The Most Important Data Warehouse Trends

1.Cloud Computing:- is a technology that enables users to access and use computing resources (like servers, storage, databases, networking, software, and more) over the internet on a pay-as-you-go basis. Rather than owning and maintaining physical hardware or infrastructure, cloud computing allows individuals and businesses to utilize these resources on-demand from a cloud service provider. It offers scalability, flexibility, cost-efficiency, and the ability to access data and applications from anywhere with an internet connection. The emergence of cloud computing has made a tremendous impact on the Information Technology (IT) industry over the past few years, where large companies such as Google, Amazon and cost-efficient cloud platforms, and business enterprises  seek to reshape their business models to gain benefit from this new paradigm[2]. In  cloud computing, 3 models are used such as Software as a Service (SaaS) is a model where software applications are hosted and provided by a third-party vendor over the internet With IaaS, users can access and manage fundamental computing resources such as virtual machines, storage, networking, and other infrastructure components without having to invest in or maintain physical hardware and PaaS typically offers a complete environment for developing, testing, deploying, and managing applications, including tools and services for coding, version control, database management, and  more.

Some Emerging Trends for 2024 in Cloud Computing:-The first under the Cloud Computing trends is the introduction of the Citizen developer. Google is also heavily invested in machine learning and its significance to their AI roadmap. This also includes for Better AI/ML and also the secret sauce for cloud is the potential for automation. Cloud providers are developing disaster recovery solutions that enable businesses to quickly recover from disruptions such as natural disasters or cyberattacks.Blockchain is a distributed ledger technology that is being integrated with cloud computing to create new applications and services.The Internet of Things (IoT) is a rapidly growing market in which cloud providers are investing. It develops solutions to help businesses manage and process a plethora of data generated by IoT devices.

2. Hybrid data warehousing:- In the hybrid warehouse the conceptual design relies on the graph-based multidimensional model for representing the integrated global schema andBloom filters are almost always beneficial when communicating data in the hybrid warehouse that integrates two massively parallel and heterogeneous data platforms, Broadcast joins can only be used in limited cases, because the data involved is usually very large. Data warehouses store vast amount of historical information ranging from very distant to very current transactions. For this purpose, data in the warehouse is frequently  combined or condensed making it uncomplicated to scan and query and access[3]. A study carried out by other research on the data warehouse system reviewed below. Okerenke, (2015): provide a hybrid framework for security issues in Data warehouse (which comprises the use of Username/Password and Token generation). The bottleneck in this work was that the system can only use password-based verification where Usernames are often a mixture of the individual’s first name and last name, this makes them guessable[4].

3. Real-time data processing:- A Real Time Data Warehouse (RTDW) can be termed as a system that represents the features and the actual situation of the organization. Two techniques are used to achieve real-time data warehousing one is using the Change Data Capture (CDC) technique and the integration of change data capture with existing ETL processes to maximize the performance of ETL and achieve real time ETL. In the contrary, migrating the data into data warehouse using conventional ETL tools has a latency problem with the large volumes of data sets because ETL processes consume substantial CPU resources and time for large data sets.

4. Self-service analytics:-Self-service BI is defined as business users being able to generate the reports they need throughout their daily work cycle without seeking the help of their IT department , As per Gartner. The need for Self-service data analytics is inevitable as it supports the business in making the right decisions.

5.Artificial intelligence and machine learning integration:-In data warehousing, integrating AI and ML involves leveraging these technologies to enhance data analysis, predictive modeling, and decision-making within the warehouse. This integration can optimize processes like data cleaning, pattern recognition, and predictive analytics, enabling better insights and informed business decisions. AI and ML algorithms can be applied to improve data quality, automate ETL processes, and extract valuable insights from vast amounts of data stored in the warehouse.

6. Data virtualization:- Data visualization plays a significant role in data warehousing by presenting complex data in a visually comprehensible manner. It allows users to grasp insights, patterns, and trends within the data more easily through charts, graphs, dashboards, and other visual representations. Tools like Tableau, Power BI, or Qlik are commonly used for effective data visualization in data warehousing systems.

7. Metadata management:- Metadata management in data warehousing involves the organization, storage, and management of metadata—information about the data stored in the data warehouse. It includes details such as data source, structure, relationships, definitions, and usage. Effective metadata management ensures data quality, improves understanding of the data, assists in data governance, and helps in facilitating data integration and analysis within the data warehouse environment.Metadata is essential for the successful operation of data files, as it acts as the underlying data that helps maintain and manage the namespace, permissions, and address of the file data blocks[5]. Metadata access in the distributed file system can be increased by Caching and prefetching operations[6]. Metadata is available for re-use by other applications, and has a built change management system facilitating a check-in/check-out system with history and audit trails.

8. Data lakes and data warehouses convergence:-The convergence of data lakes and data warehouses involves blending their capabilities to create a unified and flexible data management infrastructure. It combines the scalability and agility of data lakes, which store raw and unstructured data, with the structured, optimized querying of data warehouses. This convergence aims to improve accessibility, reduce data silos, and enhance analytics by allowing organizations to efficiently store, process, and analyze diverse data types in one place.

The primary mission of the IDW is to link the knowledge warehouse and the data warehouse processes with operational system to bring quality, functionality and information sharing. The IDW knowledge warehouse like the DW contains information about the business, this information helps to control the process, reporting from both OLTP and DW data. The DW will contain data in support of knowledge warehouse specific business goals by presenting data from a historical data, data validation.

DW/DA Withfirst generation business intelligence

The integration of data warehousing and data analysis with first-generation business intelligence marked a significant milestone in enhancing organizational decision-making.BI software and organizational strategy into BI Remedies, and to ensure the on-going achievement of the objectives associated with the BI process[10]. BI software products, on the other hand, are assets which are readily available in factor markets.[11].  Similarly, BI software implementation services can be purchased and the on-going maintenance of BI solutions can also be outsourced. Early BI tools leveraged structured data from data warehouses, providing a foundation for reporting and basic analysis. However, limitations such as rigid reporting structures and slower data processing hindered real-time insights. Despite these constraints, the combination of data warehousing and first-generation BI laid the groundwork for understanding historical trends and making informed decisions. This symbiotic relationship paved the way for subsequent generations of BI to address shortcomings, ultimately evolving into more dynamic, real-time, and user-friendly solutions. Acknowledging the historical context is crucial for appreciating the continuous advancements in the field of business intelligence.
