- 1. How do opensource projects work? How is it different from closed source projects? Discus the creation of a database. Explain its working. (E.g, what you need to use to create tables and relationship? What you do to modify a database?) Explain what's SaaS, PaaS and laaS? Distinguish among these three. Solution 31) In open source project the source code of the project is made available to anyone for free. The code can be studied, modified and even redistributed for any purpose.Many of the open source projects are developed in an open collaberative manner. People volunteer to develop the projects.Where as in closed source projects the source code is not developed by an organization and the source code is not openly available. 32) A database consists of many tables created for a project. In mysql it is created using the command 'create database sample_database;'. We generally use a RDBMS(Relational Database Management System). The data is stored in RDBMS database objects called tables. You can create a table by specifying the number of rows, names of each row and the type of data that will be stored in each of them. 33) SaaS means software as a service in which a software is provided as a serive. Generally the service is centrally hosted, but this many not always be the case. The consumer is charged on a one time basis or in a subscription model. PaaS stands for platform as a service. The service provides platform as a service for customers to develop, manage and run applications. This is generally referred for cloud computing applications. LaaS stands for logging as a serivce. This represents a architechture used for collection of log files from a specific location or source.
