I n an Entity-Relationship (ER) model, suppose 𝑅 is a many-to-one relationship from entity set E1 to entity set E2. Assume that E1 and E2 participate totally in 𝑅 and that the cardinality of E1 is greater than the cardinality of E2. Which one of the following is true about 𝑅?1 AnswerConsider an Entity-Relationship (ER) model -gate-cse-20151 AnswerWhat is entity-relationship model?1 AnswerDefine an entity and an attribute,explain the different types of attributes that occur in an ERdiagram model,with an example Database Management Systems - 10CS54 VTU notes 8 Marks (Dec /Jan 2013, Dec/Jan 2014) 1 AnswerA software model that can’t be used in functional testing (2M) 1 Answer“This life cycle model is basically driven by schedule and budget risks” This statement is best suited for 1 AnswerHow does SQL inplement the entity integrity constraints of relational Data Model?

Take the water density and the acceleration due to gravity as 103 kg/m3 and 10 m/s2, respectively. Assume no losses both in model and prototype turbines. The power (in MW) of a full sized turbine while working under a head of 30 m is _______ (correct to two decimal places).0 Answer
