Multiple applications updating single database in java
Elastic Beanstalk is an easy-to-use service for deploying and scaling Java web applications.
Elastic Beanstalk supports several platform configurations for Java applications, including multiple versions of Java with the Apache Tomcat application server and Java-only configurations for applications that do not use Tomcat.
This might not be the best model for a web app though since the Model had to broadcast changes to the Views, which might not be the easiest w/ a web client.
Amazon Web Services (AWS) is a great platform for running Java workloads, and offers several options for deploying and managing both off-the-shelf and custom applications.
sent to be committed) it reverted to using the underlying Model's info.
I also had an undo stack with all the changes the users made so that things could be reverted.
List; The connection string mostly follows RFC 3986, with the exception of the domain name.
There's a project I'm working on that is looking to produce a web application that will manage a task list between multiple users.
I am trying to leave details of the project out of this as I'm grappling more with the overall concept of how to handle the following situations, but if it helps, I'm using Java, Eclipse Link, and GWT with Request Factory implemented. So the conceptual problems I am attempting to reconcile are the following: I think Whiteboard will be your pattern of choice for #1, you should post changes to tasks (or other shared data) in a common place, so all interested parties can see them and DTRT. Basically, you need to timestamp all your editable records with the last update time.
When you try to save the record, you first verify that the record in the database has the same last-updated timestamp as your record.
If not, then someone has updated the record and you now have to either get the updated record and inform the user that they need to enter their changes again, or you can try to merge the user's changes into the updated record (which usually turns out to be either simple or impossible).
I came up with a design for a desktop application (that has yet to be fully tested) with similar requirements that might be helpful.
SQLite is not directly comparable to client/server SQL database engines such as My SQL, Oracle, Postgre SQL, or SQL Server since SQLite is trying to solve a different problem.Tags: Adult Dating, affair dating, sex dating
