Online Learning Management System ( SRS )

A crucial tool for both teachers and students in the current digital age is the Online Learning Management System (LMS). The centralised platform our system provides for online course delivery, content management, and progress monitoring transforms the way we teach and learn. Enabling instructors to design captivating learning experiences while giving students flexibility and accessibility is made possible by the LMS’s interactive capabilities and user-friendly interface. To improve the online learning experience, we shall examine the process of creating a System Requirements Specification (SRS) for an LMS.

In software development, gathering requirements is the most important method. Such a process includes obtaining the needs and wishes of all stakeholders and taking into account any specific expectations to develop a system that will be successful and meet all requirements. During online learning management system implementation (LMS) requirement gathering, it is necessary to analyze the needs of educators, adult learners, administrators, and other parties who participate in learning.

We develop a detailed Software Requirement Specification for Learning Management System, in this process which will have all the details about the project from Technical to Non Technical Requirements.

Class Diagram and Characteristics

Class Diagram for Online Learning Management System simply describes structure of Learning Management System class, attributes, methods or operations, relationship among objects.

Aggregation:

• Aggregation simply shows a relationship where one thing can exist independently of other thing. It means to create or compose different abstractions together in defining a class.
• Aggregation is represented as a part of relationship in class diagram. In diagram given below, we can see that aggregation is represented by an edge with a diamond end pointing towards superclass.

Multiplicity:

• Multiplicity means that number of elements of a class is associated with another class. These relations can be one-to-one, many-to-many, and many-to-one or one-to-many. For denoting one element we use 1, for zero elements we use 0, and for many elements we use *.
• We can see in diagram; many users are associated with many books denoted by * and this represents a many-to-many type of relationship. One user has only one account that is denoted by 1 and this represents a one-to-one type of relationship.
• Many books are associated with one librarian and this represents many-to-one or one-to-many type of relationship. All these relationships are shown in diagram.

No-functional requirements identify how fast the system will work, what will be usability level, how will be security, and other quality features.

Performance

• Ensure the system is a responsive one and supports massive user activity (capacity) and concurrent use.
• Throughout 2 seconds as user takes actions, the system should respond interchangingly to provide a smooth user experience.
• The system should be able to deal with at least 1000 concurrent users, without the system’s performance being affected by the number of users or bandwidth.

Usability

• Design a friendly interphase, that addresses the needs of many users with different levels of familiarity.
• The need for a simple, common design has to be satisfied using a simple user interface with clear labels, a well-ordered layout, and intuitive controls to help reduce the learning curve for new users.
• The system should be designed to accommodate various languages to attend needs of users from various regions and who speak other tongues. language selection should be found in accessable and user-friendly way.

Security

• Assure users’ personal data confidentiality as well as integrity and accessibility of this data and system resources.
• Use a strong MFA, password policy with account lockout after false login throbs to prevent unauthorized login to the system.
• All sensitive data in both residing databases and in transport should be encrypted by the industrial-standard encryption algorithms to prevent stolen data and unauthorized access.
• Data available at all times in case of system failure, disaster, or data corruption should be done via taking ‘scheduled backups’ on regular basis which maintains the data integrity.

Scalability

• Make it so that the system can be enlightened to clone itself, with time, to welcome an extensive number of clients and courses, but without performance loss.
• The system plan must provide support for the horizontal scaling regulations, that is, by making more resources available on demand whenever additional workload is detected as the user base swells.
• Build in load balancing mechanisms to distribute requests for content across multiple machines or values and ensure that you can deliver top performance at peak times.
• Similarly, a database should be designed that is optimized to field increasing data volumes effectively, not to mention scaling options like partitioning, sharding or scalable database solutions such as NoSQL databases cater for growing data demands.

Out of the non-functional requirements this is what you should adhere to such that your system performs well and in addition you need to give security to the users while at the same time it is scalable and it has users that are growing and has several course options.
