: Data Access Objects (DAO)DAO means that this is a data access object that is typically used for database interaction. DAO exists to provide read and write data to the database, and they should expose this functionality through the rest of the application by accessing their interfaces. The support of the spring data Access object (DAO) makes it easy to do data access technology in a consistent way with JDBC,HIBERNATE,JPA and JDO. Exec

Ways to handle large messages in WebSphere MQ As readers who have used WebSphere MQ know, WebSphere MQ is limited in size to the single message being processed, the maximum message currently supported is 100M, and the performance of WebSphere MQ processing decreases as the message size increases. From best practices, the message of WebSphere MQ transmission size of k is the most efficient. So how can WebSphere MQ efficiently handle big messages? WebSphere MQ provides two ways to handle large m
