I just read the article about oracle efficient design. When it comes to Standard Quantum queries in oracle, the performance depends on associated queries, however, I know in SQL server that the performance of associated queries is better than that

Tags: style color ar os using SP data div onIn the process of driving big data projects, enterprises often encounter such a critical decision-making problem-which database solution should be used? After all, the final option is often left with SQL and NoSQL two. SQL has an impressive track record and a huge installation base, but NoSQL can generate considerable revenue and also has a lot of supporters. In today's debate, we will listen to the views of the experts in the two camps together.John D

perspective. I don't want to be implemented in an attached way, I don't want it to be an option, not the only answer, and I don't want to be forced to set up a technical team to work with a dedicated maintenance company. The traditional relational data processing scheme is cumbersome and complex, and it seems to me to be unable to deal with the scale of globalization. ” In a large-scale cloud deployment system, the inclusion of NoSQL can provide us with strong support. We've also heard a lot ab

Developing a database system application on the operating system is much like developing a mobile app. There has been a flourishing development. Because big data is still a hot topic at the moment.

. With the rapid growth of the user base, we have spent a lot of money to buy more hardware and software is useless. The last thing we want is to lose customers. Where do we go from here?We decided to split our online user base and run our online games on NOSQL and Newsql. Our goal is to find the best solution. The IT department then chose the NOSQL couchbase (similar to MongoDB's document-oriented) and Newsql Voltdb.Couchbase is open source, it has a

query functions of SQL database, such as Couchbase's index and MONGO's complex queries. Support for transactions can also use some system-level atomic operations to implement methods such as optimistic locking to curve the salvation. SQL database also began to evolve slowly, such as the implementation of Handlersocker technology, can be implemented on the SQL layer of MySQL penetration, in a nosql way to access the database, performance can be achieved or even beyond the NoSQL database. scalabi

instance directs the client to automatically read and write data to the instance. Redis cluster member management (node name, IP, port, status, role), etc., are exchanged and updated periodically through 22 of communication between nodes. Thus, this is a very "heavy" scenario. is no longer "simple, Redis" for a single instance. Perhaps this is one of the reasons for the recent release after years of delay. This is reminiscent of a history. Because Memcache does not support persistence, so
