The data builder enables analysts and data administrators to perform basic data preparation.
                  You can create 
data queries to perform joins, add 
calculated columns, and 
subset and sort data. Several productivity features accelerate the creation of columns based
                  on common aggregation functions.
                  
               
 
               
               Once you create your data queries, you can reuse them as subqueries for more sophisticated
                  data 
queries, export them as jobs for scheduling, or schedule them directly from the 
user interface.
                  
               
 
               
               The data builder has self-service data import features that enable you to access data
                  from the following 
data sources: 
                  
                  
                     
                     
                        
                        - 
                           
                           
                           
                        
 
                        
                        - 
                           
                           
                           
                        
 
                        
                        - 
                           
                           
                           
                        
 
                        
                        - 
                           
                           
                           
                        
 
                        
                        - 
                           
                           
                              
                              Facebook, Google Analytics, and
                                 Twitter
                                 
                              
                              
                            
                           
                         
                        
                     
                     
                   After you import the data, you can prepare it for
                  analysis or join it with existing data.
                  
               
 
               
               The
                  data builder provides a series of features that take advantage of
                  the in-memory tables in SAS LASR Analytic Server.
                  
                  
                  
You can perform the
                     following operations to add data to memory in the server:
                     
                  
                  
                  
                     
                     
                        
                        - 
                           
                           
                              
                              load an existing table directly
                                 into memory
                                 
                              
                              
                            
                           
                         
                        
                        - 
                           
                           
                              
                              load the results of a 
data query into memory (or stage the data and then load it into memory)
                                 
                              
 
                              
                            
                           
                         
                        
                        - 
                           
                           
                              
                              append rows to an in-memory table
                                 
                              
 
                              
                            
                           
                         
                        
                     
                     
                   
                  
                  
                  After the data is in
                     memory, you can perform the following operations with in-memory tables:
                     
                  
                  
                  
                     
                     
                        
                        - 
                           
                           
                              
                              join in-memory tables to form a
                                 LASR star schema
                                 
                              
                              
                            
                           
                         
                        
                        - 
                           
                           
                              
                              append entire in-memory tables to another in-memory table
                              
                            
                           
                         
                        
                        - 
                           
                           
                              
                              save in-memory tables to HDFS for persistence and fast
