In System Design, there are two types of approaches followed namely, the Bottom-Up Model and the Top-Down Model. The bottom-up model is one in which the different parts of a system are designed and developed and then all these parts are connected together as a single unit. On the other hand, the top-down model is one in which the whole system is decomposed into smaller sub-components, then each of these parts are designed and developed till the completed system is designed. Read this article to find out more about the bottom-up model and the top-down model of system ... Read More

In database management systems (DBMS), there are two terms namely mirroring and replication which are related to copying of data. Mirroring is defined as the process of copying a database to another location, while replication is defined as the process of copying the database objects from one database to another.

JPEG and SVG are types of image formats. JPEG is a raster image format that uses a lossy compression algorithm to compress an image, whereas SVG is a highly scalable, text-based image format that uses mathematical structures to represent an image. JPEG images are used in photography applications, while SVG is used when high-resolution images are required. JPEG is a good choice for photographs and other images with lots of colors, while SVG is a better choice for simple images and graphics that need to be resized, such as logos and icons.

Anybody dealing with databases must comprehend the distinction between DDL and DML commands because it has an impact on how data is saved, accessed, and modified. A collection of commands called DDL are used to specify a database's structure. Database objects including tables, views, indexes, and constraints can be created, modified, and deleted using these commands. DDL statements specify how the data is arranged and accessed rather than altering the data that is stored in the database. DML, on the other hand, is a set of instructions used to work with the data that is kept in the ... Read More

GIF and PNG are types of image formats to store images. Both GIF and PNG are pixelbased image formats. Both use lossless compression algorithms and support transparency. GIF images support animation as well. Read this article to find out more about GIF and PNG formats and how they are different from each other. Let's start with a brief overview of these two image formats. What is GIF? GIF stands for Graphical Interchange Format. GIF is an image file format that uses lossless compression algorithm. Therefore, the GIF images are of high quality, but a GIF image supports only 256 colors. ... Read More
