_____ is a problem-solving technique where each problem in a database is stored with a description and keywords that identify it
babymother [125]

Answer:

Case-based reasoning.

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.

Case-based reasoning is a problem-solving technique where each problem in a database is stored with a description and keywords that identify it. It is typically based on cognitive science and artificial intelligence.

A computer has a cache and main memory. 20 ns are required to reference a word that is in the cache. If the word is in main memo
Alecsey [184]

Answer:

T_{average} =12026ns

Explanation:

Given Information:

T_{cache}=20 ns

T_{main}=60ns

T_{disk} =12ms=12,000,000ns

hit_{cache} =0.9

miss_{cache} =1-0.9=0.10

hit_{main} =0.99

miss_{main} =1-0.99=0.01

There are 3 possible cases

1. Location of reference word is in cache

T_{cache}*hit_{cache} =20*0.9=18ns

2. Location of reference word is not in cache but in main memory

(T_{cache}+T_{main})*(miss_{cache}*hit_{main}) =(20+60)*(0.10*0.99)=7.92ns

3. Location of reference word is neither in cache nor in main memory

(T_{cache}+T_{main}+T_{disk})*(miss_{cache}*miss_{main})

(20+60+12,000,000)*(0.10*0.01)=12000.08 ns

The average time required to access a referenced word on this system is simply the sum of above 3 cases

T_{average} =18+7.92+12000.08=12026ns
