This post will go through some of the most important C_CPE_13 – SAP Certified Development Associate interview questions that will help you get started with C_CPE_13 – SAP Certified Development Associate.

1. What is the significance of OData services in C_CPE_13 – SAP Certified Development Associate?

OData (Open Data Protocol), a Microsoft-initiated protocol that permits the establishment of REST APIs that connect services, was launched in 2007. The Microsoft Open Specification Promise is the foundation for OData versions 1.0, 2.0, and 3.0. The Open Data Protocol is a computer standard that allows creating and consuming queryable APIs across many providers easier and more interoperable.

2. Could you please describe how SAP OData works?

SAP OData is a standard Web protocol for querying and updating data in SAP. It uses Web technologies like HTTP to give access to data from a wide range of external applications, platforms, and devices. The SEGW transaction in SAP is use to construct the SAP OData service.

3. Could you explain the benefits of OData in SAP?

You can use typical web protocols like GET, PUT, POST, DELETE, and QUERY with OData. OData uses a stateless application design as well. This means that each OData call is treated as a separate request, and data from prior queries is not store. HTTP, URI templates, and JSON are all online standards that use the protocol. It can do CRUD tasks as well as run stateless apps.

4. What are some of SAP OData’s drawbacks in C_CPE_13 – SAP Certified Development Associate?

Odata has the drawback of not providing direct access to the backed dictionary objects. Instead, developers can only use remote access to access the item. You must use system-provided programming APIs to access Odata service development. These APIs make use of remote objects, which means you don’t have access to the database or directory objects themselves.

5. What does Association OData mean to you?

Through affiliations, entities can be link to one another. Foreign key restrictions between database tables or hierarchies, as well as other relational links between database objects, are similar to these associations.

6. What is the distinction between OData association and navigation?

Users can utilise OData to construct Entity Type associations, which can then be use in Navigation Paths. Users can utilise Navigation Paths to get from one side of an association to the other.

7. What is the difference between Association and Association set?

A logical confinement method for association instances of the same type is an association set. Because associations do not specify the structure of data or relationships, they are not a valid data modelling construct.

8. How would you explain SAP SQLScript to someone who isn’t familiar with it?

The Structured Query Language (SQL) is a programming language for databases. The SQLScript extension to SQL allows you to define data types without having to create associated tables. SQLScript is a set of extensions that allow you to create table definitions, data manipulation statements, and data constraint statements.

9. What SQL support does SAP HANA provide?

Many SQL queries are support by the SAP HANA database for system management, object creation and storage, and data manipulation. When using the SAP HANA database, there are some constraints. To correct those issues, you must first determine their numerical error code.

10. In SQL Server, what is a scalar-valued function?

A scalar-valued function, as opposed to an array or other collection, returns a single value. Next, it can take one or more arguments and perform some sort of task using them. It can be applied to any form of data in a variable. It has no parameters and can be use everywhere a single value is required, such as an argument or a return value from a function.

11. Could you describe a table function in SQL?

A user-define function that delivers results in the form of a table is known as a table-value function. A table is always the type of table-valued function. As a result, you may utilize a table-valued function in the same way that you would another table.

12. Can you tell the difference between scalar and table-valued functions?

Single scalar data values of a pre-define type are return by scalar-valued functions. Scalar-valued functions cannot reference tables or other structures in their RETURN statements, unlike inline table-valued functions, which conduct computations based on one or more statements.

13. How would you define triggers as a C_CPE_13?

Database triggers are programs that run when an INSERT, UPDATE, or DELETE statement is issue. Triggers can be assign to a table or specific columns, and they can contain several SQL queries. You must assign a trigger to a table or an action such as INSERT, UPDATE, or DELETE once it has been define.

14. Can processes be called from within triggers?

We may certainly call a saved method from within the trigger. Create PROCEDURE [dbo], for example.

15. What distinguishes a stored process from a trigger?

User-defined SQL code such as store procedures and triggers can be called directly by the user. Stored procedures are SQL statements written in a local language, usually PL/SQL, that return a value and can be called explicitly. Triggers, on the other hand, are functions that run automatic code when certain actions (such as update, insert, or delete) occur.

16. What are the purposes of triggers?

When an event or scenario occurs, a TRIGGER function triggers an action. It obtains information about the event, subevent, or name of the object or analytic workspace that prompted a trigger programme (a TRIGGER DEFINE, TRIGGER AFTER UPDATE, or TRIGGER BEFORE UPDATE program) to be execute.

17. Can you inform me about the SAP HANA calculation view as a C_CPE_13 expert?

SAP HANA calculation views are basic yet powerful information views that are similar to both attribute views and analytical views and may be use to construct more advanced slices on the data available in the SAP HANA database. They also provide additional analytic services.

18. In Hana, what’s the difference between the calculation and analytical views?

Analytic views are use to model data with metrics and complicated logic spread over numerous tables. Advanced inquiries on the data in the SAP HANA database can be generate using calculation views, which can be use to process complex questions.

19. What are the many sorts of computation views available?

• A graphical editor is use to construct graphical computation views.
• Calculation views base on SQL scripts: these are built by creating SQL scripts.

20. How would you define the server-side JavaScript provided by Nodejs?

Node. js is a JavaScript implementation that allows you to use JavaScript to write server-side programming. It enables you to write and run tiny programmes from the command line without the use of a browser. A node, for example, can run a hello programme written in a file as if it were a CGI script running on your web server.

21. What JavaScript is referred to as “server-side JavaScript”?

Server-side JavaScript, or LiveWire, is an application development environment that uses JavaScript to create server-based applications. JavaScript is a scripting language that may be use to generate both web pages and server-side programs. Livewire is a JavaScript IDE that allows you to construct server-side apps using JavaScript.

22. Do you know how to tell the difference between JavaScript and jQuery?

JavaScript is a client-side programming language, whereas jQuery is a JavaScript-based library. AJAX is a web development method that allows elements of the user interface to be update without requiring a page reload.

23. How can you debug a node js application in the easiest way possible?

Activate the Node Inspector pane, then select the Debugger tab before pressing the Start button. With a Variables, Watch, Call Stack, Loaded Scripts, and Breakpoints list, the debugging interface is identical to Chrome’s DevTools.

24. Could you explain the persistent data model to me?

When a data structure is update, a persistent data structure always saves the prior version of itself. A persistent data structure, unlike a regular data structure, which is changed in place, makes new versions of itself every time it is update. It can last for a short time or for a long time.

25. What is the framework for UI integration in C_CPE_13 – SAP Certified Development Associate?

You can navigate from a system application user interface to an external application user interface using the ADF Integration framework. In a variety of ways, you can define the context of navigation and develop an integrated user experience.

26. What is the purpose of “Git” as a source code management tool?

Git is the most widely use software for managing source code versions. It can be use to track many versions of a file at the same time.

27. Could you describe how database security is use in C_CPE_13 – SAP Certified Development Associate?

Database security measures are intend to safeguard not only the database’s data, but also any applications that access it, from unauthorise access, harm, and intrusion. Database security software protects your data, the management system that stores it, and any applications that access it from unauthorize access, harm, and intrusion.

28. What are the five most important stages in ensuring database security?

The following are the five most important database security practices:

• To begin, use a database proxy to guard against any attacks.
• Second, set up auditing as well as a robust logging system.
• After that, adhere to a strict user account management policy.
• Updating the database software and the operating system
• Finally, any sensitive data in your app, both in transit and at rest, should be encrypte.

29. How would you define the term “authorization” in the context of a database?

The process of delivering information about the authenticate user to the database manager is known as authorization. This information is use by the database manager to determine which database operations and data items a user is allow to access.

30. Could you explain the application security tools to me?

The information-based economy of today necessitates the protection of an organization’s software applications from external threats throughout the application lifecycle. To meet this demand, a new class of information security technologies known as application security products has arisen.

Program security tools are use to safeguard software applications and data throughout the lifecycle of the application. These tools can guard against data theft, unlawful access, and other types of harmful activity.
