Hawk principle: Implement common ETL pipeline through IEnumerable

There are already several articles for IEnumerable, this article describes how to use IEnumerable to implement ETL. ETL, an abbreviation of English extract-transform-load, is used to describe the process of extracting data from the source (Extract), transpose (Transform), loading (load) to the destination. Typically, the data

ETL Learning Experience: Exploring the essence of ETL in Key Data Warehouses

As a data warehouse system, ETL is a key link. If it is big, ETL is a data integration solution. If it is small, it is a tool for data dumping. Recall that there have been a lot of data migration and transformation operations over

ETL is a function of three independent data centers linked by a simple programming tool. What does ETL mean?

During database management, extraction, conversion, and loading (ETL, extract, transform, and load) are three independent functions that constitute a simple editing task. First, read the data in the specified source database and extract the required sub-dataset. Then, the conversion function uses rules or drop-down lists to process the acquired data or create con

Data warehouse-ETL

also called a workflow or a task flow. It is more like a workflow. In a workflow, each component is a task. These tasks are executed in a predefined order. You can have branches in the task flow. The execution result of the current task determines which branch to move forward. Data flow is a new concept. Data streams are also called pipelines to solve data conve

ETL Architecture Division test Questions (vii) _ Data analysis

ETL technical support work are briefly described. After the Data Warehouse is on-line, the ETL group needs to provide technical support for the normal operation of the ETL work. Typically, this technical support work is divided into four levels. 1. The first level of technical support is typically a phone support pers

ETL Design in BI project of data extraction, cleaning and transformation

ETL is the process that the data of the business system is loaded into the data warehouse after being extracted and cleaned, the aim is to integrate the scattered, messy and standard data in the enterprise to provide the analysis basis for the decision of the enterprise. ETL

ETL of Data Warehouse--Practical Summary theory

Etl,extraction-transformation-loading abbreviations, Chinese names are data extraction, conversion, and loading. Most warehouse-based data architectures can be summarized as: Data source-->ods (operational datastore)-->DW-->DM (data mart)

The practice of data Warehouse based on Hadoop ecosystem--etl (iii)

predicate is satisfied.Often we also need to connect workflow operations with timed runs, but with different intervals. The output of multiple subsequently running workflows becomes the input for the next workflow. Connecting these workflows together allows the system to refer to it as a conduit for data application. The Oozie Coordinator supports the creation of such a data application

Python Advanced Programming Builder (Generator) and Coroutine (ii): Coroutine and Pipeline (pipeline) and dataflow (Data Flow _

Original works, reproduced please indicate the source: point IIn the first two articles, we covered what is generator and coroutine, and in this article we will describe Coroutine's use of analog pipeline (piping) and control dataflow (data flow).Coroutine can be used to simulate pipeline behavior. by concatenating multiple coroutine together to implement a pipe,
