Introduction to ETL technology: Introduction to ETL, data warehouse, and etl Data WarehouseETL is the abbreviation of Extract-Transform-Load. It is used to describe the process of extracting, transforming, and loading data from the source to the target. ETL is commonly used in data warehouses, but its objects are not l

ETL TL, short for extraction-transformation-loading. The Chinese name is data extraction, conversion, and loading. ETL tools include: owb (Oracle warehouse builder), Odi (Oracle data integrator), informatic powercenter, aicloudetl, datastage, repository explorer, beeload, kettle, dataspider ETL extracts data from distributed and heterogeneous data sources, suc

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 the past few years. However, the work is basically a one-time job or a small amount of data. You can use access, DTS, or compile a small program on your own. However, in the data

ETL scheduling development (1) -- writing instructions, etl Scheduling Preface: During database operation and maintenance, files are often transferred between systems to perform operations such as data extraction, conversion, and integration. In addition, statistical scheduling is performed after data integration. Here, I will describe an ETL scheduling developed

ETL scheduling development (5) -- connect to the database to execute database command subroutines and etl Scheduling In ETL scheduling, you need to connect to the database to read and write data. The following subprograms use the input database connection string and database commands (or SQL) to perform the required operations: #!/usr/bin/bash#created by lubinsu

The neo4j being used is the current latest version: 3.1.0, various tread pits. Say how to use the Chinese index in neo4j 3.1.0. Choose the Ikanalyzer to do the word breaker. 1. First refer to the article: https://segmentfault.com/a/1190000005665612 The way of indexing with Ikanalyzer is roughly spoken. But it is not clear, in fact, the background of this article is to use embedded

You can also import data from a relatio

ETL (extract-transform-load abbreviation, that is, data extraction, transformation, loading process), for enterprise or industry applications, we often encounter a variety of data processing, conversion, migration, so understand and master the use of an ETL tool, essential, Here I introduce a I used in the work of 3 years of ETL tools kettle, the spirit of good t

https://www.ibm.com/developerworks/cn/java/j-lo-neo4j/NEO4J is a high-performance NoSQL graphics database. NEO4J uses graph-related concepts to describe data models, saving data as nodes in diagrams and relationships between nodes. The relationship between data in many applications can be modeled directly using the concept of nodes and relationships in the diagra

Etl tool, kettle implementation loop, etl Tool kettle implementation Kettle is an open-source ETL Tool written in java. It can be run on Windows, Linux, and Unix. It does not need to be installed green, and data extraction is efficient and stable. Business Model: there is a large data storage table in the relational database, which is designed as a parity datab

neo4j Introduction Graph database Requirements  can be clearly intuitive way to store the graph data, rather than distort the change for other alternative way  can simply map operations, such as search, traversal, etc. The basic idea of the graph database (graph) is composed of nodes (node, vertex) and relation (relationship, edge) to record data on nodes (properties of nodes, property)  nodes are organized into graphs by the relationship, and the

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 connections with other data, so that it can be converted to the desired state. Finally, we us

For the Data warehouse and ETL knowledge, I am basically a layman. Everything has to start from scratch, take a note, to facilitate the understanding of learning progress.First, let's take a look at the basic definition:Well, some people also called the ETL simple data extraction. At least before the study, the leader told me that you need to do a data extraction tool.In fact, extraction is the key part of

understand the relationship is the key to correct use of the graphical database.Note: The node set here is my own translation. In the NEO4J official document, it is called a label. The original is: A label was a named graph construct that was used to group nodes into sets; All nodes labeled with the same label belongs to the same set. I personally feel that the blunt name label is easy to confuse others, so chose the "group nodes into sets" of the fr

Create a Neo4j Cluster Environment Introduction: Neo4j is currently the mainstream graph database. It also provides highly available cluster solutions. This article will try to build a highly available Neo4j environment. 1. What is graph database?
