasingly well known and is becoming a hot topic for now, with every emerging company and established vendors providing some tools to manage the cloud environment. There are a wide variety of tasks, such as monitoring tools, configuration tools, and tools in between. On the market there are natural fog (vaporware), this kind of tools to dazzle people, want to quickly have a certain understanding and clear, it is not easy. If you deploy a cloud that is not a mission-critical environment, but rather a fairly static environment, you may not need to configure the system dynamically. In the ...

Cloud Management is a hot topic, and it is popular that every start-up and established vendors provide some tools to manage the cloud environment. There are monitoring tools, configuration tools, and tools in between. There are naturally foggy pieces on the market (vaporware), and it is not easy to get a clear idea. If you deploy a cloud that is fairly static or not a mission-critical environment, you may not need to configure the system dynamically. In this case, the product's built-in standard tools for adding/changing/removing resources may be more than sufficient. Several vendors have products designed specifically for cloud computing management (...).

"IT168" I have always felt that nosql in fact very easy to understand, I have also had a very in-depth study of NoSQL, but in the recent preparation of yuntable chart, found that NoSQL not only very profound, 　　And my personal understanding of NoSQL is only superficial, but I am still a "shame and then Yong" people, so after a period of study, from the sixth part of this series, will talk to you nosql, and this article will be the main to do a NoSQL database review. ...

Traditional data storage and management are based on structured data, so relational database systems (RDBMS) can meet the needs of various applications.

The storage system is the core infrastructure of the IT environment in the data center, and it is the final carrier of data access. Storage in cloud computing, virtualization, large data and other related technologies have undergone a huge change, block storage, file storage, object storage support for a variety of data types of reading; Centralized storage is no longer the mainstream storage architecture of data center, storage access of massive data, need extensibility, 　　Highly scalable distributed storage architecture. In the new IT development process, data center construction has entered the era of cloud computing, enterprise IT storage environment can not be simple ...
