由 折月煮酒 提交于 2019-12-12 01:58:12
问题 My current application includes a functionality of displaying a report designed in iReports 4.1.1 from Spring MVC at front and using PostgreSQL at back. Now i am more of concerned about its performance issues. The Main report which will display data has as many as 20 subreports at most. and each subreport has high cost query running for it. So what are the chances of having performance issues when the user count increases (in short when application scales)?? And if there is any such potential

如何用开源bi，打造自己的轻量级bi系统

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 对于程序员来说，开源的东西都是好的，别的不说，因为可以自己自己随意开发，毕竟每个人都喜欢自己写的代码嘛，也或者，就是不想花钱哈哈哈哈（扎心了） 就拿最近很火的BI来说吧，BI分两种：开源BI和商用BI，说起开源BI就是有爱又恨，这一切都要从微软带起了商业风说起.... 我在网上搜到了一下2018年BI的市场占有率： 说到软件，可能第一反应就是国外的好，于是就先尝试了国外的开源BI。第一个接触的开源BI是pentaho，实在是太臃肿了，花了半年时间没有搞定，bug又多，修改不了。第二个是superset，可视化很强大，不过需要安装Linux，对于非技术人员很不友好，毕竟现在的BI都主打自助式。第三个开源BI就是JasperReports了，这是程序员最受欢迎、最常用的开源报表工具，常和ireport一起搭配使用，不过它有两个致命的缺点：需要学习编程，不支持多源数据源，这无疑是把自己未来的路给封死了....使用了这么多之后，我们决定试试国内的开源BI。 国内的开源BI很多都是假开源，阉割很多核心功能，或者是商业用就要收费。而BI产品又很贵，在商业bi用的比较多的就是tableau，sever价格10万，10个账号，增加一个账号需要1万。由于最近要给公司实施BI，和工程师聊过，如果自己开发一套BI的话，工作量非常大

How do I hide a table that has no data on ireport?

由 穿精又带淫゛_ 提交于 2019-12-11 13:05:15
问题 How do I hide a table (not include in layout) that has no data? 回答1: If you have the table on its own band, what I typically do is set a print when condition on the band that only shows the data if any object in that band has data. Say your table is something like this: item1 item2 item3 The print when expression would look something like this: item1 != null || item2 != null || item3 != null If you're referring to a subreport built using a collection, then I just check to make sure the
