Unit Testing

Unit Testing: -
After completion of design & their reviews, the programmers start coding.
In this phase, the programmers prepare programs & then test each program using
White Box Testing Techniques.
There are 4 White Box Testing Techniques:
1.Basis Path Testing
2.Control Structure testing
3.Program technique Testing
4.Mutation Testing
These Techniques are applicable only for Programs.
1.Basis Path Testing:
During this test the programmers concentrate on the execution of
programs without any runtime errors. To conduct this test, the corresponding
programmer follows the below approach.
Write a program with respect to LLD (Low Level Design)
Draw a flow graph for that program.
Calculate cyclomatic complexity.
Runt that program more than one time to cover all executable areas.



One should run the above program 2 times to cover all executable
areas. A programmer gets confidence that a program is running only when the
cyclomatic complexity is reached in running the programs designed.
NOTE: The above program should be run 2 times
° One time to check whether if condition is satisfied or not
° Next time to check whether the else condition is satisfied or
not, without any runtime errors.

Handling of Skew

Handling of Skew ô€‚„ The distribution of tuples to disks may be skewed — that is, some disks have many tuples, while others may have fewer tuples. ô€‚„ Types of skew: ô€ƒŒ Attribute-value skew. ô€‚¾ Some values appear in the partitioning attributes of many tuples; all the tuples with the same value for the partitioning attribute end up in the same partition. ô€‚¾ Can occur with range-partitioning and hash-partitioning. ô€ƒŒ Partition skew. ô€‚¾ With range-partitioning, badly chosen partition vector may assign too many tuples to some partitions and too few to others. ô€‚¾ Less likely with hash-partitioning if a good hash-function is chosen. Handling Skew in Range-Partitioning ô€‚„ To create a balanced partitioning vector (assuming partitioning attribute forms a key of the relation): ô€ƒŒ Sort the relation on the partitioning attribute. ô€ƒŒ Construct the partition vector by scanning the relation in sorted order as follows. ô€‚¾ After every 1/nth of the relation has been read, the value...

Fragment-and-Replicate Join

Fragment-and-Replicate Join ô€‚„ Partitioning not possible for some join conditions ô€ƒŒ e.g., non-equijoin conditions, such as r.A > s.B. ô€‚„ For joins were partitioning is not applicable, parallelization can be accomplished by fragment and replicate technique ô€ƒŒ Depicted on next slide ô€‚„ Special case – asymmetric fragment-and-replicate: ô€ƒŒ One of the relations, say r, is partitioned; any partitioning technique can be used. ô€ƒŒ The other relation, s, is replicated across all the processors. ô€ƒŒ Processor Pi then locally computes the join of ri with all of s using any join technique. ô€‚„ General case: reduces the sizes of the relations at each processor. ô€ƒŒ r is partitioned into n partitions,r0, r1, ..., r n-1;s is partitioned into m partitions, s0, s1, ..., sm-1. ô€ƒŒ Any partitioning technique may be used. ô€ƒŒ There must be at least m * n processors. ô€ƒŒ Label the processors as ô€ƒŒ P0,0, P0,1, ..., P0,m-1, P1,0, ..., Pn-1m-1. ô€ƒŒ Pi,j computes the join of ri with sj.

USER INTERFACE DESIGN FOR ANNA UNIVERSITY SYLLABUS

Unit – I Introduction Objective To Understand the definition and importance of User Interface Design To know about the concept, advantages and applications of GUI and Web interface User Interface Design Definition • User interface design is a subset of a field of study called human-computer interaction (HCI). Human-computer interaction is the study, planning, and design of how people and computers work together so that a person’s needs are satisfied in the most effective way. • The user interface is the part of a computer and its software that people can see, hear, touch, talk to, or otherwise understand or direct. The user interface has essentially two components: input and output. • Input is how people communicate his needs to the system using keyboard or any pointing device and output is how the system returns processing result to user through screen or sound. • The best interface is one which has proper design with combination of effective input and output mechanisms. Importance of...
