How is a relational database system different from other databases in tabular form?
To put it simply there are many types of data systems. But we'll just talk about two of the most common here: The first is commonly known as flatfile. The flat file is pretty simple: Each major category of data (e.g. Employees) is contained in a single file. If that employee can have multiple phone numbers, the flat file has to be set up with space for each possible number (home, work, cell, pager, etc). (Unlike what the original answer said) you can set up basic links between flat files (e.g. on an employee id), but flatfile databases are not set up for working with multiple files at once.

What are the characteristics of relational table?
Relational tables are structured data representations, consisting of rows and columns where each row represents a unique record and each column represents a different attribute or field.

Relational databases ensure data integrity through constraints and support operations like querying and joining tables to retrieve or manipulate data efficiently.
What is a flat-table database?
A flat-table database is one that uses a single table to store all relevant data. By contrast, a relational database uses several tables to store relevant data, and then establishes 'relations' between them using unique identifiers ... such as primary keys and foreign keys. Flat-table databases are ok if the data is not too complex or repetitive. Relational databases are good when the data is complex and repetative. For example: Keeping track of a personal music CD collection - if one is lazy - can simply be done in a flat-table database table (or a spread sheet). It can also be done in a relational database by creating a few tables and relating them. One table can be artist (with a primary key), another table can be album (relates to a single artist primary key), and a third can be a record label table (which can relate to many artist primary keys). This is a very high-level view of the differences. I .
