2. What is a data processing cycle and what is its significance ?
Answer:
Data often needs to be processed continuously and it is used at the same time. It is known as data processing cycle. The same provide results which are quick or may take extra time depending on the type, size and nature of data. This is boosting the complexity in this approach and thus there is a need of methods that are reliable and advanced than existing approaches. The data cycle simply make sure that complexity can be avoided upto the possible extent and without doing much.

3. Suppose we assign you a new project. What would be your initial point and the key steps that you follow ?
Answer:
The first thing that largely matters is defining the objective of the task and then engages the team in it. This provides a solid direction for the accomplishment of the task. This is important when one is working on a set of data which is completely unique or fresh. After this, next big thing that needs attention is effective data modeling. This includes finding the missing values and data validation. Last thing is to track the results.

4. What do you mean by the term data warehousing? Is it different from Data Mining ?
Answer:
Many times there is a need to have data retrieval, warehousing can simply be considered to assure the same without affecting the efficiency of operational systems. It simply supports decision support and always works in addition to the business applications and Customer Relationship Management and warehouse architecture. Data mining is closely related to this approach. It assures simple findings of required operators from the warehouse.

5. Have you ever encountered an error called “depth not equal” ?
Answer:
When two components are linked together if their layout does not match then this problem can occur during the compilation of the graph. A solution to this problem would be to use a partitioning component in between if there was change in layout.

8. Can anyone give me an exaple of realtime start script in the graph ?
Answer:
Here is a simple example to use a start script in a graph:
In start script lets give as:
export $DT=`date ‘+%m%d%y’`
Now this variable DT will have today’s date before the graph is run.
Now somewhere in the graph transform we can use this variable as;
out.process_dt::$DT;
which provides the value from the shell.

11. Describe in detail about lookup ?
Answer:
A group of keyed dataset is said called lookup. The datasets in lookup can be classified into two types such as Static and Dynamic. In the case of dynamic datasets, the lookup file would be generated in the previous phase and used in the current phase. With respect to the data present in a particular multi/serial file, lookup can be used to map values.

19. What would be the next step after collecting the data ?
Answer:
Once the data is collected, the next important task is to enter it in the concerned machine or system. Well, gone are those days when storage depends on papers. In the present time, data size is very large and it needs to be performed in a reliable manner. The digital approach is a god option for this as it simply let users perform this task easily and in fact without compromising with anything. A large set of operations then need to be performed for the meaningful analysis. In many cases, conversion also largely matters and users are always free to consider the outcomes which best meet their expectations.

21. How scientific data processing is different from commercial data processing ?
Answer:
Scientific data processing simply means data with great amount of computation i.e. arithmetic operations. In this, a limited amount of data is provided as input and a bulk data is there at the outcome. On the other hand commercial data processing is different. In this, the outcome is limited as compare to the input data. The computational operations are limited in commercial data processing.

The first is Collection and second one is preparation of data. Of course, the collection is the first stage and preparation is the second in a cycle dealing with data processing. The first stage provides baseline to the second and the success and simplicity of the first depends on how accurately the first has been accomplished. Preparation is mainly the manipulation of important data. Collection break data sets while Preparation joins them together.

24. Do you know what a local lookup is ?
Answer:
If your lookup file is a multifile and partioned/sorted on a particular key then local lookup function can be used ahead of lookup function call. This is local to a particular partition depending on the key.
Lookup File consists of data records which can be held in main memory. This makes the transform function to retrieve the records much faster than retrieving from disk. It allows the transform component to process the data records of multiple files fast.

1) If it is not already displayed, display the Transform Editor Grid.
2) Click the Business Rules tab if it is not already displayed.
3) Select Edit > Add Default Rules.

Answer:
Well, it actually depends on the type and nature of data. Although it is possible to accomplish both these tasks through the same software, many software have their own specialization and it would be good if one adopts such an approach to get the quality outcomes. There are also some pre-defined set of modules and operations that largely matters. If the conditions imposed by them are met, users can perform multiple tasks with the similar software. The output file is provided in the various formats.
