Research Paper A research paper is an academic writing in which students have to collect information related to a given topic. They have to make an organized report regarding the subject which can include the research they have conducted or the research already done by other students. ... Read More
David Korn developed the Korn Shell command which is used by developers to create new shell commands. Freeware Software developed Bash Shell which is a free and open-source script and can be used by computer users. In this article, we will discuss the difference between the Korn shell and the Bash shell. Korn Shell Korn shell is a command for Unix operating system and David Korn has developed it under Bell Labs. A shell program is a command which runs different types of scripts by interfacing with the operating system. Korn shell is a script that can run on different ... Read More
Sorting refers to arranging data in a particular format. Sorting algorithm specifies the way to arrange data in a particular order (ascending or descending). Problem Statement For a given array write Java program to sort integers in unsorted array. Consider the following example - Input The unsorted integer array = [10, 14, 28, 11, 7, 16, 30, 50, 25, 18] Output The unsorted integer array = [10, 14, 28, 11, 7, 16, 30, 50, 25, 18] The sorted integer array = [7, 10, 11, 14, 16, 18, 25, 28, 30, 50] Sorting Integers in Unsorted Array ...

Introduction Have you been grappled with slow database performance and clueless how to optimize it? Fact is, efficient physical database design and tuning can significantly enhance your database operations. In this enlightening article, we will unravel practical methods that revamp your system's speed by addressing bottlenecks, utilizing proper indexing strategies, optimizing queries, storage management and much more. Overview of Physical Database Design Physical database design plays a crucial role in the overall performance and efficiency of a database system, as it involves making decisions about how the data is stored, organized, and accessed at the physical level. Importance Physical ... Read More
Introduction To ensure both concurrency control and data integrity within database management systems (DBMS). Several locking mechanisms are employed — among them, one is being predicate locking. By utilizing this particular type of lock for protecting specified sections of the stored information from conflicting operations seeking simultaneous access. DBMS guarantees foolproof security measures. By designating a single transaction at a time for reading or modifying a given set of records predicate locking effectively eliminates inconsistencies that might occur due to concurrent access. Moreover. The lock is directly associated with specific predicates. Making it feasible for different subsets of ... Read More
Introduction Primary indexing is a crucial component of database management systems as it greatly enhances the efficiency of retrieving data. Its main objective is to establish a primary key and index. Which in turn enables quick and precise searches. By assigning a unique identifier to each record and creating an index. Primary indexing permits rapid access to specific data. Not only does it improve the overall performance of the system but it also facilitates efficient operations such as record insertion and updates while minimizing disk input/output operations. In this era of digital advancements primary indexing is an essential ... Read More
An algorithm is defined as a finite set of instructions that, if followed, performs a particular task. All algorithms must satisfy the following criteria - Input An algorithm has zero or more inputs, taken or collected from a specified set of objects. Output An algorithm has one or more outputs having a specific relation to the inputs. Definiteness Each step must be clearly defined; Each instruction must be clear and unambiguous. Finiteness The algorithm must always finish or terminate after a finite number of steps. Effectiveness All operations to be accomplished must be sufficiently basic that they can be ... Read More
