A framework that simplifies the development of administrative tools

The Boot tab lets you configure boot options such as Safe Mode. The Services tab lets you enable or disable services. The Startup tab lets you see and disable all of the applications that Windows 7 is starting automatically.

The Tools tab gives you easy access to a variety of system tools such as the Registry Editor. Task Scheduler: It lets you create system maintenance tasks that are performed on a regular schedule or when system events occur.

New features include a history log and additional trigger mechanisms. It is able to configure advanced settings for Windows Firewall that are not available through the Windows Firewall applet in Control Panel. IPSec is a protocol used to encrypt data com- munication over the network. This tool was new in Windows Vista.

Windows Memory Diagnostic: It is used to to perform tests on the physical memory of a computer running Windows 7. The physical memory of a com- puter cannot be tested when Windows 7 is running because the memory diagnostics tool needs access to test all of the memory, including the memory used by Windows 7. OPSS also enables you to use Java EE container-managed security, which provides a more coarse-grained authorization model. Instead of granting access to individual users, you can group users into application roles and grant permissions to the role.

You grant users or roles access rights to a given resource. A security policy is an access right that you grant for a given resource. Ultimately, it is the security policy on the ADF resource that controls the user's ability to enter a task flow or view a web page. For ease of administration, you can also create entitlement grants, under which you aggregate multiple resources in a security group. This enables you to set the security policy for multiple resources in one place.

Resources for which such permission classes exist are known as security-aware resources. Any web page associated with an ADF security-aware resource is protected by default unless you explicitly set a security policy granting access to the resource.

This section outlines the features and physical artifacts that are at the core of the ADF Security framework. The design-time integration with OPSS for an application is configured declaratively through several metadata files, which are configured automatically when you use JDeveloper's security wizards and visual editors.

The following are the key files affected:. The user interface project's web. A web resource for the oracle. AuthenticationServlet servlet and mappings to require the user to log in the first time the application is accessed and to set the appropriate security constraint to trigger user authentication dynamically.

Required security roles, such as valid-users , which is used to trigger the security constraint that enables dynamic authentication. The application workspace's adf-config. The application workspace's jps-config. Though this file may be deployed as part of the application EAR file, it is not used at runtime. Instead, a version of the file that is stored in the server instance's domain is used. The application's jazn-data. When you deploy the application to Oracle WebLogic Server, by default the server copies users and groups in jazn-data.

Before deploying to a production server, you should delete all users and groups that you create in the jazn-data. The application's weblogic. Figure shows the security artifacts that are created and configured in JDeveloper and how they map to the runtime security architecture of Oracle WebLogic Server.

The following types of resources in ADF applications are security-aware and can be configured with individual security policies:. ADF bounded task flows. NET framework is 4. The following features characterize ASP. NET as a back-end development framework:.

NET allows us to include packages that your need for the application. This ultimately improves performance and scalability. It allows you to build a class library that can be used with other. NET frameworks such as. NET Framework 4. Hence, a single code base can be shared across different frameworks.

NET follows the MVC architecture, which allows for separate input, process and output of the application. The framework comes with an incredibly rich toolbox through its Visual Studio integrated development environment. It helps developers to create applications very quickly with features like drag-and-drop server controls, WYSIWYG editing and automatic deployment.

It also comes with features like just-in-time compilation, early binding, native optimization and caching services. NET can help you develop secure applications through built-in Windows authentication and per-application configuration features. The framework language allows for easy cross-platform migration, configuration, and deployment services. This leads the hosting providers to charge an extra cost for their services. The documentation of the framework is not as good as you want it to be, and when you build MVC apps, you could face issues.

You need utilities like Internet Service Manager to access the Metabase, as it is stored in the proprietary format on the server machine. The PHP framework, Laravel is free and open-source. It comes with API support and holds a decent amount of packages that could extend its reach.

The applications developed with the Laravel framework ensures elegance, simplicity, and readability. Its large community assures the resolution of programming problems and issues in the minimum time possible. In addition, it also offers informative blogs, online forums, and expert opinions for hassle-free coding.

The following features characterize Laravel as a back-end development framework :. Its inbuilt lightweight templates help you create amazing layouts using dynamic content seeding. Laravel framework creates innovative designs of a simple layout with different sections. The MVC architecture allows better documentation, improved performance and has multiple built-in functions.

Laravel incorporates all the latest PHP features like namespaces, overloading, anonymous functions, interfaces, and shorter array syntax. Each version of the framework was released with appropriate documentation, featuring comprehensive and easy to understand descriptions when it comes to classes, approaches and code types.

Such detail-oriented documentation is what makes the framework really developer-friendly. When compared to other frameworks such as Ruby on Rails and Django, Laravel has limited inbuilt support due to it being lightweight. The Yii PHP framework is an open-source framework used for building reliable web applications. It is designed with the Model-View-Controller pattern. The framework has inbuilt security features to develop robust applications.

Yii framework facilitates customization of applications with rapidly changing business requirements. This web development framework comes with the in-built component-based model, database abstraction layers, event-driven programming features, and modular application architecture. The following features characterize Yii as a back-end development framework :. Yii framework has several security components that have several methods which help to create a more secure application.

It provides several tools to enhance the speed of application. It offers the highest number of requests per second. It is the fastest available framework for developing large-scale applications.

Its seamless and faster performance make it suitable for developing forums, e-commerce frames, content and data management systems, and much more. Its architecture helps the developer to craft a smart website keeping its database servers isolated from the users and helps the developer to build effective web applications.

The uniquely designed controller helps to link different libraries and packages, eventually decreasing the programming load from the developer. It allows the third-party interface, thus allowing different frameworks to be merged with Yii, making it more powerful than any other framework present today. It gets easy to debug the program because of its simpler code format.

Also, the OOPs allow the developer to add different extensions and widgets as per requirement. The Ajax features are not well-drafted or built, and so, developers have to use JavaScript when needed compulsorily. Yii seeks greater attention from the developer while developing the application, as one mistake and the program can get oversized. Learning Yii requires quite enough knowledge about PHP language, programming skills, and the different add-ons it comes with.

Sometimes it gets boring and difficult for beginners to learn from it. CodeIgniter is a PHP framework that develops web applications faster. The framework owns rich libraries for developing connections to the databases and performing other operations. It enables PHP code easy to use and helps develop engaging, seamless and dynamic websites in a short period of time.

It makes your web more robust and your code easier to read and maintain. Most businesses today c hooses PHP for developing enterprise applications. The following features characterize Codelgniter as a front-end development framework :. CodeIgniter has components for sending email, database management, session management and many more. The source code length of the CodeIgniter framework is almost 2MB.

Deployment and updation are quite easy in it. The built-in features of the framework work independently without relying on other components.

It is easy to maintain and upgrade. CodeIgniter framework uses the Model-View-Controller to separate the data, business logic, and presentation. CodeIgniter is designed as a lightweight PHP framework. The clear documentation and robust community support further make it easier for PHP programmers to use CodeIgniter for the development of a variety of web applications. But it still encourages developers to speed up the development of large and complex web applications by implementing MVC in a different way.

CodeIgniter further helps programmers to speed up web applications by implementing both page and database caching. It reduces server load by allowing developers to cache web pages in their fully rendered state. CodeIgniter makes it easier for programmers to write secure PHP applications by providing a number of features.

CodeIgniter does not support the modular separation of code by default. Developers need to put time and effort to update the code. It is quite popular due to its faster development of applications in a limited time and effort. The following features characterize Django as a back-end development framework :. It ensures that the deliverable is efficient as well as cost-effective. It is the best fit for projects having tight deadlines and where time is a priority.

It has a robust security system in place. Its user authentication system provides a safe way to manage user accounts and passwords. Django helps developers by speeding up the development process.

It includes its own Object Relational Mapping ORM layer for handling database access, sessions, routing, and multi-language support. From idea, production to release, Django helps in making it both cost-effective and efficient. Thus it becomes an ideal solution for developers having a primary focus on deadlines. It significantly speeds up development. Django, unlike other modern web frameworks, does not enable individual processes to handle multiple requests simultaneously.

Unlike other modern web frameworks, Python does not keep the components of a web application loosely-coupled. The improperly designed architecture combined with Python may lead to slow down the websites. This framework also has its own benchmarks to check the bottlenecks.

Small websites, like static one-pagers or microservices, can not be built using the Django framework. The two robust and powerful backend frameworks are ruling the backend development industry. Let's first have a look at the popularity of the two PHP frameworks in the development world. It will make your vision towards frameworks more clear. As you can see in the Google trends result, Yii framework is more popular than laravel.

Let's first have a look at the popularity of the two JavaScript frameworks in the development world. As you can see in the Google trends result, Angular is performing much better than Node. The competition between the two front-end frameworks is neck-to-neck. Also , You need to go through the comparison table to understand how they are different from each other. This chapter discloses all the powerful database management systems to help you store your data safely and securely.

A database is a systematic collection of data. They support electronic storage and manipulation of data. Databases make data management easy. For example: An online telephone directory uses a database to store data of people, phone numbers, other contact details. Your electricity service provider uses a database to manage billing, client-related issues, handle fault data, etc. Databases are basically logical structures that are used to organize and store data for future processing, retrieval, or evaluation.

A database is usually controlled by a database management system DBMS. The data is stored in the form of tables consisting of rows and columns to make processing and data querying efficient. The data can then be easily accessed, managed, modified, updated, controlled, and organized. MySQL is considered one of the most popular databases for web-based applications.

It's freeware, but it is frequently updated with features and security improvements. It consists of a multi-threaded SQL server that supports different backends, several different client programs and libraries, administrative tools, and a wide range of Application Programming Interfaces APIs.

It can also provide an embedded multithreaded library that you can link in your application to get faster, smaller, and easy to manage standalone products. MySQL provides cluster servers. MySQL is very easy to install and has third-party tools that can be added to the database, setting up implementation is a relatively simple task. There are a variety of user interfaces that can be implemented and can be made to work with other databases, including DB2 and Oracle.

Although MySQL is relatively easy to set up, it tends to have less out-of-the-box functionality than many other database systems on the market. MySQL tends to be somewhat less reliable than its peers. These stability issues are related to the manner in which it handles certain functions. It is a highly scalable, flexible, and distributed NoSQL database. Instead of using tables and rows as in the traditional relational databases, MongoDB makes use of collections and documents. Documents consist of key-value pairs which are the basic unit of data in MongoDB.

Collections contain sets of documents and functions which is the equivalent of relational database tables. MongoDB can run over multiple servers. The data is duplicated to keep the system up and also keep its running condition in case of hardware failure. It supports Master—Slave replication. MongoDB uses native applications to maintain multiple copies of data.

The data model available within MongoDB allows you to represent hierarchical relationships, to store arrays, and other more complex structures more easily. MongoDB scales elastically in terms of data volume and throughput. The technology gives you enough flexibility across various data centers with good consistency. The flexible data model with dynamic schema, and with powerful GUI and command line tools, makes it fast for developers to build and evolve applications.

Costs are significantly lowered as MongoDB runs on commodity hardware. Yet one can use joins functionality by adding by coding it manually. But it may slow execution and affect performance. MongoDB stores key names for each value pair. Also, due to no functionality of joins, there is data redundancy. This results in increasing unnecessary usage of memory. To achieve the performance and scalability, MongoDB ditches the transaction support.

This makes MongoDB very easy to scale horizontally which utilizes many cheap hardware to balance the load. A tech stack of your web or mobile app not only affects the speed and timeline of the development but also influences the ability to scale it in the future. This chapter will tells you about all the development stack that developers can use to develop powerful and robust applications. Choosing the appropriate tech stack is quite a challenge nowadays. Your business needs technology stacks that deliver you high-end services and at the same time boosts your ROI and enhances growth.

MEAN stack is a technology stack which is a user-friendly full-stack JavaScript framework for building dynamic websites and applications. Each of these components has a particular use. ExpressJS : Is a web application framework for Node. It enables you to build server applications in Node. AngularJS : Is a frontend technology in the stack. It regulates the behavior of different elements showcased on the web page. It is used to run JavaScript on a machine instead of a browser.

Developing applications using Mean saves a lot of time. It not only saves your time but also creates quality world-class applications. Mean stack is considered flexible and scalable. You can simply test the application here on the cloud and also add extra information to your form.

The developers enjoy using MEAN because it works for both server side and client side requirements. The technologies in stack are open source, making them available and free.

This gives you easier access to public repositories and libraries making the development process easy and less costly. This is probably why developers prefer this tech stack for various stages of app development. It offers poor isolation from the server from business logic. MongoDB is strongly consistent. But, when network partitioning occurs, especially in heavy load scenarios, there is a chance that you could lose records that has been successfully written by MongoDB.

The technology stack is a set of frameworks and tools used to develop software applications faster and easier.
