This article will introduce big SQL, which answers many common questions about this IBM technology that users of relational DBMS have. Large data: It is useful for IT professionals who analyze and manage information. But it's hard for some professionals to understand how to use large data, because Apache Hadoop, one of the most popular big data platforms, has brought a lot of new technology, including the newer query and scripting languages. Big SQL is IBM's Hadoop based platform Infosphere Biginsight ...

The necessity of database encryption large database management system platform is typically Windows NT and Unix, these operating system security level is usually C1, C2 level. They have user registration, user identification, Arbitrary access control (DAC), audit and other security functions. Although the DBMS on the basis of the OS added a number of security measures, such as access control based on permissions, but the OS and DBMS on the database file itself is still lack of effective protection measures, experienced online hackers will "bypass", directly using the OS tools to steal or tamper with the database files ...

For all applications around cloud computing, the current application of public cloud services represents only a fraction of total IT spending. This will not change unless key mission applications, which account for the bulk of the corporate budget, move to the public cloud. The biggest bottleneck in public cloud applications seems to be the high cost of cloud storage. Web-related cloud applications may store hundreds of megabytes of data, while mission-critical applications may store terabytes of data, which, at current prices, are more expensive to store than most users can afford. But thankfully, we have two strategies to ...

The REST service can help developers to provide services to end users with a simple and unified interface. However, in the application scenario of data analysis, some mature data analysis tools (such as Tableau, Excel, etc.) require the user to provide an ODBC data source, in which case the REST service does not meet the user's need for data usage. This article provides a detailed overview of how to develop a custom ODBC driver based on the existing rest service from an implementation perspective. The article focuses on the introduction of ODBC ...

In the past few years, the rise of social media, the large number of applications of digital sensors and the widespread proliferation of mobile devices have led to the rapid generation of massive amounts of data. At the same time, how to get the useful value of large data becomes the key of firm decision. In this article, the author brings the Big Data solution for SAP, but asks for the proposal. SAP large Data solution is mainly focused on the database and data Warehouse level and enterprise information management level. Among them, the data warehouse and Data Warehouse solution mainly by the real-time data platform Hana, analysis type database ...

Two days ago, someone asked questions on Weibo, in what way to tell the big data and cloud computing can not be heard by professionals more clearly, in fact, there are many cases of large data, business intelligence analysis has repeatedly mentioned the value and significance of data mining, but today to see more data than before, big data is not terrible, The scary thing is that his real-time analytics will expose flaws and truth to people, so when cloud computing encounters big data and a brain pours into companies, can companies manage? The so-called large data mainly covers 3V-oriented, respectively, the Treatment of aging (Veloci ...

(Author Srini penchikala translator Dingxuefeng) for non-relational data types such as documents, object graphs, and key-value pairs, the NoSQL database provides them with an alternative way to store data. Can distributed caching be used as a NoSQL database? Ehcache's Greg Luck author describes the similarity between distributed caching and NoSQL databases. Infoq interviewed him and discussed the pros and cons of the scheme. InfoQ: Can you do a distributed caching solution with the NoSQL database ...

You can think of it as a cloud version of SQL Server, but you can't simply think of SQL Azure as a cloud-built SQL Server. 　　SQL Azure is a relational database that can be deployed in the cloud to provide customers with a service based on a relational database at any time. We can think of it as a cloud version of SQL Server, but it's not easy to think of SQL Azure as a cloud-built SQL S ...

Cloud computing data processing and storage are carried out on the cloud platform, computing resource owners and users of the separation has become the inherent characteristics of the cloud computing model, resulting in users of their own data security storage and privacy concerns are inevitable. Specifically, user data even includes privacy-related content in remote computing, there are potential for intentional or unintentional leaks in storage and communication, as well as data loss caused by failures such as power outages or downtime, even for unreliable cloud infrastructure and service providers, and may be inferred from the analysis of user behavior, Learn about the user's privacy letter ...
