To load information on data human user must create first the Can the same table be sorted on data in two different columns? What sort of files have to be frequently edited by the database management server administrator (by the DBA)? Can we have database on a paper? What can DAB do with tables that spreadsheet program cannot easily do? What is traditionally widely used data format used (file format) when data are exported from one database and imported into another database?Explanation / Answer
2.
a) Paper or papyrus sheets are very light in wait, single layered rectangular shapes in which data can be written using inks or pencils. When they are used, a large amount of data can be written on the papers. They are even easy to carry from one place to other place and it can be easily stored in one place or the other.
When it comes to stone plate, it is difficult to write the data to store but it can last forever. Huge amount of data cannot be written easily and it cannot be carried to one place to other.
Thus, paper/papyrus sheets are having more advantage as storage media.
b)
The major algorithm is used to implement in the Herman Hollerith tabulator mechanical computing device is,
To generate holes in the punch card to represent the data and then read the punch cards in-order to process the data through the holes on the punch card.
The mechanism is developed by using the electrical connections to trigger a counter and records the information while punching the card.
Now the data will be encoded by the locating the holes in the card. In present days, the locations of the holes on the card are known as rows and columns.
These are majorly used in 1890 U.S. Census data.

a)
The original founder of IBM is Charles Ranlett Flint. Herman Hollerith’s laid the foundation for IBM.
b)
The first business application of the Herman Hollerith’s tabulator machine was punch card that computes the census process. Before the usage of this machine people used to count the data for decades. After the usage of the machine, they used to count with in two and half years.
4.
a)
Applications like, text processing, developing, deploying, and web-centric applications are most likely to reuse the DBMS software. In other words, in software development phase the DBMS software is reused.
b)
To load information on data human user must create first the data.
5.
a)
Yes, the same table can be used to sort the data in two different columns.
Example: authors(a_firstName, a_lastName, city, state, bookName)
Query:
Select a_firstName, a_lastName, city, state
From authors
ORDERED BY a_lastName ASC, city DESC;
b)
Most of the times, the DBA (Data Base Administrator) edits the log files, upgradation of data files at the end of the data and maintains the backup files.
6.
a)
No, we can’t have database on a paper because the data stored in the paper will get corrupted easily and also it is difficult to connect to the library.
b)
In a spreadsheet, each defined value will contain a relation with other values. It can be stored with in a system. Most of the spreadsheets are used for calculations.
In a data base, data can be stored in different places and it easy to retrieve information from different tables into a single table. Data base is used as information storage or retrieval system.
