The data _____ component of a database management system (DBMS) is used to create and maintain the data dictionary. manipulation

Ira Lisetskai [31]

Answer:

definition

Explanation:

A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.

A data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.

In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores.

This ultimately implies that, a data dictionary found in a computer database system typically contains the records about all the data elements (objects) such as data relationships with other elements, ownership, type, size, primary keys etc. This records are stored and communicated to other data when required or needed.

Basically, when a database management system (DBMS) receives data update requests from application programs, it simply instructs the operating system installed on a server to provide the requested data or informations.

Hence, the data definition component of a database management system (DBMS) is used to create and maintain the data dictionary.

In addition to the obvious temptations in Berkilak's castle with his wife (all of which involve erotic temptation and the temptation to violate hospitality for personal pleasure), more significant spiritual temptations frame this story. First, Gawain displays an element of pride when he agrees to participate in the initial contest. While Arthur is more to blame and Gawain offers to take his place, it certainly is not prudent to participate in this contest with a character whose appearance suggests that he is not a normal, mortal man. The first part of this bargain therefore involves the temptation of pride.

Later, the temptation that most condemns Gawain is the desire to continue living even if one will live a life compromised by deceit. While it is understandable that Gawain would hide the garter and flinch at the blow of an ax, the temptation to focus on his mortal rather than his spiritual life is the cause of his wearing the garter as a mark of shame.

It takes 2 seconds to read or write one block from/to disk and it also takes 1 second of CPU time to merge one block of records.

Alexxx [7]

Answer:

Part a: For optimal 4-way merging, initiate with one dummy run of size 0 and merge this with the 3 smallest runs. Than merge the result to the remaining 3 runs to get a merged run of length 6000 records.

Part b: The optimal 4-way merging takes about 249 seconds.

Explanation:

The complete question is missing while searching for the question online, a similar question is found which is solved as below:

Part a

For optimal 4-way merging, we need one dummy run with size 0.

Merge 4 runs with size 0, 500, 800, and 1000 to produce a run with a run length of 2300. The new run length is calculated as follows $L_{mrg}=L_0+L_1+L_2+L_3=0+500+800+1000=2300$
Merge the run as made in step 1 with the remaining 3 runs bearing length 1000, 1200, 1500. The merged run length is 6000 and is calculated as follows
