Therefore, enterprises still do not maximize the use of existing data resources, which wastes more time and money and loses the best chance to make key business decisions. Therefore, how can enterprises accessUsing various technical means and converting data into information and knowledge has become the main bottleneck for improving its core competitiveness. ETL is a

Transwarp Data Hub integrates Data integration/ETL, big Data storage and online service systems, memory-based efficient computing engines, high-performance SQL, statistical analysis, and machine learning, achieving Performance breakthroughs. In Sun yuanhao's words, Transwarp Data Hub has a "lightning" speed, which is 10-10 faster than the open-source Hadoop 2.0 ~ 100 times. In addition, Transwarp Data Hub has powerful analysis capabilities and is fully c

such as a Kafka log. Batch processing becomes a recording system, and the data stream is processed in real time to create a three-tier structure: A view, an index, a service, or a data mart.Similar to the flow layer of the lambda (lambda) framework, there is no batch layer. Obviously this requires the message layer to store and supply massive amounts of data, and has a powerful and efficient stream processor to handle this process.There is no free lunch, the problem is very difficult, streaming

cheaper than the primary storage. Conversely, poor caching can introduce a considerable amount of extra overhead that can hamper usability. I've never seen a system that doesn't have a chance to get the cache going, and the key is to find the appropriate caching strategy based on the situation. Summary
Scalability is sometimes called "non-functional requirements," meaning it has nothing to do with functionality and is less important. That's a mistake to say. My view is that scalability is a pre

Data mining uses historical data analysis to predict customer behavior. In fact, the customer may not know what to do next. Therefore, the results of data mining are not as mysterious as people think. It cannot be completely correct. The customer's behavior is related to the social environment, so data mining is also affected by the social background.

the data source, cleans the data, and finally loads the data to the data warehouse according to the pre-defined data warehouse model.Therefore, how enterprises use various technical means and convert data into information and knowledge has become the main bottleneck for improving their core competitiveness. ETL is a major technical means.
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.

Because both of them are used, informatica is easy to manage in the future, especially for data correction. when data is supplemented in the later stage, the data stream is clear at a glance.SQL is efficient, but it is inconvenient to maintain it later. It takes a long time to find a data stream ..ETL tools are easier to manage and maintain, especially complicated cleaning processes.
ETL tools are suitable for fixed and stable processe
