Data is the most important asset of an enterprise. The mining of data value has always been the source of innovation of enterprise application, technology, architecture and service. After ten years of technical development, the core data processing of the enterprise is divided into two modules: the relational database (RDBMS), mainly used to solve the transaction transaction problem; Based on analytical Data Warehouse, mainly solves the problem of data integration analysis, and when it is necessary to analyze several TB or more than 10 TB data, Most enterprises use MPP database architecture. This is appropriate in the traditional field of application. But in recent years, with the internet ...
After MySQL was acquired by Oracle, the industry has never stopped talking about the Open-source database, and the voice of PostgreSQL will be replaced as the most popular Open-source database. However, from the Db-engines rankings, the gap between PostgreSQL and MySQL is far more than "a few floors" so high (Postgresq not score a fraction of MySQL). Looking at the entire list of 193 databases, we will find that the NoSQL database has accounted for most of the land, the listed traditional relational data ...

The document database of NoSQL database technical characteristics Today's cloud computing practitioners are not unfamiliar with the term nosql, though many technicians have long been working on relational databases, but now they are looking forward to nosql technology. The transition from relational to NoSQL databases is definitely a big change to be considered for businesses. This involves not only the changes in software, but also the conceptual changes in data storage. Most non-relational databases have fast and scalable features. By discarding relational storage models and schemas, relationships ...
Cloud computing--at least as an extension of virtualization--has become increasingly widespread. However, cloud computing does not yet support a complex enterprise environment. So the cloud computing architecture is clear, and experience suggests that before cloud computing matures, we should focus on the details of the system's cloud computing architecture. Based on some existing cloud computing products analysis and personal experience, summed up a set of cloud computing architecture, cloud computing architecture can be divided into four layers. Cloud computing architecture--the display layer is primarily used to show users what they want in a friendly way, and it takes advantage of the middleware layer below ...

Cloud computing not only changes the way information is provided ...
Now Apache Hadoop has become the driving force behind the development of the big data industry. Techniques such as hive and pig are often mentioned, but they all have functions and why they need strange names (such as Oozie,zookeeper, Flume). Hadoop has brought in cheap processing of large data (large data volumes are usually 10-100GB or more, with a variety of data types, including structured, unstructured, etc.) capabilities. But what's the difference? Today's enterprise data warehouses and relational databases are good at dealing with ...
Large data as a concept in the IT field has been recognized by many people. As in many aspects of the IT field, new technologies were first used by large enterprises, and then in the late stages of the entire use curve, small and medium enterprises began to use it. Big data seems to have gone through the same process. As large data continues to evolve in the real world, it is gradually being applied to less large data elements. Most standards consider smaller datasets being handled by large data tools in a way that is specific to large data architectures. Still, there is a consensus that there will be more data, not less, in the future.
