etl flow chart

1. Data Flow Diagram) Adhere to DFD, which expresses the system's logical functions in graphical form from the perspective of data transmission and processing. The logical flow of data within the system and the logical Exchange Process, is the main expression tool of the structured system analysis method and a graphical amplification used to represent the software model. It is a transformation that depicts

A business flow chart is a chart that describes the business relationship, operation sequence, and management information flow between units and personnel in the system. It helps analysts find out the non-Confluence direction in the business flow, it is a physical model.The

When I started to build a data center charging system, master and I said that we had to analyze the requirements before doing the system. Only by clarifying the requirements can we start the project. So let's look at it first, but I haven't seen it for a long time. Later, master said that the first part of the data room charging system is the database. This makes me even more confused. I don't even know how the database can be created, because I don't know how the information flows. In addition,

Many of the concepts in the UI design do not appear to be very different, but in fact they are very diverse. @akane_lee, a Taiwanese designer who has not issued a paper for a long time, has elaborated the function of flow Chart and UI flow by discriminating the concept of opportunity. Nearly one months without a dispatch, busy writing planning cases, do Prototyp

receipt. The system must also be equipped with a settlement system that transfers the final menus and consumption prices to the settlement front-end, allowing the cashier to perform operations quickly. This system will eventually need to be presented. How can we design the interface of the handheld terminal? Can a waiter order a single dish with less clicks? How to Design the settlement center interface? Through the above story, do you better understand the relationship from strategy, tactics,

Each data store has a name.External entity: An external entity is a person or organization that exists outside the software system, and he points to the origin of the data or the data that the system produces.External solid proce

In the past years of soft examination in the afternoon, there are five big questions, respectively, is the design of data flow chart, database design, UML diagram, algorithm and design patterns, starting from today's blog, small series with you to study the afternoon of soft exam related content, including theoretical knowledge and typical examples of the explanation, Hope to give the necessary small partne

The drawing of the flow chart (turn) Streaming Diagram (DFD)The data flow diagram, or DFD, is a tool used in the SA method to represent the logical model of the system, which graphically depicts the process of flowing and processing in the system, because it only reflects the logic functions that the system must complete, so it is a functional model.The figure be

point and the style of the attachment. Without calling the Addendpoint method sequentially, the element will have one more line of nodes above it. For the meaning of each parameter in Hollowcircle, you can view the API. There is one more place to see: Jsplumb.repainteverything (); the literal meaning can probably know what this sentence is to do, fix all. When you drag an element in the middle area, the node does not move along with the element without this phrase. After that, the node will f

basic elements of the streaming diagram:Why use a streaming diagram? because flow graphs represent the flow and processing of class data in the system. The streaming diagram is a tool used in structured analysis, and it is a functional model because it only reflects the logical functions that the system must complete. and users and developers to communicate with the use of data

prototypes, so it doesn't need to be too fine. Review is very important. In addition to whether the process itself is correct, it is also necessary to consider whether the existing is the best solution, if some of the steps can be simplified. The evaluation of a system design is good or bad, not to see the normal logic, but to see the exception branch processing. For example, online shopping, the payment has not been successful but the bank card money has been deducted, then need to design a

Article Description: prepare a control flow chart to provide a guidance note when you may be involved in the project process. Of course, this is a few days to watch other projects when the summary, and then according to the company's current department and team configuration design. Perhaps with the further understanding of the future, the idea will change, it should be said that will change. Pre

I have been working as a portal and have never had the opportunity to access the warehouse website, such as B2C. So I want to find an article about the order process. Today I just found one and marked it, look back The soul of the B2C system is the order process. The following shows the two most important dynamic diagrams of the order, one of which is the order process activity diagram. There is also a simple order status chart. You can use these two
