**1: Explain SAS and its functions.**

**Answer: **

SAS is a popular Statistical Analysis System used for data analytics. It contains a set of software tools that are well integrated to extract, compile and process the data including Big Data. SAS performs the following functions:

a) Data Warehousing

b) Statistical scrutiny of the information, data mining and metrics

c) Helps the businesses in planning and forecasting

d) Provides statistical data for decision-making

e) Retrieving and managing useful business information

f) Presenting the available information as reports and graphics

g) Process research and Project management

h) Improving Quality by providing valuable insights

i) Application Development

**106: While performing one-to-one reading does the resulting Data Set contain all the observations and variables from the input Data Sets?**

**Answer: **

While performing one-to-one reading, the resulting Data Set has all the variables from the input Data Sets. If the input Data Sets have variables with the same name, then the data from the Data Set which was read last overrides the data which was read earlier. The number of observations will be the same as the number of observations in the smallest Data Set.

**107: What is the maximum number of Data Sets which can be given as an input for APPEND procedure?**

**Answer: **

While using APPEND procedure, only two Data Sets can be combined at a time.

**139: What is the default length which SCAN function assigns to the target variable?**

**Answer: **

SCAN function assigns a length of 200 to each target variable.

**192: How does SAS store date and time and what is the advantage?**

**Answer: **

SAS stores date and time as numeric values. SAS date value is counted as number of days from Jan1, 1960 to the given date. When a SAS INFORMAT is used to read a date, SAS converts it into a numeric value. A SAS time value is counted as number of seconds since midnight. The greatest advantage of storing date and time as numeric value is that they can be used in numeric calculations just like any other numeric variable. This feature is not available in most of the programming languages.
