The traditional method of software development is tightly coupled on the server-side and client-side which creates a limitation on faster parallel development, it is also difficult to scale these types of applications and they can’t handle multiple clients easily. With the ever-increasing demand for mobile technologies for your products. It’s difficult to have the same database and codebase for all your applications. Exposing data is difficult.
Development is time-consuming, this is were REST API comes in place. It allows a single codebase on the server-side to work with all your applications. You don’t have to write the server-side code more than once and programming language doesn’t matter which results in faster software development and easy data sharing.
COURSE OUTCOME
- Speeds your project development process.
- Able to work efficiently in a team.
- Able to write server-side code for web, mobile, desktop applications in a single language of your choice.
- Able to use the same database for all your projects without data redundancy or database duplication.
- Able to work on any type of application, due to language independency.
PREREQUISITES:
- Knowledge of any programming language with basics of the database is enough.
- Working experience in projects is plus.
OBJECTIVES
- Understanding the basics of REST API
- A better understanding of database concepts
- Use open-source API like maps, data, images, news, etc.
- Create your REST API endpoints for your project.
- Use your own endpoints from multiple projects.
- Learn to share data publicly through API.
WHO CAN JOIN REST API?
- Students who have basic programming knowledge (any language)
- Basic knowledge of the database.
- Worked on at least one project with the use of the database.
This course is also beneficial for the professionals working in the software field those who:
- Are working on projects regularly.
- Develop projects for multiple platforms (Web, Mobile, Desktop) and want to use a single code for all.
- Have knowledge of one or more programming languages but want to contribute to different platforms.
