; Next (); }); }); Questionschema.set ( ' Toobject ', {getters: true }); As a result, each time question executes the Save method, the function is called to obtain the most recent ID after the increment. Backup and import of database backup and import of course is necessary, for example, you can take this my backup files directly into the practice, so that the step-by-step creation of the steps are omitted. To back up a database you can use the Mongodump command using the following: Mongodum

building a Web application with spring MVC features and benefits of 1.Spring MVC A Layered Java Web development framework Model Model is the representation of specific domain information used by the application View A view is a representation of a domain model Controller The controller is primarily responsible for interpreting the user's input and converting it

When creating a web app running on a mobile phone, we need to consider the offline usage of the user in view of the Network Situation of the mobile phone user. HTML5 supports building offline applications. Using its local cache mechanism, You Can cache all the resource files required by the application to the local, so that the application can be used offline. Th

GWT makes it easier to build a rich Ajax browser client interface than to build a traditional Java GUI interface. However, even a good technology like GWT cannot build a complete WEB application on its own. You must also have a data store on the server and a type of framework to convert the data into a Java object that GWT can pass to its customers from the server. In this series of articles, you will use Apache Derby, the 100% pure Java database, to

1. What is application settings?Application settings usually refer to a series of parameters closely related to the application. In Windows applications based on forms, application settings mainly include parameters such as location and size that affect the application layout, and parameters such as color and shape that affect the application appearance. In addition, it also includes application language, c

This article is part 2nd of the building of the asynchronous JavaScript + XML (AJAX) application series using Google Web Toolkit (GWT), which describes how to build an Apache Derby database for your WEB application and use it to drive Move GWT. Part 1th of this series introduces you to GWT and demonstrates how to use it to create a rich client front-end for your

services, or EJB methods with the help of blazeds remote technology. Developers can send messages from the client to the server via their messaging system, and, of course, send messages from the server to the client side. BlazeDS can also be used in conjunction with other messaging systems, such as JMS, ActiveMQ. Because of the way in which remote technology and message systems are used to transmit AMF data on HTTP protocols, BlazeDS has a great advantage in performance and avoids the processin

In this article, you will install and configure the backend of the database--web application to create a database schema and learn some simple tools to populate it with data. The database that you will be using is the Apache derby,100% pure Java™ relational database, which was originally developed under the name of Cloudscape™. Finally, IBM® acquired the Cloudscape code and then contributed its open-source version to the Apache project. The same proje

The tool has a built-in version control feature that automatically generates a new version each time the profile is modified. After the Cluster service is started, the "Cluster Manager" appears, with the contents as shown in the image on the right.
