ETL ConsiderationsAs a data warehouse system, ETL is the key link. Said Big, ETL is a data integration solution, said small, is to pour data tools. Recall the work over the years, the processing of data migration, conversion is really a lot of work. But those jobs are basically a one-time job or a small amount of data, using Access, DTS, or making a small program

BI Architecture-bi Key Links ETL related knowledge Main function: Load the data of the source system into the Data Warehouse and data mart layer; The main problem is the complex source data environment, including a wide variety of data types, huge load data volumes, intricate data relationships, and uneven data quality common terminology etl: Data extraction, conversion, loading (extract/ Transform/l

Assembly Area Preparing data, often also called data management, refers to acquiring data and translating it into information, and ultimately submitting that information to the front-end query interface. The background does not provide query services, the Data Warehouse methodology assumes that data access in the background is strictly forbidden, which is the sole purpose of the foreground. The backend part of the data warehouse is often referred to as the staging area (Stagingarea). Data aggreg

ETL: Abbreviation of extraction-transformation-loading. The Chinese name is data.Extract, convert, and load data. ETL extracts data from distributed and heterogeneous data sources, such as relational data and flat data files, to a temporary middle layer for cleaning, conversion, integration, and finally loading data to a data warehouse or data warehouse.Data mart has become the basis for Online Analytical P

ETL is the process that the data of business system is pumped into the data warehouse after being cleaned and transformed, the purpose is to integrate the data of the enterprise in the scattered, messy and standard, and provide the analysis basis for the enterprise's decision. ETL is an important part of BI project. Typically, in BI projects, ETL spends at least

ETL is the process of data extraction (Extract), Transformation (Transform), loading (load). It is an important part of building data Warehouse. Data Warehouse is a theme-oriented, integrated, stable and constantly changing data collection to support the decision making process in the management. There may be a large number of noise data in the Data Warehouse system, and the main causes are: misuse of abbreviations, idioms, data entry errors, duplicat

ETL is an important part of Bi. Let's take a look at the definition in wiki: ETL is the abbreviation of extract-transform-load. It is the process of data extraction, conversion, and loading for filling and updating data warehouses. This is the data collection step before realizing business intelligence. After this step is completed, you can mine and analyze the data in the database. For

The data increment extraction mechanism in ETL( Incremental extraction is an important consideration in the implementation of Data Warehouse ETL (extraction,transformation,loading, data extraction, transformation and loading). In ETL process, the efficiency and feasibility of incremental updating is one of the key problems of

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 too

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 person, which is a Technical support services win

ETL design and consideration in Bi Projects ETL is a process of extracting, cleaning, and transforming data from a business system and loading it into a data warehouse. It aims to integrate scattered, disorderly, and standardized data in an enterprise, it provides an analysis basis for enterprise decision-making. ETL is an important part of Bi projects. In bi p

ETL concepts The three ETL letters represent extract, transform, and load, namely, extraction, conversion, and loading. (1) Data Extraction: extract the data required by the target data source system from the source data source system; (2) Data Conversion: Convert the data obtained from the source data source into the form required by the target data source according to business requirements, and clean and
