4 Introduction.What is student management System? A Student management system (SMS) is software to manage all day to day operations for a school. They are also called student information systems (SIS), Student information management systems (SIMS), Student records system (SRS). Functionalities of such systems are not the same and this may reflect in the name adopted by users and vendors. Software Requirements 1. Android Studio Android Studio is the official integrated development environment (IDE) for Google's Android operating system, built on Jet Brain's IntelliJ IDEA software and designed specifically for Android development. It is available for download on Windows, macos and Linux based operating systems. It is a replacement for the Eclipse Android Development Tools (ADT) as primary IDE for native Android application development. Android Studio was announced on May 16, 2013 at the Google I/O conference. It was in early access preview stage starting from version 0.1 in May 2013, then entered beta stage starting from version 0.8 which 4

5 was released in June The first stable build was released in December 2014, starting from version 1.0. The current stable version is 3.1 released in March JDK File The Java Development Kit (JDK) is an implementation of either one of the Java Platform, Standard Edition, Java Platform, Enterprise Edition, or Java Platform, Micro Edition platforms released by Oracle Corporation in the form of a binary product aimed at Java developers on Solaris, Linux, macos or Windows. The JDK includes a private JVM and a few other resources to finish the development of a Java Application. Since the introduction of the Java platform, it has been by far the most widely used Software Development Kit (SDK). On 17 November 2006, Sun announced that they would release it under the GNU General Public License (GPL), thus making it free software. This happened in large part on 8 May 2007, when Sun contributed the source code to the OpenJDK. 3. SDK A software development kit (SDK or devkit) is typically a set of software development tools that allows the creation of applications for a certain software package, software framework, hardware platform, computer system, video game console, operating system, or similar development platform. To enrich applications with advanced functionalities, advertisements, push notifications and more, most app developers implement specific software development kits. Some SDKs are critical for developing a platform-specific app. For example, the development of an Android app on Java platform requires a Java Development Kit, for ios apps the ios SDK, and for Universal Windows Platform the.net Framework SDK. 5

6 There are also SDKs that are installed in apps to provide analytics and data about activity. Prominent examples include Google, InMobi and Facebook. It could be something as simple as the implementation of one or more application programming interfaces (APIs) in the form of ondevice libraries to interface to a particular programming language, or to include sophisticated hardware that can communicate with a particular embedded system. Common tools include debugging facilities and other utilities, often presented in an integrated development environment (IDE). SDKs also frequently include sample code and supporting technical notes or other supporting documentation to help clarify points made by the primary reference material. Hardware Requirements 1. Processor Core 2 Duo 2 nd Gen or higher 2. RAM 3GB or more 3. Hard disk 1 GB or more 6
