Preface: before developing marklogic application in XQuery language, we should have a general understanding of marklogic, there is not much Chinese material at present, we can only obtain relevant information from the official website https://docs.marklogic.com. MarkLogic provides a considerable number of functions for developers to use, and the instructions for

Originally from: Http://www.infoq.com/cn/articles/MarkLogic-NoSQL-with-TransactionsThe Java platform is painstakingly working to provide the developer with the database persistence functionality for almost the entire life cycle. Have you tried the early JDBC specification, EJB, O/R mappings such as Hibernate, or the recent JPA specification, you are unlikely to have encountered a relational database on this path. Perhaps you already understand the dif

processing capabilities, including JSON, full-text, and geospatial data. But couchdb in recent years seems to have taken the limelight from other NoSQL rivals. It is puzzling that IBM has even established an important partnership with the NoSQL market leader MongoDB. Needless to say, we will see IBM take the next step in this regard. I bet we'll see more database-as-a-service scenarios that take advantage of the cloudant feature. 　　Official website:https://cloudant.com/

needed. Based on some object-oriented advice: "consider what is variable in Design", "encapsulate the concept of change", and "prioritize object combination clustering rather than class inheritance ". Therefore, our practice is: 1. Look for changes and encapsulate them in a separate class. 2. Include this class in another class. An example of the policy pattern given in "going deep into PHP object-oriented patterns and practices: Suppose we have already picked up a markup language, and now th

Eight years of experience using NoSQL Mike Bowers, an Enterprise Data architect at Jesus Christ's late Saints Church (LDS), introduced eight years of experience using NoSQL databases at the recent Enterprise Data World Conference (EDW. He talked about the design basis for selecting a NoSQL database. If a large organization chooses to use a NoSQL database, it will take a lot of manpower and time to convert the relational database into a NoSQL database. It also needs to change the cultural managem

2009, Last.fm's Johan Oskarsson launched a discussion on the distributed open source database, and Eric Evans from Rackspace again proposed the concept of NoSQL, when NoSQL mainly refers to non-relational, distributed, does not provide an acid database design pattern.The No:sql (East) symposium, held in Atlanta in 2009, was a milestone with the slogan "Select Fun, Profit from Real_world where Relational=false;". Thus, the most common explanation for NoSQL is "non-relational", emphasizing the ad

each shard, such as master-slave replication.Despite these shortcomings, sharding is widely used for some large sites, such as Google, EBay, Facebook, and Flickr. When the pain are great, any medicine this reduces it is good, regardless of the side effects.This sentence is a bit of a meaning. Of course, there are some other new database architectures that can be scaled out, such as the extension of NoSQL for OLTP, and Hadoop for OLAP. However, this is beyond the scope of this arti
