The trend of ETL and ELT products viewed from Oracle acquisition sunopsisDate:2008-6-17 Source:amteam I want to comment Big| Medium |Small Submission Print Introduction: This article mainly from Oracle Acquisition sunopsis analysis of ETL and ELT products trends and explain that the ELT tools than ETL tools can handle large data volume more effi

Different map service platforms have diverse requirements on map file formats, and files used by ArcGIS are difficult to be used on other platforms, therefore, a format conversion service is required to overcome the trouble of using different platforms. The following uses the conversion from TIFF format to geotiff format as an example.First, you need to prepare several items:1. Make sure that ArcGIS data interoperability for desktop is installed.2. Check data interoperability in the extended mod

Ods-bi in the construction of ETL to occupy 1/3 of the time, deep feelings. The modeling of BI, from the physical data layer, the logical data layer, the business logic layer at all levels, there are many automated tools to handle.However, the process in ETL must be designed according to the performance. Summarize the next few parts.1. Data source/Data target managementTo determine the table, file, or restf

In the data warehouse project, ETL is undoubtedly the most tedious, time-consuming, and unstable. If the data source and target are both Oracle and meet certain conditions, you can use the oracle tablespace to improve ETL efficiency.To use a tablespace, the following conditions must be met:The source and target databases must both be larger than 8i;Ø for versions earlier than 10 Gb, the source and target da

ETL is responsible for the scattered, heterogeneous data sources such as relational data, flat data files, such as the extraction of the temporary middle layer after the cleaning, transformation, integration, and finally loaded into the data warehouse or data mart, as the basis for online analysis processing, data mining. The term ETL often appears in the Data warehouse, but its object is not confined to th

During the three-day holiday on May Day, some ETL logic problems occurred, resulting in the daily incremental data to be loaded into DW is not loaded as designed. Therefore, you need to check the generated incremental data after ETL to avoid the problem of passive processing when the incremental data is lost one day. Requirement: if there is a problem with the incremental data of

What does the ETL data conversion system bring to customers?With the development of society and computer technology, people began to reprocess the data in the original database to form a comprehensive and analysis-oriented environment to support the emergence of scientific decision-making. As a result, the ideas, technologies, and products of data warehouses are gradually formed. The purpose of building a data warehouse is to establish a systematic da

ETLIs the abbreviation of extract-transform-load. It is used to describe the process from the source end to extract (extract), transpose (Transform), load (load) to the target end.ETLThe term is commonly used in data warehouses, but its objects are not limited to data warehouses.

The scripts submitted to production must be commit to the svn server. 3) The directory on lunix reflects the directory ing to svn. Background2: There are many areas in the script, such as the range, indicator, and parameter value. How can we make these operations more flexible, instead of writing them to death? Solution: 1) map Chinese or English to numbers as much as possible, saving storage

First, the purposeMerge tables on different servers onto another server. For example, merge table B on server 1 on table A and server 2 to table C on server 3Requirements: Table A needs to be cropped (removing unnecessary fields), table B needs to add some fieldsIi. Methods of Use(1) Create a new Table C (field that conforms to the actual system design) in the database on server 3(2) Create a new table input, connect to server 1, select the table you

Introduction to the outsetToday, when you load data using QV, you run into some state in the column, and the information is separated by a symbol, which is not conducive to data analysis because the content in the string is itself a dimension. Search the Internet to find a solution to the method, record.For example, in the first picture, s200,m250,r35 are all Invoice types, which need to be taken out as the dimension DIMENSION of the analysis.You can

Microsoft integration services is a platform that can generate high-performance data integration solutions, including extracting, transforming, and loading (ETL) packages for data warehouses. Integration Services includes graphical tools and wizard used to generate and adjust packages; tasks used to execute workflow functions (such as FTP operations), execute SQL statements, and send emails; the data sources and targets used to extract and load data.
