Download or read book Database Architecture Design Memory to Storage using DB2 written by Lawrence Dunn and published by Dominion Publishing. This book was released on 2016-04-14 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: It continues to amaze me on the number of corporations running data-based applications on DB2 who view it as a black-box that simply houses their application data. This disconnect with the importance of properly designed and more importantly…configured…data bases leads to application error, lowered customer satisfaction, drastically decreased potential being proactive with KPI’s and increased hardware and support costs. This disconnect is so prevalent, that many organizations assume that the solution to a badly performing database is adding a score of new indexes, buying more memory or worse going through a massive conversion/upgrade effort with a new product. Capital expenditure on additional memory and storage for a database that simply needs to be properly configured for its’ workload is something that I see various companies do every year and it’s a massive waste of shareholder equity. In a previous life, I was responsible for capacity planning with Procter & Gamble’s technical infrastructure. Following the Pareto Principle (i.e., 80 /20 rule), the first thing that I did was identify which portion of the infrastructure was responsible for the highest costs in support, licensing and new expenditures. Three IBM 3090 mainframes jumped out with the highest costs so I initially placed my focus there. Looking at daily workloads of each environment what became apparent was that the utilization between each machine ran a little over 40%. This was a massive waste of resources. So I simply rebalanced the workload, dividing processing between two machines and eliminating the third. This simple act of effectively spreading workload utilization saved P&G $2M/year. The workload within a DB2 database can also be effectively spread with an effective buffer pool and storage strategy. This will drastically improve overall performance, eliminating the need to acquire additional memory and lowering support costs. I’ve been in numerous pre-sales situations were a client will sign a contract to purchase a data based application and as the ink is drying they will then ask architecture questions that they should have addressed beforehand: · What type of DB2 license should we buy? · How much memory will we need? · How much storage? · What kind of storage? · How many LUNs will we need to configure? · How many CPU’s will we need? These are all very relevant questions that should be addressed…before…making the decision to purchase a shiny new data based application. However, in my experience the key after the fact question that is rarely asked is, “What type of performance should I expect?” In my experience performance is seldom discussed during project startup, but it is…always…brought up once the application is in production. The issue as I stated earlier, is that many technical professionals view DB2 as a black-box in that they are only concerned with…space. With this fixated view they look at the potential size of the database to figure out how much storage to purchase. Then the storage size is used to guestimate the amount of memory and CPU that should be required. The assumption is made that adequately estimating hardware based on database size will also equate into having adequate performance. This is a woefully inadequate assumption that will lead to subpar performance in your production environment. This white paper will illustrate via a case study the benefits of completing a database architecture design as one of the first project deliverables that contains the database configuration parameters, bufferpool design, tablespace design, LUN design, and device/file design. This will ensure optimal database performance and low capital expenditures for your project.

Download or read book Database Design and Implementation written by Edward Sciore and published by Springer Nature. This book was released on 2020-02-27 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook examines database systems from the viewpoint of a software developer. This perspective makes it possible to investigate why database systems are the way they are. It is of course important to be able to write queries, but it is equally important to know how they are processed. We e.g. don’t want to just use JDBC; we also want to know why the API contains the classes and methods that it does. We need a sense of how hard is it to write a disk cache or logging facility. And what exactly is a database driver, anyway? The first two chapters provide a brief overview of database systems and their use. Chapter 1 discusses the purpose and features of a database system and introduces the Derby and SimpleDB systems. Chapter 2 explains how to write a database application using Java. It presents the basics of JDBC, which is the fundamental API for Java programs that interact with a database. In turn, Chapters 3-11 examine the internals of a typical database engine. Each chapter covers a different database component, starting with the lowest level of abstraction (the disk and file manager) and ending with the highest (the JDBC client interface); further, the respective chapter explains the main issues concerning the component, and considers possible design decisions. As a result, the reader can see exactly what services each component provides and how it interacts with the other components in the system. By the end of this part, s/he will have witnessed the gradual development of a simple but completely functional system. The remaining four chapters then focus on efficient query processing, and focus on the sophisticated techniques and algorithms that can replace the simple design choices described earlier. Topics include indexing, sorting, intelligent buffer usage, and query optimization. This text is intended for upper-level undergraduate or beginning graduate courses in Computer Science. It assumes that the reader is comfortable with basic Java programming; advanced Java concepts (such as RMI and JDBC) are fully explained in the text. The respective chapters are complemented by “end-of-chapter readings” that discuss interesting ideas and research directions that went unmentioned in the text, and provide references to relevant web pages, research articles, reference manuals, and books. Conceptual and programming exercises are also included at the end of each chapter. Students can apply their conceptual knowledge by examining the SimpleDB (a simple but fully functional database system created by the author and provided online) code and modifying it.

The first complete treatment on physical database design, written by the authors of the seminal, Database Modeling and Design: Logical Design, Fourth Edition Includes an introduction to the major concepts of physical database design as well as detailed examples, using methodologies and tools most popular for relational databases today: Oracle, DB2 (IBM), and SQL Server (Microsoft) Focuses on physical database design for exploiting B+tree indexing, clustered indexes, multidimensional clustering (MDC), range partitioning, shared nothing partitioning, shared disk data placement, materialized views, bitmap indexes, automated design tools, and more!

Download or read book Building a Columnar Database on RAMCloud written by Christian Tinnefeld and published by Springer. This book was released on 2015-07-07 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the field of parallel database management systems and illustrates the great variety of solutions based on a shared-storage or a shared-nothing architecture. Constantly dropping memory prices and the desire to operate with low-latency responses on large sets of data paved the way for main memory-based parallel database management systems. However, this area is currently dominated by the shared-nothing approach in order to preserve the in-memory performance advantage by processing data locally on each server. The main argument this book makes is that such an unilateral development will cease due to the combination of the following three trends: a) Today’s network technology features remote direct memory access (RDMA) and narrows the performance gap between accessing main memory on a server and of a remote server to and even below a single order of magnitude. b) Modern storage systems scale gracefully, are elastic and provide high-availability. c) A modern storage system such as Stanford’s RAM Cloud even keeps all data resident in the main memory. Exploiting these characteristics in the context of a main memory-based parallel database management system is desirable. The book demonstrates that the advent of RDMA-enabled network technology makes the creation of a parallel main memory DBMS based on a shared-storage approach feasible.
