In the past few years, the innovative development of the open source world has elevated the productivity of Java™ developers to one level. Free tools, frameworks and solutions make up for once-scarce vacancies. The Apache CouchDB, which some people think is a WEB 2.0 database, is very promising. It's not difficult to master CouchDB, it's as simple as using a Web browser. This issue of Java open ...

Sqlbuilder is a SQL build library that reduces the burden of generating SQL queries in Java programs. It uses a programming language (Java) to generate code (that is, SQL) for another language. It is characterized by encapsulating SQL syntax in lightweight, Easy-to-use Java objects, following a builder paradigm similar to StringBuilder. It can change many common SQL syntax and run-time errors to Java compile-time errors. A simple SQL SELECT embedded in a Java program ...

Cost comparisons are easy for cloud computing providers, but performance comparisons for applications are not as simple as comparing performance comparisons of the different types of database applications running in the same cloud or across different cloud computing environments. The Yahoo Cloud computing Service Benchmark (YCSB) is a test framework designed to help users understand the performance of different cloud computing databases and store data performance under actual load. The source code for this test framework is available from the GitHub download. Yahoo cloud services benchmark tools include ...

It is easy to compare the cost of cloud computing vendors, but it is not easy to compare the performance of the application. A performance comparison of the different types of database applications running in the same cloud or across different cloud computing environments will be a particularly challenging task. The Yahoo Cloud computing Service Benchmark (YCSB) is a test framework designed to help users understand the performance of different cloud computing databases and store data performance under actual load. The source code for this test framework is available from the GitHub download. Yahoo cloud services benchmark tools include ...

. NET always supports optional parameters, but the C # language does not support that optional parameters are usually prohibited except for invoking a COM library. Now, with the support of C # 4 for optional parameters, we can see that optional parameters are being used more and more, not just in legacy code. 　　These applications include interoperability with dynamic languages, read-only data types, and many places in asp.net mvc. Obviously, COM is still the main option for optional parameters. For example, when you use the Office library, a function may have more than 20 ...
