With the popularity of the Internet and the continuous development of network technology, the confidentiality requirements of data are more and more high. In the usual server/client mode mis development, because the program to maintain the connection with the database server, for the flexibility and extensibility of the program, the join parameters (user ID and login password) can not be written in the program death (in fact, writing death is not a good way), There are two kinds of general methods: one is to store the join parameters in the registry, and the other is to read the INI file directly. And the safety of several methods are not very good, give people the opportunity. Myself...

The relationship between big data and cloud computing has caused some confusion. In order to facilitate the discussion of the relationship between the two, from the "calculation" and "data" of the historical relationship. Because cloud computing is first a kind of "calculation", large data is first a kind of "data", and computer is used to "calculate" "data". Computers are software-and hardware-separated, a software-defined electronic product (programmable). An important issue in computer design is how to effectively manage hardware resources such as CPU, memory, and I/O, and how to make these resources reasonably available to applications. These two major tasks are embedded in various ...

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 ...

The AJAX-based attacks described in the previous article have many questions, such as not being able to cross domains and lighten the burden. Ajax is delivered through simple get and post, using Httpdebugger, fetching data, and then using the following scenario, 　　By the way, write an example of the attack code. More than the traditional webform, we are more likely to construct some, in fact, for WebForm and Ajax processing and contract process is the same, Ajax data volume relatively small, faster. Combine Sharppcap and Httpwebr ...

SQL injection attacks are known to be the most common Web application attack technologies. The security damage caused by SQL injection attacks is also irreparable. The 10 SQL tools listed below can help administrators detect vulnerabilities in a timely manner. bSQL Hacker bSQL Hacker was developed by the Portcullis Lab, bSQL Hacker is an SQL Automatic injection tool (which supports SQL blinds) designed to enable SQL overflow injection of any database. bSQL ...

Hadoop technology is everywhere. For better or worse, Hadoop has become synonymous with big data. In just a few years, Hadoop has become a de facto standard from an edge technology. It seems that not only is Hadoop now a standard for corporate data, but its position in the future seems to be hard to shake. Google file system and MapReduce let's explore the soul of Hadoop--mapreduce. Faced with the explosive growth of data, ...

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 ...
