How to Prepare for Infosys SES Interview | HackWithInfy 2021

For instance, two students enrolled in the same university cannot have the same roll number while two students in different universities might have the same roll number. We cannot use these variables in C programming. C does not support it "formally" but it can always be implemented by other methods. What is null pointer? When referring to computer memory, a null pointer is a command used to direct a software program or operating system to an empty location in the computer memory.

Commonly, the null pointer is used to denote the end of a memory search or processing event. In computer programming, a null pointer is a pointer that does not point to any object or function. A nil pointer is a false value.

In the programming language C, NULL is an available command that can be used, where nil is an available command used in the Pascal programming language. What are the 4 basics of OOP? Abstraction, Inheritance, Encapsulation, and Polymorphism. An object-relational database ORD ,or object-relational database management system ORDBMS ,is a database management system DBMS similar to a relational database, but with an object-oriented database model: objects, classes and inheritance are directly supported in database schemas and in the query language.

In addition, just as with proper relational systems, it supports extension of the data model with custom data-types and methods. Structural difference between bitmap and b-tree index? Btree It is made of branch nodes and leaf nodes.

Branch nodes holds prefix key value along with the link to the leaf node. The leaf node in turn contains the indexed value and rowed. Bitmap It simply consists of bits for every single distinct value. It uses a string of bits to quickly locate rows in a table.

Used to index low cardinality columns. The formal definition of database schema is a set of formulas sentences called integrity constraints imposed on a database. Conceptual schema- a map of concepts and their relationships.

Logical schema- a map of entities and their attributes and relations Physical schema- a particular implementation of a logical schema Schema object- Oracle database object. Reference Key is the primary key that is referenced in the other table linked via the other tables Foreign Key. Tell me about DSN? Clustered Index Only one per table Faster to read than non clustered as data is physically stored in index order Non Clustered Index Can be used many times per table Quicker for insert and update operations than a clustered index.

NET 3. The term EXE is a shortened version of the word executable as it identifies the file as a program. On the other hand, DLL stands for Dynamic Link Library, which commonly contains functions and procedures that can be used by other programs.

Scenarios in which web application should be used and desktop application should be used? Tell how to check whether a linked list is circular. Create two pointers, each set to the start of the list. How can u increase the heap size in the memory?

If heap size set too low then you will get "out of memory" errors. If you set it too high then your system will hang or you will suffer poor performance because parts of the jvm will be swapped in and out of memory.

On Windows XP machines you can determine your free physical memory from the Performance tab of the Task Manager application. Boosting the heap size parameter will allow you to read in larger file-based projects. It will also improve the performance of the database back-end since more memory is available for caching. The Java heap occupancy often varies over time as the load applied to the application varies. Why is it difficult to store linked list in an array?

Both Arrays and Linked List can be used to store linear data of similar types. Linked list provide dynamic size while the size of array is fixed, So we must know the upper limit on the number of elements in advance. Linked lists have following drawbacks: 1 Random access is not allowed. We have to access elements sequentially starting from the first node. So we cannot do binary search with linked lists. Different types of keys in SQL? The different types of Keys in sql server are,.

A candidate key acts as a unique key. A unique key can be a Primary key. A candidate key can be a single column or combination of columns. Multiple candidate keys are allowed in a table. Primary Key. To uniquely identify a row, Primary key is used.

A table allows only one Primary key A Primary key can be a single column or combination of columns. Foreign Key. A primary key can be referred by multiple foreign keys from other tables. It is not required for a primary key to be the reference of any foreign keys. The interesting part is that a foreign key can refer back to the same table but to a different column.

Explain about Joins, Views, Normalization, Triggers? The JOIN keyword is used in an SQL statement to query data from two or more tables, based on a relationship between certain columns in these tables.

Tables in a database are often related to each other with keys. A view is a virtual table. A view contains rows and columns, just like a real table. The fields in a view are fields from one or more real tables in the database. Normalization is the process of efficiently organizing data in a database. There are two goals of the normalization process: eliminating redundant data for example, storing the same data in more than one table and ensuring data dependencies make sense only storing related data in a table.

Both of these are worthy goals as they reduce the amount of space a database consumes and ensure that data is logically stored. First Normal Form 1NF. Create separate tables for each group of related data and identify each row with a unique column or set of columns the primary key. Second Normal Form 2NF. Remove subsets of data that apply to multiple rows of a table and place them in separate tables. Create relationships between these new tables and their predecessors through the use of foreign keys.

Third Normal Form 3NF. Meet all the requirements of the second normal form. Remove columns that are not dependent upon the primary key. It also referred to as the "third and half 3. Every determinant must be a candidate key. Fourth Normal Form 4NF. Meet all the requirements of the third normal form. A relation is in 4NF if it has no multi-valued dependencies.

Remember, these normalization guidelines are cumulative. For a database to be in 2NF, it must first fulfill all the criteria of a 1NF database. Since triggers are event-driven specialized procedures, they are stored in and managed by the DBMS. A trigger cannot be called or executed; the DBMS automatically fires the trigger as a result of a data modification to the associated table.

Triggers are used to maintain the referential integrity of data by changing the data in a systematic fashion. Each trigger is attached to a single, specified table in the database. What is a default gateway? In organizational systems a gateway is a node that routes the traffic from a workstation to another network segment.

The default gateway commonly connects the internal networks and the outside network Internet. In such a situation, the gateway node could also act as a proxy server and a firewall. The gateway is also associated with both a router, which uses headers and forwarding tables to determine where packets are sent, and a switch, which provides the actual path for the packet in and out of the gateway. Given an array of 1s and 0s arrange the 1s together and 0s together in a single scan of the array.

Optimize the boundary conditions. Define Data Abstraction. What is its importance? Abstraction is the basis for software development. Its through abstraction we define the essential aspects of a system. The process of identifying the abstractions for a given system is called as Modeling or object modeling.

Three levels of data abstraction are: 1.
