But please may I know how am I supposed to know when table’s primary key / foreign key do not match and doesn’t show any relationship in ERD as below. But when I extracted the ERD diagram of CT_Loc and CT_ Hospital they do not have any relationship and when I used the...
If we add primary key attributes to the weak entity set, they will be present in both the entity set and the relationship set and they have to be the same. iii. Hence, there will be redundancy in the ER diagram and we lose the concept of dependency. iv. In the example mentioned abov...

We also identified a lack of trials of cluster randomisation. Although these may be more complex in design, if accounted for all key factors including clustering effect, appropriate sampling and analyses, cluster RCTs could add important value to the current evidence. ...
Second, LTE-PW/Wi-Fi First must be implemented on the key components of the telecommunications infrastructure in parallel to a Wi-Fi First solution so that via control of the Framework SIM a switch to operations as a hard SIM may be automatically enabled. This differs from RFC 5944 and its...
