Consider the following ER diagram and answer the following questions. Please only answer the questions (short and simple) to understand. a. List the strong (nonweak) entity types in the ER diagram. b. Is there a weak entity type? If so, give its name, partial key and identifying relationship c. What constraints (in terms of relationships) do the partial key and the identifying relationship of the weak entity type specify in this diagram? d. List the name of all the relationship types, and specify the (min, max) constraint on each participation of an entity type in a relationship type. Justify your choices.RegionName CharName MaxHitPoints Level MaxMana AcctName Password LastPlayed ExpPoints CurrHitPoints 0000 RegionName Climate Precipitation Foliage Created On Туре CurrMana Playersin LastSigned On SbscrbrName Account Has Character Contains Region SbscrbrAddress SbscrbrEMail SbscrbrPhone Carrying AcctCreated On ItemName CreepName IDNum RanInto Item Instantiation IsType Item Modifier Item Type WhenCreated ItemDamage Carrying HitPoints Creep IsType Creep Instantiation n Contains Mana IDNum Attack

Formal approaches are based on the use of logical reasoning. In terms of general popularity, propositional logic and predicate logic are your best bets. An undergraduate student in discrete mathematics wonders whether propositional and predicate logics may be useful in software testing. This student really needs your help in finding what they're looking for. The benefits and drawbacks of logic as a tool for software testing might be outlined as one such approach. How should formal programme verification be performed, and which logic is optimal for doing so?
