Introduction Optimizing IT Across Cloud and On-Premises Environments Public sector organizations continue to do more with less, find ways to innovate and bring new ideas to their organizations while dealing with security and maintaining mission-critical legacy systems. Evolving cloud capabilities are transforming the IT landscape for many public sector organizations, some use cases a hybrid cloud approach can help ease and accelerate a path to modernization and cloud adoption. For some use cases a hybrid cloud approach became a more feasible path to IT modernization and cloud adoption. For example, some customers have applications that require the lowest network latency possible, or they already achieve consistent and predicable performance in an on- premises environment, but want to use new cloud tools to enhance the application (e.g. Enterprise Resource Planning systems, real-time sensor data processing, industrial automation and transaction processing). Some customers may encounter unique challenges such as federal regulations associated with data residency, or limitations on their use of the cloud. A hybrid cloud (the use of both on-premises and cloud resources), allows IT organizations to optimize the performance and costs of every application, project and system in either the cloud, on-premises datacenters, or a combination of both. -
Magic Quadrant for Enterprise High-Productivity Application Platform As a Service
This research note is restricted to the personal use of [email protected]. Magic Quadrant for Enterprise High- Productivity Application Platform as a Service Published: 26 April 2018 ID: G00331975 Analyst(s): Paul Vincent, Van Baker, Yefim Natis, Kimihiko Iijima, Mark Driver, Rob Dunie, Jason Wong, Aashish Gupta High-productivity application platform as a service continues to increase its footprint across enterprise IT as businesses juggle the demand for applications, digital business requirements and skill set challenges. We examine these market forces and the leading enterprise vendors for such platforms. Market Definition/Description Platform as a service (PaaS) is application infrastructure functionality enriched with cloud characteristics and offered as a service. Application platform as a service (aPaaS) is a PaaS offering that supports application development, deployment and execution in the cloud. It encapsulates resources such as infrastructure. High- productivity aPaaS (hpaPaaS) provides rapid application development (RAD) features for development, deployment and execution — in the cloud. High-productivity application platform as a service (hpaPaaS) solutions provide services for declarative, model-driven application design and development, and simplified one-button deployments. They typically create metadata and interpret that metadata at runtime; many allow optional procedural programming extensions. The underlying infrastructure of these solutions is opaque to the user as they do not deal with servers or containers directly. The rapid application development (RAD) features are often referred to as "low-code" and "no-code" support. These hpaPaaS solutions contrast with those for "high-control" aPaaS, which need professional programming — "pro-code" support, through third-generation languages (3GLs) — and provide transparent access to the underlying infrastructure. -
Blockchain Database for a Cyber Security Learning System
Session ETD 475 Blockchain Database for a Cyber Security Learning System Sophia Armstrong Department of Computer Science, College of Engineering and Technology East Carolina University Te-Shun Chou Department of Technology Systems, College of Engineering and Technology East Carolina University John Jones College of Engineering and Technology East Carolina University Abstract Our cyber security learning system involves an interactive environment for students to practice executing different attack and defense techniques relating to cyber security concepts. We intend to use a blockchain database to secure data from this learning system. The data being secured are students’ scores accumulated by successful attacks or defends from the other students’ implementations. As more professionals are departing from traditional relational databases, the enthusiasm around distributed ledger databases is growing, specifically blockchain. With many available platforms applying blockchain structures, it is important to understand how this emerging technology is being used, with the goal of utilizing this technology for our learning system. In order to successfully secure the data and ensure it is tamper resistant, an investigation of blockchain technology use cases must be conducted. In addition, this paper defined the primary characteristics of the emerging distributed ledgers or blockchain technology, to ensure we effectively harness this technology to secure our data. Moreover, we explored using a blockchain database for our data. 1. Introduction New buzz words are constantly surfacing in the ever evolving field of computer science, so it is critical to distinguish the difference between temporary fads and new evolutionary technology. Blockchain is one of the newest and most developmental technologies currently drawing interest. -
Price-Performance in Modern Cloud Database Management Systems
Price-Performance in Modern Cloud Database Management Systems McKnight Consulting Group December 2019 www.m c k n i g h t c g . c o m Executive Summary The pace of relational analytical databases deploying in the cloud are at an all-time high. And industry trends indicate that they are poised to expand dramatically in the next few years. The cloud is a disruptive technology, offering elastic scalability vis-à-vis on-premises deployments, enabling faster server deployment and application development, and allowing less costly storage. The cloud enables enterprises to differentiate and innovate with these database systems at a much more rapid pace than was ever possible before. For these reasons and others, many companies have leveraged the cloud to maintain or gain momentum as a company. The cost profile options for these cloud databases are straightforward if you accept the defaults for simple workload or POC environments. However, it can be enormously expensive and confusing if you seek the best price-performance for more robust, enterprise workloads and configurations. Initial entry costs and inadequately scoped POC environments can artificially lower the true costs of jumping into a cloud data warehouse environment. Cost predictability and certainty only happens when the entire picture of a production data warehouse environment is considered; all workloads, a true concurrency profile, an accurate assessment of users and a consideration of the durations of process execution. Architects and data warehouse owners must do their homework to make the right decision. With data warehouses, it is a matter of understanding the ways they scale, handle performance issues and concurrency. -

The naïve observer may conclude that such variety of database replication from both academia and industry. However, replication systems indicates a solved problem; the reality, academic groups often attack replication problems in isolation, however, is the exact opposite. Replication still falls short of overlooking the need for completeness in their solutions, while customer expectations, which explains the continued interest in developing new approaches, resulting in a dazzling variety of commercial teams take a holistic approach that often misses offerings. opportunities for fundamental innovation. This has created over time a gap between academic research and industrial practice. Even the “simple” cases are challenging at large scale.

What Is a Database? Differences Between the Internet and Library
What is a Database? Library databases are mostly full-text material (in their entirety) and summaries or descriptions of articles. They are collections of articles from newspapers, magazines and journals and electronic reference sources. Databases are selected for the quality and variety of resources they offer and are accessed using the Internet. Your library pays for you to have access to a number of relevant databases. You support this with your tuition, so get the most out of your money! You can access them from home or school via the Library Webpage or use the link below. http://www.mxcc.commnet.edu/Content/Find_Articles.asp Two short videos on the benefits of using library databases: http://www.youtube.com/watch?v=VUp1P-ubOIc http://youtu.be/Q2GMtIuaNzU Differences Between the Internet and Library Databases The Internet Library Databases Examples Google, Yahoo, Bing LexisNexis, Literary Reference Center or Health and Wellness Resource Center Review process None – anyone can add Checked for accuracy by content to the Web. publishers.

Run Critical Databases in the Cloud
Cloud Essentials Run Critical Databases in the Cloud Oracle has the most complete data management portfolio for any enterprise workload. Cloud computing is transforming business practices and simplifying data center operations. However, when it comes to moving critical database assets to the cloud, many IT leaders are cautious—and rightly so. They have seen the limitations of popular commodity cloud solutions, which mostly consist of fragmented hardware and software offerings that must be manually configured. IT pros must build their own platforms on top of the service provider’s commodity infrastructure, migrate their data, and then figure out how to keep everything in sync with the apps and data still maintained on premise. Oracle Autonomous Database provides enterprise-level scalability, security, performance, and automation—at a level that often exceeds what you can achieve in your own data center. You can subscribe to complete database platforms with a few clicks, eliminating the need to provision, build, and manage in-house databases and storage systems. With pay-as-you-grow configurations—all managed by Oracle experts— your organization will obtain operational flexibility with zero up-front capital expenses. It’s a great way to lower operational costs because you pay only for what you use. Read on to discover what a powerful cloud database can do for your business. Migrating to a Cloud Computing Model Modern businesses depend on their data more than cloud services work together automatically— ever before. That data is coming at an alarming rate, and in many cases, autonomously. placing crushing demands on data marts, enterprise data warehouses, and analytics systems. -

To Appear in the Ninth International Conference on Data Engineering Vienna, Austria April 1993 Data Quality Requirements Analysis and Modeling Richard Y. Wang Henry B. Kon Stuart E. Madnick Sloan School of Management Massachusetts Institute of Technology Cambridge, Mass 02139 [email protected] ABSTRACT Data engineering is the modeling and structuring of data in its design, development and use. An ultimate goal of data engineering is to put quality data in the hands of users. Specifying and ensuring the quality of data, however, is an area in data engineering that has received little attention. In this paper we: (1) establish a set of premises, terms, and definitions for data quality management, and (2) develop a step-by-step methodology for defining and documenting data quality parameters important to users. These quality parameters are used to determine quality indicators, to be tagged to data items, about the data manufacturing process such as data source, creation time, and collection method.
