Introduction In context of distributed systems, exception handling refers to process of detecting, diagnosing, and recovering from errors that occur in a distributed system. In such systems, errors can occur at any point in communication and coordination process, including network failures, hardware malfunctions, and software bugs. Thus, effective exception handling is crucial to ensure reliability and availability of a distributed system. In this article, we will explore various techniques and best practices for exception handling in distributed systems. Importance of Exception Handling in Distributed Systems In a distributed system, multiple processes run on different machines and communicate with each other ... Read More

Introduction Distributed computing systems refer to a network of interconnected devices that share resources and work together to achieve a common goal. evolution of distributed computing systems has been rapid, and it has transformed way we use technology in our daily lives. From simple file sharing systems to advanced cloud computing, distributed computing systems have come a long way. In this article, we will discuss evolution of distributed computing systems and explore some of examples. Early Days of Distributed Computing The early days of distributed computing can be traced back to 1960s, where researchers began experimenting with idea of sharing ... Read More

Introduction Distributed systems have become an integral part of our modern-day technological infrastructure. They have made it possible to deliver services at scale, provide better resilience, and enable better fault tolerance. However, designing distributed systems is a challenging task, and one of most significant challenges is maintaining ordering of events in system. This article will discuss event ordering in distributed systems and provide examples of different techniques used to achieve it. Event Ordering Event ordering is essential in distributed systems because it determines order in which events occur. In a distributed system, events can happen concurrently on different nodes, and ... Read More

Open Database Connectivity (ODBC) is a common API (Application Programming Interface) that enables programmes to connect to different database management systems (DBMS) using a standardised interface. Regardless of how a database's native interface is configured, the ODBC interface offers a consistent mechanism for programmes to communicate with it. The connectivity of ODBC, including its design, drivers, and connections, will be examined in more detail in this article. ODBC Architecture Flow Diagram of ODBC Architecture The three primary parts of the ODBC architecture are the application, the ODBC Driver Manager, and the ODBC driver. Each piece of software that needs ... Read More

Cassandra is a NoSQL database that is made to manage massive volumes of data over several nodes and is extremely scalable. Data distribution over numerous nodes in a cluster, which enables high availability and fault tolerance, is one of Cassandra's core characteristics. In this post, we'll go through the syntax and examples for configuring Cassandra clusters. Configuring a Cassandra Cluster Let's first talk about the fundamental structure of a Cassandra cluster before getting into the specifics of constructing one. Many nodes, each of which can either be a seed node or a normal node, make up a Cassandra cluster. The ... Read More

In conclusion, creating a Cassandra cluster entails selecting the seed nodes, setting the replication factor, configuring the IP addresses and ports for each cluster node, as well as additional configuration options like the cluster name. The main configuration file for Cassandra clusters is the cassandra.yaml file. Cassandra clusters may offer high availability and fault tolerance for massive volumes of data with the proper configuration. You may effectively configure a Cassandra cluster to suit your unique requirements by adhering to the syntax and examples shown in this article. Syntax UPDATE table_name SET column1 = value1, column2 = value2, ... WHERE condition; ... Read More

View-equivalence is a term used in database management systems to describe the circumstance in which two schedules, when applied to the same database, yield the same result set. This requirement is necessary to guarantee data correctness and consistency in database applications. There are requirements that schedules must meet in order to achieve view equality. These circumstances are − Conflict Serializability − The conflicting operations in a schedule must be performed in the same sequence for it to be conflict serializable. Operations that access the same data item and at least one of which affects the data are said to ... Read More

Several transactions can be carried out simultaneously in a shared database when using a database management system (DBMS).Concurrent execution can provide a number of benefits, including increased system capacity and quicker reaction times. To ensure accurate and dependable database functioning, there may be a number of issues that need to be resolved. We shall talk about concurrent execution in DBMSs and its issues in this post. Concurrent execution in a DBMS refers to the capacity to carry out numerous transactions simultaneously in a shared database. A collection of database activities known as a transaction, such as inserting, updating, or removing ... Read More
