Referring to data mining, our first reaction was before the story of beer and diaper heard that this story is a typical data mining association rule. The difference between the main differences between traditional linear regression of basket analysis and the correlation analysis of discrete data;Common Association Rules:Association rules: Milk = egg "support =2%, confidence =60%"Support: 2% of all transactions in the analysis the same time the purchase of milk and eggs, you need to set the domai

blocked, and it is very likely to be deadlocked.3. There is a possibility of exclusive transactions, because if a session's transaction runs for too long, it exclusively shares resources, and other users can only wait. (dedicated server, each client is a session)4. The Shared Server Mode limits some database features, such:The instance cannot be started or shut down independently, and media cannot be restored. Log Miner cannot be used, and SQL _TRACE

practices . 　　This paper mainly discusses the implementation of generics in Java syntax. Here is a brief summary of what I read from the previous article:Generics are a mechanism for more extensive application of parameter types as parameters, and in C + +, C # There are similar mechanisms for templates and generics. Generics in Java are different from the generic implementation mechanisms of other languages, and are a pseudo-generic based on erasure. For example, list2.2.1) ERROR 1222 (21000)

is through the mining of logs (Oracle's log miner and IBM db2/400). But the ODI CDC must require the source table to have a primary key.second, the problem of deleting data introducedWhen we start using ODI for data synchronization in CDC mode, everything is OK, and the deleted data can be correctly synchronized to the target database. Then, becauseBusiness requirements, we only need to synchronize some of the data to the target database, that is, th

, the BI querying software directly connected to the business database, but must limit the load, prohibit the complex query.The current database products are specifically optimized for the data warehouse, for example, when installing a high version of MySQL, the installation sequence will ask whether you want the database instance as transaction-oriented, or decision support, the former is the operational database, The latter is the Data Warehouse ( decision Support , and then effigy again), for

Val and the filtered validate are not basic properties. So the idea of the solution should be shifted to the mailbox body display should be based on the most basic attributes.6. Still follow the line of thought 1, select using Val to specify the selected item, instead by option selected, replace with regular expression, the code is as follows:if (Readhtml.contains ("select")) {String regex = "value=\" "+ Value +" \ "";String str = readhtml;Pattern Pat = pattern.compile (regex);Matcher Matcher =

process data with historical data. This thought once made me waver in my understanding of the fundamental differences between the two. Actually testing is not union/unionall caused. See: Union and UNION ALL differences Querylist a WHERE id! = 0 The code is written by another colleague who has left it, and it is unclear (perhaps because the ID returned is not its true ID when querying historical data, but it is unified as "0", and this code is inexplicable); Querylist a more order; I
