The demands of business applications have pushed a technology explosion within SQL Server. SQL Server used to be a reasonably straightforward product consisting of a Database Engine for online transaction processing OLTP along with replication components to distribute data. Over several product cycles, SQL Server has evolved into a far-reaching data platform capable of servicing data storage, manipulation, and presentation needs across an enterprise.
In this chapter, you will learn about the core components of the SQL Server data platform. Database Engine services enable you to build high-performance database applications for online transaction processing OLTP and to support online analytic processing OLAP. To improve query performance, you can create and maintain indexes. You can split large tables and indexes across multiple storage structures by leveraging partitioning.
Database Snapshots allow you to quickly generate a point-in-time, read-only copy of any database. Multi-user access to data is arbitrated through the locking and transaction management capabilities to ensure consistent data access. To protect your data against catastrophic loss, you can back up all or a portion of a database along with having capabilities to restore data which has been damaged. While not an all-inclusive list, some of the elements of the storage engine that are explained in this book are shown in Table SQL Server can control the way clients are allowed to authenticate by enforcing that only Windows credentials be used or SQL Server internal logins allowed.
You can enable or disable various features of the SQL Server engine to ensure that only the subset of features necessary to support your applications is available. You can protect data stored within your databases by encryption through C A complete auditing system is available to track the use of elevated permissions as well as any permission changes that might be assigned.
Code can be modularized, stored on the server, and accessed from your application by leveraging views, stored procedures, functions, and triggers. Full-text search capabilities allow you to build query interfaces across large volumes of unstructured text data. Replication Almost from its inception, SQL Server has been able to distribute copies of data as well as keep all of the copies synchronized with the master data set.
Over the years, the distribution capabilities of SQL Server have expanded from maintaining multiple, read-only copies to C Through snapshot replication, the replication engine includes support for making periodic snapshots of a data set that are applied to multiple machines. After application of an initial snapshot, transactional replication transfers incremental data changes from the publisher to each subscriber. Transactional replication also has additional capabilities: allowing changes to be made at a subscriber and synchronized back to a publisher, and letting a peer-to-peer architecture be implemented whereby many instances of SQL Server can replicate to each other as peers.
Merge replication allows mobile, disconnected users to take local sets of data with them, make changes locally, and then synchronize all of the changes with the server. With failover clustering, the entire instance is protected in the event of a hardware failure. Database mirroring can be run in a synchronous mode, thus ensuring that no transaction will ever be lost due to a failure of the primary database. Within an instance, you can apply database mirroring, log shipping, and replication to provide redundant copies of entire databases or subsets of databases that can be used in the event of a failure on the primary database platform.
The high-availability features available in SQL Server are covered in more detail in Chapter As the role of IT has exploded within businesses, so have the number and scope of data storage applications. You may have customer information spread across dozens or hundreds of databases on various database management system DBMS platforms. You also may have supporting sales information stored in a variety of spreadsheets and customer communication could be spread across various e-mail systems and contact management applications.
Manufacturing schedules could exist within various project management and enterprise resource planning ERP systems. To utilize all of the operational data produced within any organization, there is a need to bring large amounts of information, spread across disparate systems, into a single, consistent set of data. The goal of the services provided by the business intelligence platform is to C Specialized tasks are included to copy SQL Server objects around an environment, as well as manage database backups, re-indexing, and other maintenance operations.
You can scrub invalid data, perform extensive calculations, and convert data types as the data moves through a pipeline.

If SSIS does not have a data adapter capable of handling the format of your data source or data destination or does not have a transform capable of the logic that you need to perform, a script component is included that allows you to bring the entire capabilities of Visual Studio Tools for Applications to bear on your data. NET or C.

Therefore, end users need tools to be available that can create standardized reports which will be available throughout the organization as well as provide the ability for end users to build reports on an ad hoc basis. The IT department can also design and publish report models that allow end users to build their own reports without needing to understand the underlying complexities of a database.
Reports built by IT, as well as by end users, can be deployed to a centralized reporting portal that allows members of the organization to access the information they need to do their jobs. For example, a sales manager can create a subscription to a daily sales report such that the report is generated at midnight after all sales activity is closed out, have it rendered in a PDF format, and dropped in his e-mail inbox for review in the morning.

The report server is responsible for hosting all of the reports and applying security. Rendering a report is accomplished either on demand from a user or through a scheduled task which allows the report to be run during off-peak hours.
Report Designer is responsible for all of the activities involved in creating and debugging reports. Included components allow users to create a wide range of reports from simple tabular or matrix reports all the way to reports with multiple levels of subreports, nested reports, charts, linked reports, and links to external resources. Within your reports, you can embed calculations and functions, combine tables, and even vary the report output based on the user accessing the report.
Report Designer is also responsible for designing reporting models that provide a powerful semantic layer to mask the complexities of a data source from end users so that they can focus on building reports. At the same time, IT does not have the resources to provide the hundreds of reports necessary to allow people to manage a business. You can include multiple dimensions, multiple hierarchies within a dimension, and choose a variety of options such as which attributes are available for display and how members are sorted.
By adding KPIs, you can provide visual cues for end users on the state of a business entity. The built-in metadata layer allows you to specify language translations at any level within a cube so that users can browse data in their native language. In this chapter, you will learn about the editions that are available and the corresponding hardware requirements. After installing, you will learn about the post-installation steps that should be taken.
Note You will need administrative authority on the machine where SQL Server will be installed to complete the steps in this chapter.
Each edition is tailored to meet an assortment of needs based on the features required for various applications within an organization. Table on page 16 lists the available editions of SQL Server. The Developer edition can be used only to develop SQL Server applications and cannot be used for production. The Evaluation edition is time-limited to days and can be used to evaluate SQL Server capabilities, but cannot be used in production or to develop applications.
Workgroup Suitable for departmental use or small organizations that need the basic functionality of a data management platform. Express Free and redistributable with applications to provide local data storage. It can also be used as a basic server-based data storage platform.
Express with Advanced Services All of the capabilities of the Express edition plus limited Reporting Services capabilities along with an Express version of Management Studio. Compact Free, redistributable embedded database built primarily for stand-alone applications. For example, the Enterprise edition is the only edition that supports Data mining, partitioning, Database Snapshots, online or parallel maintenance operations, compression, resource governor, peer-to-peer replication, hot add hardware support, unlimited CPUs, and up to 16 nodes for failover clustering.
The bit version can only be installed on bit versions of Windows. In addition to installing a supported operating system, you will need to ensure that the. NET Framework 2. SQL Server also requires 1. Click Start, right-click My Computer, and select Manage. Expand Local Users and Groups, and select Users. Right-click in the right-hand pane, and select New User.
Repeat steps 3 and 4 to create the service accounts listed in Table You will need to make appropriate adjustments for the Windows version that you are using. Additionally, if your machine is a member of a domain, your service accounts should be domain accounts, instead of local accounts, when installing SQL Server in any operational environment.
Collation Sequences Collation sequences control how SQL Server treats character data for storage, retrieval, sorting, and comparison operations. SQL Server allows you to specify a collation sequence to support any language currently used around the world. You can install one instance as the default instance along with up to 49 additional named instances or you can install 50 named instances.
When you connect to a default instance of SQL Server, you use the name of the machine that the instance is installed to. Note Only the Enterprise edition of SQL Server supports the installation of multiple instances on a single machine. SQL Server will perform the following actions during an in-place upgrade: C The previous SQL Server or instance will no longer exist on the machine. While a side-by-side upgrade involves many more steps that have to be performed manually, it has the advantage of leaving SQL Server or instance intact.
The side-by-side upgrade allows you to move databases to SQL Server in a staged manner. Note You cannot upgrade system databases using a side-by-side upgrade method. Backup and restore 2. Detach and attach 3. The Copy Objects Wizard allows you to specify the database objects along with the migration settings that are used.
