The big data is "soar" in 2012, and it will change every aspect of data management in a dramatic way. Large data systems have brought changes to machine-generated data management, continuous ETL, operational bi, Dynamic Data, and cloud-based data warehouses. With big data coming into the 2013, there is no technology that is more active than the NoSQL database and Hadoop, and they all have greater room for improvement. According to a report marketanalysis.com 2012, it's just Hadoop mapr ...

The database server is actually the foundation of every electronic transaction, financial and enterprise resource Planning (ERP) system, and it often includes sensitive information from business partners and customers. Although the data integrity and security of these systems are important, the level of security checks taken against the database is not as high as the security measures of the operating system and the network. Many factors can disrupt data integrity and lead to illegal access, including complexity, poor password security, misconfigured, undetected system backdoor, and mandatory routine use of adaptive database security methods ...

IDC predicts that large data will increase structured and unstructured data at a rate of 60% per annum. Industries need to be well prepared for these new data, and the traditional database has been the answer to this question. However, through cloud technology, vendors have introduced more ways to host these databases in the public cloud; cloud service providers provide a range of services that allow users to easily complete database extensions, freeing users from cumbersome database hardware customizations. Jeff Kelly, an expert in Wikibon, a big data research firm, said: "Given the trend of big data, ...

The IT world is rapidly embracing "big data". Large data storage will be the next topic of discussion for Big data analysis, as big data is getting bigger, for example, and startups are using these systems to analyze the history of human evolution with trillions of DNA tests. Although large data (and its underlying technology NoSQL) is becoming a popular language in information systems, there is not much discussion about the security implications of large data. Large data Overview NoSQL refers to the relational database, which contains a large number of different types of structured data and unstructured data storage ...

After Facebook abandoned Cassandra, HBase 0.89 was given a lot of stability optimizations to make it truly an industrial-grade, structured data storage retrieval system. Facebook's Puma, Titan, ODS time Series monitoring system uses hbase as a back-end data storage System. 　　HBase is also used in some projects of domestic companies. HBase subordinate to the Hadoop ecosystem, from the beginning of the design of the system is very focused on the expansion of the dynamic expansion of the cluster, load are ...

The Hadoop system runs on a compute cluster of commodity business servers that provide large-scale parallel computing resources while providing large-scale distributed data storage resources.

It can be said that big data is one of the hottest trends in the IT industry today, and it has spawned a new batch of technologies to deal with big data. And new technologies have brought the latest buzz words: acronyms, professional terms, and product names. Even the phrase "big data" itself makes a person dizzy. When many people hear "big data", they think it means "a lot of data", and the meaning of large data does not only involve the amount of data. Here are a few popular words that we think you should be familiar with, sorted alphabetically. ACID ...

This is my second time for the new project in-depth research NoSQL, but also the second decision to give up NoSQL. 　　Like the conclusion I made last time about why I chose to use nosql so hard, we finally decided to give up NoSQL and use a traditional relational database. I've come up with a lot of comments from the last post to evaluate NoSQL-the core of the solution is "depending on your needs." But despite the need for clarity, it still takes time to research and find out whether a particular NoSQL engine is exactly what you need. There are so many ways that you can't ...
