The document provides information on how to use the Database Engine Tuning Advisor (DTA) in SQL Server. It discusses how DTA works with SQL Trace output to analyze workload queries and make recommendations such as adding or dropping indexes. It also describes the four main steps to an analysis using DTA: generating a workload, starting DTA and connecting to a database, selecting the workload, and specifying tuning options. Finally, it discusses how DTA evaluates the cost of queries against recommendations to identify indexes and partitions that could improve performance.
System Monitor is a Microsoft Windows utility that allows administrators to capture performance counters about hardware, operating systems, and applications. It uses a polling architecture to gather numeric statistics from counters exposed by components at user-defined intervals. The counters are organized in a three-level hierarchy of counter object, counter, and counter instance. System Monitor can be used to analyze hardware bottlenecks by monitoring queue lengths for processors, disks, and networks. It also helps optimize SQL Server performance by capturing events using SQL Server Profiler.

The counters are organized in a three-level hierarchy of counter object, counter, and counter instance. System Monitor can be used to capture counter logs for analysis to troubleshoot issues like bottlenecks. It is recommended to select counter objects instead of individual counters to ensure all necessary data is captured.
This document discusses SQL Server endpoints and security. It describes how endpoints control connections to SQL Server instances and define acceptable communication methods. Endpoints have transports like TCP and payloads that determine allowed traffic types. Access to endpoints can be controlled through permissions. Various endpoint types like for database mirroring have additional configuration options. The document also covers creating principals like logins and users, roles, and configuring the SQL server surface area to restrict features and harden security.
This document discusses database backup strategies and procedures in SQL Server. Some key points:
- SQL Server uses a backup engine optimized for speed to quickly grab database pages during a backup without regard to page order. Multiple threads can write pages simultaneously to backup devices.
- A full backup captures all used data pages in the database. Transaction log and differential backups capture only changed pages since the previous backups.
- Partial backups can reduce size by backing up only specific filegroups. File/filegroup backups allow restoring portions of a database.
- Maintenance plans provide a graphical tool for automating common backup and maintenance tasks like reindexing.
The document discusses how to automate tasks in SQL Server using SQL Server Agent. It describes how SQL Server Agent provides a scheduling engine for automating backups, maintenance tasks, and other processes. It explains how to create jobs composed of steps to execute tasks on a schedule. Job steps can run T-SQL, files, packages and more. Schedules can be defined to control frequency and timing of job execution. Failed jobs and steps are logged to help troubleshoot issues. Alerts can be configured to notify administrators of problems or trigger corrective actions.
Policy Based Management in SQL Server 2008 allows administrators to define standard configuration policies and enforce compliance across multiple database instances. Key components of PBM include facets, conditions, policies, targets, and categories. Facets define object types or configuration options that can be controlled. Conditions specify allowed values for facet properties. Policies enforce conditions and can be scheduled, prevent changes, or log violations. Categories group related policies and a mandate setting enforces compliance when an instance subscribes to a category.
Table partitioning allows large tables to be split across multiple filegroups to improve performance. A partition function defines the data ranges and a partition scheme maps those ranges to filegroups. Tables, indexes, and views can then be created on partition schemes. The SWITCH operator can move partitions between filegroups with minimal locking to archive old data or distribute it across storage.

The document discusses various aspects of indexes in SQL Server including clustered and nonclustered indexes, index architecture and design, maintaining indexes through page splits and rebuilding/reorganizing indexes. It also covers full text indexes and features such as contains, freetext, stoplists and thesaurus files.
The document discusses different data types that can be used when creating tables in SQL Server, including numeric, character, date/time, binary, XML, spatial, and hierarchyid data types. It provides details on the storage size and valid values for each data type. It also discusses considerations for choosing the appropriate data type based on the intended use and storage optimization.
The document discusses database recovery options in SQL Server, including recovery models (full, bulk-logged, simple), how they affect transaction logging and restore options. It also covers using minimal logging to improve bulk load performance and the PAGE_VERIFY option to detect damaged pages.
The document discusses configuring files and filegroups in SQL Server. It describes how SQL Server uses data files to store database contents and transaction log files to store transactions. It also discusses filegroups, which map database objects to files on disk. The document outlines the types of file extensions (.mdf, .ndf, .ldf) used and how the proportional fill algorithm works. It recommends best practices for configuring files and filegroups when creating a new database. The document also briefly discusses FILESTREAM, the tempdb database, and file naming conventions.

The document discusses how the brain functions through neural connections and networks, with different areas of the brain specialized for different cognitive functions like vision, motor skills, and language. As children develop and learn, their brains form new connections and pathways that support increasingly complex thinking skills and the ability to learn from experiences. Experience and learning shape how the brain is wired and how it continues to develop over the lifespan.
