With the weakness of relational database in some aspects, to understand the characteristics and performance of the current popular database patterns will undoubtedly provide us with more choices and directions. Neo4j is a kind of graphic database, which has outstanding advantages in traversal and associated query. Cut the crap and get to know the neo4j before you let us try how to use

5000 items are observed according to the test), we recommend that you use the transaction-Type Insert interface (usually the data operation interface of NEO4J), the speed is still acceptable; when the data volume is large, we recommend that you use the dedicated BatchInserters interface, which does not create transactions during insertion. It is estimated that the memory usage is very small. Basically, the memory remains unchanged during operations o

Getting started with Neo4j (2): matching ModesAnnouncement: All data comes from the book "Building Web Applications with Python and Neo4j", just for study not for commerce.Pattern and Pattern matching are the core of Cypher and describe the shape of the data we want to find, create, or update. If you do not understand the pattern and pattern matching, you cannot write effective and efficient queries.I. Dat

: participle word frequency statisticsYou can use the open source word breaker, which is used in this example. .Step three: Manual selection of main materialThe higher the frequency of the main material, in the name of the dish appears more frequently, the more valuable screening; words with a word frequency of 1 can be used without screening, because even the main material, there is no other dish can be recommended. Fourth step: matching the main material algorithmThe specific algorithm can be

Label:NEO4J's JDBC connection is actually sending an HTTP request (using the httpclient), for Chinese, when inserting data, JDBC uses UTF-8 encoded post submission, but when the Chinese data is returned, it does not indicate that the data is UTF-8 encoding. Therefore, HttpClient will use the platform to parse the data, if the platform encoding is GBK and other coding, the good case, the platform can be encoded after parsing the resultset, and then the correct code to parse the data; in bad cases
