|Can adapt changes.||Cannot adapt to changes.|
2.In the PeopleSoft Data Management system, what exactly is the KNN imputation method?
It is basically an approach to deal with the missing values of the attributes. This is done by assigning the values that are similar to the attribute which is missing. The similarity is generally determined with the help of a distance function.
3.How can you say that data is an available resource for an organization?
In the present-day business models, most of the tasks that are accomplished found their source for the relevant information through the data collected randomly. It’s nothing but the data which lets the organization’s device information required to make decisions or to come with new plans. Effective management of data always makes sure of all the information remains available anytime it is required. Also, managing the data simply makes sure of all the tasks to accomplish in a rightful and in fact, delightful manner in an organization.
4.What is the concept of Querying?
While managing the data, there is often a need to perform some tasks in a defined sequence. Thus, the data is scheduled according to and groups and the functions are managed in a defined sequence. This process is known as querying.
5.What are the skills that one must have to handle responsibilities related to data management according to you?
The first thing is to have all the required knowledge on the reporting packages, databases, and programming languages. In addition to this, strong skills are required for analyzing, collecting, monitoring, as well as assembling the data. Good technical knowledge and skills in handling the statistical packages are also required for effective data management.
6.How can data be managed with the help of the PeopleSoft Data Management approach?
There are certain things that the user should be careful about and pay extreme attention to. The first thing to do to effectively manage the data is to define the problem first in a proper manner in case the same declare its presence. Next is to make sure that the data should be explored in a way that all the modules are defined within the structure. After this, the next step to consider is the preparation of the data in a reliable manner. Modeling is done after this and data validation is to be considered and implementation is done after the same.
7.Tell something you know about data cleansing and why it is important?
Data Cleansing is nothing but making data free from all sorts of bugs and errors. This is done to assure that the information is authenticated and there are no inconsistencies that can cause issues at a later stage. In short, it is an approach to enhance the quality of the data.
8.According to you, what are some of the best practices that should be followed when it comes to making data totally free from errors?
- First and the foremost is sorting the data through the available options of attributing.
- The data is to improve at every step of its use so that the quality can be enhanced significantly.
- It would be good for the users to make sure that the large datasets are broken into smaller ones. This often helps to avoid a lot of errors that are generally ignored.
- A set of utility functions is to be created for the effective elimination of bugs.
- A close eye is to be kept on all the operations performed by the users for cleaning the data.
9.Can you tell me something about the logistic regression?
Basically, it is an approach that is useful for properly analyzing or examining a dataset having multiple independent variables in it.
10.What is Data Mining and how it is different it from data profiling?
It is basically an approach that is considered when it comes to detecting the records which are not usual, detecting the dependencies, and defining as well as finding the relations that bind several attributes together. On the other side, Data profiling is an approach that targets the analytics of the attributes. Very useful information on the range of the attributes, frequency, as well as occurrence, can be defined through it.
11.What are the common issues that you can face while working with the PeopleSoft Data management approach?
- Problems related to misspellings of the words.
- Double entries of the same information of data in the system.
- Representation of varying values in an improper manner.
- Values that are not justified or are illegal.

14.Suppose while handling the data management tasks, it is reported to you that some files are missing, what would be your plan of action?
The first thing that can be done is to prepare a validation report simply. It generally provides information on the suspected data in a reliable manner. The good thing is it briefly defines the validation criteria of everything and the true reason for the occurrence of the errors. The suspicious data is to be determined in terms of the acceptability of the same. The data which seems to be invalid should be replaced with immediate effect with the help of a violation code.
15.Name a few properties of the clustering algorithm?
Flat, Iterative, Disjunctive, Hard and soft.
16.What do you know about structured and unstructured data?
Structured data is the one where everything is present in a defined sequence and thus locating the same is not at all a big deal. This data is generally limited in terms of size. Also, the structured data help to save a lot of time. On the other hand, unstructured data is the one in which everything is not managed in the way it has to be. It is a random collection of information and it’s not necessary that the source of the same is defined always. Unstructured data is often bulky and needs a lot of attention and time for the users when it comes to deriving something important from the same.
17.What exactly do you know about multi-source problems?
- Restructuring of schemas especially if they are integrated.
- Identification of the similar records and then merging them into a single record that contains the information on the redundancy, as well as on the attributes.
Multi-source problems are the ones that declare their presence because of reasons that are not limited to a specific source. In other words, they can arrive due to multiple reasons and it is not always necessary that they can be avoided with simple methods. In order to avoid them, the users need to make sure of the following:-
18.What exactly do you know about an outlier? Name the types used mainly.

19.Tell something you know about the Map-Reduce approach?
It is basically an approach that is considered for the purpose of processing the data sets which are large in size and then splitting them into subsets. It is not always necessary that all the subsets are processed on the same server.
20.Tell something about the hierarchical Clustering Algorithm and why it is important in data management?
When it comes to integrating the groups that already exist or dividing them into subgroups, this algorithm is considered. It is good in enabling the data experts to perform their tasks reliably.
21.Among predictive modeling and Advanced Analytics, which one is better and why?
Obviously, the Advanced Analysis is better. This is mainly because in the first case, the things or the tasks are managed based on predictions. Although the same is made by data experts, there are chances of occurrence of errors in the same. The advanced analysis makes sure that data is good enough to be considered for the different tasks or for processing further.
22.Tell something about collaborative filtering and how it can be trusted?
It is basically a simple algorithm in data management that is considered for the purpose of creating a recommendation system that decides and analysis the behavior of the data.

In default processing, any blank fields in the component are set to their default value. You can specify the default value either in the Record Field Properties, or in FieldDefault PeopleCode.
76.What is the difference between field default and Rowinit?
|Field default specifies only the default value for a field when we are in Add mode.||Row init fires only when a row of data coming from database to component buffer.|
77.What is the use of primary permission list in user profile?
Primary permission list is used for mass change and definition security purposes.
78.How to authorize the user to run a process or report?
To authorize a user to run a process, the process group, which contains the process or report, should be added to the permission list of that user.
79.How to give access to the records that are to be used in a query?
To give access to the records that are to be used in query, we have create a new query security tree and add the records which we want to give the access and then assign a access group to the tree. After that we have to add that query tree and query access group to the permission list.
80.What are the rules used by the system to determine whether a user is authorized to update an object?
The user should have the permission to update the object. This is given by the Definition security. The group, which holds the object, should be added to the permission list of the user in update mode.
81.What is Dynamic View?
Dynamic view that can be used like a view in pages and PeopleCode, but is not actually stored as a SQL view in the database. Instead, the system uses the view text as a base for the SQL Select that is performed at runtime.Dynamic views can provide superior performance in some situations, such as search records and in PeopleCode Selects, because they are optimized more efficiently than normal SQL views.
82.What is Application Engine?
It is the tool, which performs, background SQL processing against our application data tables. It is an alternative for COBOL, SQL or SQR.
83.Does the search record for a panel have to be the same as the record being accessed on the panel? Why or Why not?
The search record for the panel does not have to be the same as the record being accessed on the panel because the search record is used to search for and or Filter the search key.
84.Differentiate Error V/s Warning statements in People code?
