Enhanced ER Model

The enhanced ER model is an abbreviation for Enhanced Entity-Relationship (EER) model. As you know, the entity-relationship (ER) model is a pictorial illustration of the relationship between various entities of a domain. In the case of a large amount of data with multiple interrelated entities, the ER diagrams become complex and tough to interpret. For such cases, the need for enhancement in the ER model was observed, and thus, the EER model was designed.

Consider the case of calculating the price of all the products in an customer order. A sequence diagram can provide the information starting from the method “calculating_ the_price”. Hint: - define the objects that are needed so that starting from an order (initial object) to find out the prices of the items and then the total. - starting from an instance of the order define the messages that are passed between the objects in that use case. Example: from the order the messages: get_quantity , get_item are sent to the next object (order_line). - after that there are other sequence messages for the prices (get_prices). - after having done that for all the items the order needs to compute an overall discount (compute_discount). - the method: get_discount_info is invoked and the discount is sent to the customer.

Correct answer will be upvoted else downvoted. Computer science. Child Ehab has a piece of Cut and Stick with an exhibit an of length n composed on it. He intends to snatch some scissors and do the accompanying to it: pick a reach (l,r) and cut out each component al, al+1, ..., ar in this reach; stick a portion of the components together in a similar request they were in the exhibit; end up with different pieces, where each piece contains a portion of the components and each component has a place with some piece. All the more officially, he segments the arrangement al, al+1, ..., ar into aftereffects. He thinks a dividing is lovely if for each piece (aftereffect) it holds that, assuming it has length x, no worth happens rigorously more than ⌈x2⌉ times in it. He didn't pick a reach yet, so he's pondering: for q ranges (l,r), what is the base number of pieces he really wants to parcel the components al, al+1, ..., ar into with the goal that the dividing is delightful.…

The Leader-Member Exchange (LMX) Theory and the Path-Goal Theory are the two separate schools of thought that may be considered in this context. Using examples from real life helps explain things in a way that is both clearer and more believable.
