In M2M communication, such as with the Internet of Things trend, the M stands for ______.

________ can be linear, curved, or follow a predetermined shape

Fill in the blank(s) with correct word

Consider the following database schema. The attributes are ABCDEGHKLM (10 in total). The FDs are:

1. ABE -> CK 2. AB -> D 3. C -> BE 4. EG -> DHK 5. D -> L 6. DL -> EK 7. KL -> DM (a) Compute the attribute closure of EGL with respect to the above set of FDs. Show all steps. (b) Compute the minimal cover of the above set of FDs. Show all steps. (c) Use the 3NF synthesis algorithm to construct a lossless, dependency preserving decomposition of the above schema. Show all steps. (d) Are all the schemas in the resulting decomposition in BCNF? If yes, then you are done. If there are schemas that are not in BCNF, decompose them further to achieve BCNF. Is the resulting decomposition dependency-preserving? Yes/no answers do not count. Explain everything.
