speed requirement for data collection, processing, and use is the second challenge. When the data volume reaches the TB or PB level, traditional algorithms that process small amounts of data cannot process large datasets quickly and effectively enough. Both storage media and management analysis have been greatly challenged.Any single product cannot solve big data problemsThe advent of big data has become a top priority for enterprise development, and many IT giants have joined the ranks of big

Today, massive volumes of information are filled with the IT world. data shows that in the next decade, data and content around the world will increase by 44, 80% of which are unstructured data. The advent of the big data era brings challenges and opportunities to enterprises. Many IT giants have joined the ranks of big data and launched their own big data products, such as sap hana, Vertica acquired by HP, InfoSphere BigInsight of IBM, and Big Data A

Having been concerned about SSIS performance issues with SQL Server 2005, one of my fellow testers tested it for reference. There is a part of the project data migration work, frankly, from the old system to switch data in the new system model, the old system data sources are more complex and diverse, the new nature is Oracle9.2. This is a one-time job, with SQL naturally is the fastest way, whether it is the speed of development or data transfer. But party a must see the interface, hope this

These years, almost all work with ETL, have been exposed to a variety of ETL tools. These tools are now organized to share with you. An ETL Tool Foreign 1.

) The PROC Program (merging and conversion) provides corresponding interfaces for the merging and conversion processes and scheduling to schedule the oracle proc program.4) Stored Procedure (conversion): encapsulates the stored procedure in the PROC program for scheduling.5) DataStage (PI processing), the scheduling system provides interfaces with DataStage to schedule various types of

Label:At present, Teradata Data Warehouse ETL operation using ELT mode, because the loading is too heavy, the need to transfer the ETL pressure to a dedicated ETL server. For ETL tools, there are already mature commercial/open source tools in the market, such as Informatica's PowerCenter, IBM DataStage, and open source kettle.Here are some of my own thoughts, the starting point is, how to spend a relatively small price to switch the ELT mode to ETL mo

By significantly accelerating queries and enhancing data compression, You can significantly reduce storage costs and create time-aware tables within one hour. This is all possible in the latest version of IBMDB2. Together with many other improvements, the above improvements make IBMDB210 and InfoSphereWarehouse10 a more powerful, more economical, and more reliable transaction processing and With significantly accelerated queries and enhanced data compression, You can significantly reduce storage

profiling API. For example, the YouTube Analytics API provides programming clients with statistics such as the number of views and favorite times (number of likes). As a result, more business applications can interact with social media through visual and programmatic interfaces. For companies of all sizes, the next challenge is to apply large numbers of social data to the business most effectively through big data analysis. Data visualization (an integral part of the entire analysis scenario) i

The data warehouse has encountered several problems recently, which are summarized as follows. 1. Migration from mysql to oracle. This is a complicated problem, because we have no plans to invest in an ETL tool such as datastage, so at first I decided to write my own code and import mysql Data into the text, use sqlldr to import data to oracle. This process is not very complicated, but it is annoying because I encountered the following problems: 1.1 N
