51. Tables are Not Your Friends: Graph Databases

Author

Guy Harrison

Subjects
Social graph, Information retrieval, Graph database, Computer science, Relational database, Binary number, computer.file_format, computer.software_genre, JSON, Database design, RDF, computer, ComputingMilieux_MISCELLANEOUS, computer.programming_language
Abstract

Proponents of key-value stores, document databases, and relational systems disagree about practically every aspect of database design, but they do agree in one respect: databases are about storing information about “things,” be those things represented by JSON, tables, or binary values. But sometimes it’s the relationship between things, rather than the things themselves, that are of primary interest. This is where graph database systems shine.

Abstract

The last time we saw a major new brand of relational database was around 1995, with the first release of MySQL. In 1995, the World Wide Web in the United States was barely two years old—the Netscape browser had been released only the year before. In terms of computer systems, it was a different era.

56. Data Models and Storage

Author

Guy Harrison

Subjects
Flexibility (engineering), Data access, Computer science, Star schema, Redundancy (engineering), Relational model, Data science, NewSQL, Data modeling, Variety (cybernetics)
Abstract

The relational database model provided a strong theoretical foundation for the representation of data that eliminated redundancy and maximized flexibility of data access. Many next-generation database systems, particularly those of the NewSQL variety, continue to embrace the relational model: their innovations generally focus on the underlying physical storage of data.

Abstract

In the history of computing, nothing has raised the profile of data processing, storage, and analytics as much as the concept of Big Data. We have considered ourselves to be an information-age society since the 1980s, but the concentration of media and popular attention to the role of data in our society have never been greater than in the past few years–thanks to Big Data.

59. Three Database Revolutions

Author

Guy Harrison

Subjects
ComputingMilieux_GENERAL, Scope (project management), Database, Computer science, Relational database, business.industry, Relational model, Cloud computing, Electronic computer, business, computer.software_genre, computer
Abstract

This book is about a third revolution in database technology. The first revolution was driven by the emergence of the electronic computer, and the second revolution by the emergence of the relational database. The third revolution has resulted in an explosion of nonrelational database alternatives driven by the demands of modern applications that require global scope and continuous availability. In this chapter we’ll provide an overview of these three waves of database technologies and discuss the market and technology forces leading to today’s next generation databases.

60. Distributed Database Patterns

Abstract

Administrators of web applications have traditionally had two choices when the application demand exceeds database capacity: scaling up by increasing the power of individual servers, or scaling out by adding more servers. For most of the relational database era, scaling up was the more practical option. Early relational databases did not provide a clustering option, whereas the CPU and memory supplied by a single server was constantly and exponentially increasing in line with Moore’s law. Consequently, scaling out was neither practical nor necessary.

Abstract

This book is the story of how a revolution in database technology saw the “one size fits all” traditional relational SQL database give way to a multitude of special-purpose database technologies. In the past 11 chapters, we have reviewed the major categories of next-generation database systems and have taken a deep dive into some of the internal architectures of those systems.

Abstract

Crucial to the dominance of the relational database was the almost universal adoption of the SQL language as the mechanism for querying and modifying data. SQL is not a perfect language, but it has demonstrated sufficient flexibility to meet the needs of both non-programming database users and professional database programmers. Programmers embed SQL in programming languages, while non-programmers use SQL either explicitly within a query tool or implicitly when a BI tool uses SQL under the hood to talk to the database. Prior to the introduction of SQL, most IT departments labored with a backlog of requests for reports; SQL allowed the business user to “self-serve” these requests.

Subjects
Orders of magnitude (bit rate), Hardware_MEMORYSTRUCTURES, Database, Computer science, computer.software_genre, computer
Abstract

Ever since the birth of the first database systems, database professionals have strived to avoid disk IO at all costs. IO to magnetic disk devices has always been many orders of magnitude slower than memory or CPU access, and the situation has only grown worse as Moore’s law accelerated the performance of CPU and memory while leaving mechanical disk performance behind.

Abstract

Oracle Performance Survival Guide A Systematic Approach to Database Optimization The fast, complete, start-to-finish guide to optimizing Oracle performance Oracle Performance Survival Guide offers a structured, systematic, start-to-finish methodology for optimizing Oracle performance as efficiently as possible. Leading Oracle expert Guy Harrison shows how to maximize your tuning investment by focusing on causes rather than symptoms, and by quickly identifying the areas that deliver the greatest “bang for the buck.” Writing for DBAs and developers with all levels of experience, Harrison covers every area of Oracle performance management, from application design through SQL tuning, contention management through memory and physical IO management. He also presents up-to-the-minute guidance for optimizing the performance of the Oracle 11g Release 2. You'll start by mastering Oracle structured performance tuning principles and tools, including techniques for tracing and monitoring Oracle execution. Harrison illuminates the interaction between applications and databases, guides you through choosing tuning tools, and introduces upfront design techniques that lead to higher-performance applications. He also presents a collection of downloadable scripts for reporting on all aspects of database performance. Coverage includes • “Tuning by layers,” the most effective, highest-value approach to Oracle performance optimization • Making the most of Oracle's core tools for tracing, monitoring, and diagnosing performance • Highly efficient database logical and physical design, indexing, transaction design, and API use • SQL and PL/SQL tuning, including the use of parallel SQL techniques • Minimizing contention for locks, latches, shared memory, and other database resources • Optimizing memory and physical disk IO • Tuning Real Application Cluster (RAC) databases guyharrison.net informit.com/ph
