Workflow Database Design

Overview 2.1.1 Why a Workflow Dispatching System A complete data analysis system is usually composed of a large number of task units: shell scripts, java programs, mapreduce programs, hive scripts, etc. There is a time-dependent contextual dependency between task units In order to organize such a complex execution plan well, a workflow scheduling system is needed to schedule execution; for example, we might have a requirement that a business system produce 20G raw data a day and we process it every day, Processing steps are as follows: ...

The scalability of the system is the main reason for promoting the development of NoSQL movement, including distributed system coordination, failover, resource management and many other features. That makes NoSQL sound like a big basket that can be stuffed with anything. Although the NoSQL movement does not bring fundamental technological changes to distributed data processing, it still leads to extensive research and practice on protocols and algorithms. It is through these attempts to gradually summarize some effective database construction methods. In this article, I will focus on the distributed features of the NoSQL database ...

We believe that the goal-oriented design method consists of 4 p, i.e. process, pattern, principles, practices (processes, patterns, principles, practices), and I will discuss the first 3 p. Interaction design is generally a difficult and messy task, and interaction designers are often asked to imagine and define in a tight schedule a possible use of the latest technology, and no one has seen, we must have a deep understanding of the complex areas of products, must balance the competitive priorities, Must understand the constraints of the technology used and the machine ...

The internet has never been a peace, whether in the era of cloud computing or large data era, the Internet world is always undulating, before the advent of cloud computing, Oracle, MSSQL, MySQL, Postgres and other relational databases entrenched data kingdom most of the country, few can shake its position. But now the information is flying in the era changed this situation, with the rapid increase in data traffic ...

The God of the Bible says, there is light, so there is light. We are not God, product design research and development listed sales can not be so easy, can not say I want to have users will bring users. It must be closely combined with the user's own characteristics to meet specific needs. Wanted to talk about how products attract users, later found that the topic is too wide too deep, attract users of the method contains a lot of product life cycle marketing means, nature is not in the designer's concern, so the title changed to chat on-demand design, discuss how the product to meet the different types of users, due to the theory of bias, No patience to read as long as the close ...

Although in some ways almost all applications can be implemented cloud hosting, but there are some specific design and development steps to achieve the optimization of cloud deployment, so as to effectively promote the development of cloud computing. If manufacturers cloud companies want to maximize the benefits of cloud computing, they need to understand the concept of cloud-ready applications, build their cloud-computing infrastructure for a cloud-ready future, and provide convenient services. Cloud readiness means solving the problems caused by the differences between cloud computing. In several important ways, cloud hosting applications or applications running on virtual resources ...
