The document discusses temporal databases and time-varying data. It provides definitions and examples of temporal databases, time-varying data, and the two dimensions of time - valid and transaction time. It also summarizes different approaches to implementing temporal databases and reasons for their increasing relevance.
The document discusses and compares MapReduce and relational database management systems (RDBMS) for large-scale data processing. It describes several hybrid approaches that attempt to combine the scalability of MapReduce with the query optimization and efficiency of parallel RDBMS. HadoopDB is highlighted as a system that uses Hadoop for communication and data distribution across nodes running PostgreSQL for query execution. Performance evaluations show hybrid systems can outperform pure MapReduce but may still lag specialized parallel databases.
The document provides an overview of Query-by-Example (QBE) and Datalog, two relational query languages. QBE allows graphical queries to be expressed "by example" using relation templates. It supports queries on single and multiple relations, negation, conditions, ordering results, and aggregate functions. Datalog is a logic-based query language based on rules that define views. It allows recursion and negation. Key features include safety and the power of recursive queries.
This document summarizes an introduction to advanced MySQL query and schema tuning techniques presented by Alexander Rubin. It discusses how to identify and address slow queries through better indexing, temporary tables, and query optimization. Specific techniques covered include using indexes to optimize equality and range queries, ordering fields in composite indexes, and avoiding disk-based temporary tables for GROUP BY and other complex queries.
This document discusses temporal databases. It begins with an introduction that defines a temporal database as one that contains time-varying data and understands the passage of time. It then provides background on the history of temporal databases, including how they were developed to address limitations in early databases. The focus and discussion sections explain key aspects of temporal databases, including their features, implementations, and forms (valid time and transaction time). The conclusion reiterates that temporal databases express changing data over real time and make updating and querying time-related information easier.
Performance tuning and optimization (ppt)Harish Chand
The document discusses various ways to improve client/server performance at both the client and server level. It addresses:
1) Client performance can be improved by optimizing hardware and software. Hardware optimizations include using the fastest available components, while software optimizations involve improving the operating system and applications.
2) Server performance can also be improved through hardware upgrades like adding network cards, as well as implementing high-performance file systems and offloading processing to servers.
3) Database performance optimizations involve efficient index design, query design, and database normalization to minimize network traffic and process data faster.
This document provides an overview of the object-oriented database model. It describes how the model was developed from the semantic data model in 1981. The key aspects of the object-oriented database model are that data and relationships are contained within objects, objects can inherit attributes and methods from parent classes, and classes are organized in a hierarchy. Unified Modeling Language class diagrams can be used to graphically represent the data relationships in an object-oriented system.
An Object Oriented DBMS stores data as objects that use object-oriented concepts like classes, inheritance, and encapsulation. Objects have attributes that can be simple like integers or complex like collections. Classes group similar objects and subclasses inherit attributes and behaviors from superclasses. Objects communicate through messages that invoke methods. The DBMS maps classes and objects to tables and tuples in a relational database, which loses some semantic information about class hierarchies.
The document discusses various disaster recovery strategies for SQL Server including failover clustering, database mirroring, and peer-to-peer transactional replication. It provides advantages and disadvantages of each approach. It also outlines the steps to configure replication for Always On Availability Groups which involves setting up publications and subscriptions, configuring the availability group, and redirecting the original publisher to the listener name.
The document provides an overview of key concepts in database foundation training including:
1) It discusses database objects like tables, views, stored procedures, functions, triggers, and indexes.
2) It describes different types of databases like relational, flat file, and different database management systems.
3) It explains database concepts such as transactions, data definition language commands, and the difference between online transaction processing and online analytical processing databases.

Windows azure sql_database_security_isug012013sqlserver.co.il
This document discusses security for Microsoft SQL Azure (now called Windows Azure SQL Database). It provides an overview of SQL Database and its security capabilities, best practices for securing SQL Database like using encryption and configuring firewall rules, and limitations compared to on-premises SQL Server. It also introduces GreenSQL as a software-based database proxy that can provide additional security functionality for SQL Database like preventing SQL injection, auditing, and data masking. GreenSQL aims to offer a more complete solution for security, compliance, and hybrid application support compared to the native capabilities in SQL Database.
The document discusses the SQL Server plan cache, which stores and reuses query execution plans. It describes what is stored in the plan cache, how plans are looked up and aged out, and dynamic management views for exploring the plan cache. Methods covered include identifying unoptimized ad hoc queries, parameterizing queries for better plan reuse, and handling cases where plan reuse is not possible like with local variables.
This document summarizes upcoming SQL Server events in January 2013 in Israel, including multi-day training sessions, user group meetings, and virtual chapter meetings on SQL Server administration and development topics. It also lists current job openings and previews the tips and presentations for an upcoming user group meeting, including how Database Administration Console improvements in SQL Server 2012 will impact administrators and real-world query tuning case studies.
The document discusses the evolution of data-tier applications (DACs) and database administration over time. It notes that in the past, database administrators (DBAs) and developers worked in silos, making development, deployment, and management challenging. Recent investments in tools like SQL Server Data-tier Applications (DACs) now allow for more integrated development workflows and easier deployment and management of databases at scale. The document outlines some key concepts and enhancements in DACs over multiple versions to improve collaboration and move developers to a more declarative model.
The document discusses the role of the SQL query optimizer in generating efficient query plans. It describes the optimizer's multi-stage process of parsing the SQL statement, binding objects, optimizing through different search levels, applying logical and physical properties and over 350 rules to simplify and optimize the query tree, and selecting the cheapest plan. It notes challenges like a large number of possible join orders and timeouts during complex optimizations.
The document describes several SQL server monitoring and management tools from Docco Labs, including ClipTable for data import, Database File Explorer for file usage monitoring, Log Table Viewer for logging, and SQL Stripes for server monitoring and control.

It aims to fill the gap between generic monitoring tools and agent-specific alerts.
Introducing 3 FREE Smart solutions for SQL Server (Adi Sapir, Docco Labs)
As Database experts, we work with SQL Server Databases on a daily basis. We face the same problems every SQL Administrator and/or developer does. And – we spend our time writing solutions for these problems! In this session Adi will introduce the following 3, totally FREE solutions:
· ClipTable – A revolutionary new *anything* to SQL Table importer
· Database File Explorer – a much easier way to explore our database->filegroups->files->storage mapping
· Log Table Viewer – a complete client/server logger solution for SQL Server
Read committed snapshot isolation (RCSI) allows readers to see committed data without blocking writers or other readers. It can greatly reduce locking and deadlocking. SQL Server supports partition-level lock escalation, allowing concurrent access to different partitions. Filtered indexes improve performance by indexing a subset of table data. Optimize for ad hoc workloads improves plan caching for queries that are run infrequently. Enabling data compression reduces database size and storage costs without requiring application changes.
- Distributed Replay allows replaying a captured workload from multiple client computers to better simulate production loads.
- A controller coordinates the replay across clients to reproduce the original query rates or run in stress test mode faster than original rates.
- It improves on SQL Server Profiler for application compatibility testing, performance debugging, capacity planning, and benchmarking.
- Events are replayed in synchronization mode to match original order, or unsynchronized to stress test without timing constraints.
Predicates allow filtering events based on:
- Event properties (fields)
- Session properties
- System properties
They are evaluated synchronously when the event fires. This allows filtering events and reducing overhead compared to capturing all events.
Common predicates:
- event_name = 'sql_statement_completed'
- database_id = 5
- cpu_time > 1000
Predicates give granular control over what events are captured.
The document discusses enhancements to Extended Events in SQL Server 2012. It provides an overview of Extended Events, terminology used in Extended Events, and highlights key enhancements in SQL Server 2012 such as an improved user interface, expanded system coverage, and a managed code API.
SQL Explore 2012 - Michael Zilberstein: ColumnStoresqlserver.co.il
This document discusses how columnstore indexes in Microsoft SQL Server can boost query performance. It provides an overview of column-oriented databases and columnstore technology. Columnstore indexes store data by column rather than by row, allowing for improved compression techniques like dictionary encoding. This reduces storage space and I/O. It also allows for more efficient query processing through batch execution and new execution plan elements. The document outlines best practices, limitations, issues and workarounds, as well as how to load data with columnstore indexes. It provides references for further reading on columnstore performance tuning.
- The document discusses the challenges of database development and deployment processes and how the Data-Tier Application Framework (DAC Fx) addresses these challenges.
- DAC Fx allows developers to model the database in a declarative way and generates deployment scripts and files (.dacpac) that simplify the deployment process for both developers and DBAs.
- It also enables cross-platform deployment of databases to both on-premises and cloud platforms like SQL Azure.
SQL Server 2012 introduced new spatial data types like circular arcs and support for full globe objects. It also enhanced spatial indexing with automatic grid generation and index hints. Other improvements included additional methods for spatial aggregations and reorienting objects on the globe. Overall, the new capabilities expanded support for advanced geospatial analysis and improved performance of spatial queries.
Hadoop is an open-source framework for storing and processing large datasets in a distributed computing environment. It allows for the storage and analysis of datasets that are too large for single servers. The document discusses several key Hadoop components including HDFS for storage, MapReduce for processing, HBase for column-oriented storage, Hive for SQL-like queries, Pig for data flows, and Sqoop for data transfer between Hadoop and relational databases. It provides examples of how each component can be used and notes that Hadoop is well-suited for large-scale batch processing of data.
SQL Server allows for parallel processing to improve query performance. It uses multiple threads or workers that can run tasks such as reading, writing, and calculating in parallel across multiple CPU cores. The degree of parallelism (DOP) or number of threads used can be configured through settings like MAXDOP. Determining the optimal DOP requires testing different values and monitoring performance and waits to find the best setting for each workload type.
Common Errors That Effect Performance (Adi Cohen, Naya-Tech)
There are a few common errors that have a negative effect on performance. In this session we will review some of them, see why they impact performance and provide alternative solutions. Among the issues we will cover are:
· Misunderstanding of the query plan when using procedures
· Query plan differences between procedures and ad-hoc batches
· The differences between a temporary table and a table variable
· And many more…
Who is afraid of Columnstore Indexes? (Michael Zilberstein, DB-Art)
This talk describes new SQL Server 2012 feature called "columnstore index". In this session we will learn about the differences between columnstore indexes and B-Tree indexes we are used to work with. We will see when it is best to use and when not to use this new index. We will cover limitations that columnstore index imposes on the tables that use it and how to live with those limitations. Like in all my sessions, I won't let you go without some internals – how columnstore index is organized on a physical level and how Query Processor works this new type of index. And of course Demos, Demos, Demos…
Bi303 data warehousing with fast track and pdw - Assaf Fraenkelsqlserver.co.il
HP offers two solutions for data warehousing - Fast Track and Parallel Data Warehouse. Fast Track provides reference architectures using SQL Server for balanced deployments scaling from 8-80TB. Parallel Data Warehouse uses a massively parallel processing architecture to scale SQL Server deployments to petabytes of data. It uses a scale-out architecture with distributed data and query processing. This provides very high performance for large and complex workloads.
Trace flags are used to temporarily change SQL Server's behavior for debugging or diagnosing issues. This document discusses several trace flags including:
TF 652, 661, 834, 836 which disable certain SQL Server processes or enable large page allocations.
TF 1211, 1224 which avoid lock escalation. TF 1117 forces data files to auto grow equally. TF 1204, 1205, 1222 provide more information on deadlocks.
TF 1118 addresses tempdb contention. TFs 3226, 3014, 3004 provide more backup/restore details. TF 4199 enables query processor fixes. TF 3502 prints checkpoint messages.
The document provides explanations of these trace flags
