Cooking Channel Database System
Food is one of human beings’ favorite obsessions. Most people spend a great deal of time physically and mentally preoccupied with food: we organize and prepare meals, we daydream about what’s for lunch or dinner; we eat.
"We are What We Eat"
As food is a major part of every one’s life so cooking channels are getting so much popularity nowadays. Cooking Channels are television specialty channels that only on air programs about food and cooking.
A number of cooking shows have run for many seasons on channels. Many of the more popular cooking shows have had flamboyant hosts whose unique personalities have made them into celebrities. From recent past, famous chefs are hosting the shows. The organization keeps the records of these shows, name, producer, timing etc along with the detailed information about the hosts. Administrator has full rights on this data as he/she is responsible for maintaining the system.
The channels also store the cooking recipes categories wise. There are categories like Breakfast, Salad Entrees, Soups, Fish, Chicken, Meat, Vegetarian Entrees, Side Salad/Dressings, Side Vegetables, and Desserts. Chefs can enter/edit/delete the recipes. Viewers can view these recipes any time through website. Viewers can also enter their own recipes along with their own record. They can also comment on the recipes of chefs and other people and on shows of the channel. All the users have to register themselves to access the system.
Mr. X wants to open a new cooking channel and has approached you to create a system to store the whole data related to cooking shows and recipes.

idea ye hy k ap ne agar vu k lecture sun liye to sir sk ki videos dekhen youtube pe, to clear the concepts, aor sath me handouts se consult karen
jis se apko
entities identify karna aa jayga,
phir relation aor cardinality check karen among entities,
phir dependency dekhen, apply normalization rules if u know 1nf, 2nf,3nf. but not necessory for this assignment actually,
end pe apko pure diagram mily ge,
ap ne jo pic share ki, is se generlization ka concept mily ga apko, super type aor subtype se,
what about administrator and channel. i think these two should not be in erd.
acha us diagram mae entities thik thi ya kuch skip karni hai
sk bro check it er diagram is right or not?
what about administrator and channel. i think these two should not be in erd. and you have not decribed relation type and also use crow's feet notation for cardinality
diamond shape may relation ka name bhe likhna hay
if put relation name in diamond that is called "Associative Entity" and we use associative entity only if we hav common attributed which needed in both relations.
