1. Who makes a good database administrator
Technical knowledge.
Business knowledge and awareness.
Organization skills.
Ability to prioritize..

2. Concept Technical knowledge:-
Familiar with host operating system configuration, storage devices, and networking.
Business knowledge and awareness:-
A good DBA typically understands the business context within which the database operates.
Organization skills:-
DBAs must work with a variety of people in an organization, relying on good communication skills to provide database help. On the technical side, DBAs must communicate with programmers and systems technicians to ensure that applications access a database properly.

3. Concept
Ability to prioritize:-
A good DBA must prioritize the resolution of issues based on factors such as service level agreements (SLAs) with the business for database services, the number of users and systems affected, and the degree to which the problems are affecting ongoing operations.

4. Daily Tasks of a Database Administrator
Auditing
Application Integration
Backup and Recovery
Business Intelligence/Data Warehousing
Capacity Planning
Change Management
Database Application Development
Data Modeling and Database Design
9 . Developing and Maintaining Best Practices
10. Maintaining Servers and Databases
11.Performance Tuning
12.troubleshooting database systems.

5. explanation
1 Auditing :- An emerging task of the DBA is to identify which users are accessing, inserting, updating, or deleting data 2 Application Integration :- DBAs often get involved in figuring out the best way to integrate applications. This may include creating custom applications, Transact-SQL scripts, or SSIS packages. 3 Backup and Recovery :- DBAs are responsible for developing, implementing, and periodically testing a backup and recovery plan for the databases they manage. 4 Business Intelligence/Data Warehousing :- One of the fastest growing areas for the DBA is Business Intelligence (BI) and data warehousing.

6. 5 Capacity Planning It is the responsibility of the DBA to watch data growth, and plan how best to deal with it. This may include archiving it, increasing the size of current hardware, or adding new hardware. 6 Change Management It is often the responsibility to the DBA to perform impact analysis before changes are made, implement changes, test changes, and document them. 7 Database Application Development Many DBAs are really application developers who specialize in writing code to directly access SQL Server. While this is most commonly done using Transact-SQL and stored procedures, it can involve writing other code that is used to access SQL Server data

7. 8 Data Modeling and Database Design The foundation of all efficient and scalable databases is good database design. DBAs often create database designs by performing needs / requirement analysis, creating a logical mode, and them implementing the physical model. 9 Developing and Maintaining Best Practices The better organized and managed the database operations, the more efficient they will be. Ideally, an organization’s best practices will be documented for all to read and follow. 10 Maintaining Servers and Databases SQL Server, and the databases running on them, need periodic maintenance in order to run efficiently. DBAs are responsible for ensuring all maintenance gets done on a timely basis.

8. 11 Performance Tuning It is the job of the DBA to monitor performance and to determine ways to optimize database performance. 12 Troubleshooting database systems Many database administration operations are reactive, in the sense that they involve taking action to troubleshoot and remediate a problem that has been identified.

9. Documenting Database Management Procedures
Configuration settings
Standard maintenance procedures and schedules.
Disaster recovery procedures.
Most DBAs are familiar with the systems they manage, and the tasks that must be performed on a day-to-day basis. However, even the best DBAs do not rely purely on their memory.
DBAs commonly compile and maintain. maintaining documentation for the database system is an important part of database administration. A detailed run book can be invaluable when a new DBA must take over responsibility for managing a database, or when an unexpected emergency occurs and the DBA is not
present to deal with it.

10. Introduction to the SQL Server Platform
SQL Server Components
Database Engine
Analysis Services
Integration Services
Reporting Services
Master Data Services
Data Quality Services
Full-Text Search and etc,

11. Database Engine:-
The SQL Server database engine is the heart of the SQL Server platform.
The Database Engine is the primary component of SQL Server .
Database Engine is a high-performance component responsible
The Database Engine component of SQL Server is the core service for storing, processing, and securing data. TheDatabase Engine provides controlled access and rapid transaction processing to meet the requirements of the most demanding data consuming applications in your enterprise. The Database Engine is the primary component of SQL Server It is the Online Transaction Processing
(OLTP) engine for SQL Server and has received further enhancements since SQL Server The
Database Engine is a high-performance component responsible for the efficient storage, retrieval, and
manipulation of relational and Extensible Markup Language (XML) formatted data.
SQL Server 2008’s Database Engine is highly optimized for transaction processing, but offers exceptional
performance in complex data retrieval operations. The Database Engine is also responsible for the controlled
access and modification of data through its security subsystem.

12. Analysis Services
1. delivers Online Analytical Processing (OLAP). 2. and Data Mining functionality for Business Intelligence applications. 3 .Handel large quantities of data.
Analysis Services delivers Online Analytical Processing (OLAP) and Data Mining functionality for Business
Intelligence applications. The Data Mining component of Analysis Services allows the analysis of large quantities of data. This
data can be ‘‘mined’’ for hidden relationships and patterns that may be of interest to an organization’s
data analyst. In fact, a well-known story about data mining involves Wal-Mart, Pop-Tarts, and hurricanes.
Data mining revealed that prior to a hurricane event, sales of Pop-Tarts, particularly strawberry
Pop-Tarts, would surge. In fact, they concluded that sales of strawberry Pop-Tarts before a hurricane
were seven times that of normal sales.

13. Integration Services Extract, Transform, and Load (ETL) tool.
A set of graphical tools and programmable objects for moving, copying, and transforming data.
A rich environment for moving and transforming data
SQL Server Integration Services (SSIS) is Microsoft’s enterprise class data Extract, Transform, and Load
(ETL) tool. SSIS was originally introduced in SQL Server 2005 as a significant re-design of SQL Server
2000’s Data Transformation Services (DTS). SSIS offers a much richer feature set and the ability to create
much more powerful and flexible data transformations than its predecessor, and this has been further
expanded in SQL Server As another component in SQL Server’s BI stack, SSIS provides a
rich environment for moving and transforming data from a variety of source and destinations systems.
SSIS 2008 includes performance enhancements, new ADO.NET components, and a new script environment
that integrates with Visual Studio Tools for Applications (VSTA).
Integration Services is a set of graphical tools and programmable objects for moving, copying, and transforming data. It also includes the Data Quality Services (DQS) component for Integration Services.

14. Reporting Services
Web Service–based solution for designing, deploying, and managing flexible, dynamic web-based reports, as well as traditional paper reports.
Reporting Services is implemented as a Web Service.
it does not depend on Internet Information Services (IIS).
SQL Server Reporting Services (SSRS) can publish reports to a Virtual Directory hosted by the SQL Server itself
Reporting Services is a Web Service–based solution for designing, deploying, and managing flexible,
dynamic web-based reports, as well as traditional paper reports. These reports can contain information
from virtually any data source. Although Reporting Services is implemented as a Web Service, it does
not depend on Internet Information Services (IIS). In fact, in SQL Server 2008, IIS is no longer used to
manage SQL Server Reporting Services. SQL Server Reporting Services (SSRS) can publish reports to a
Virtual Directory hosted by the SQL Server itself, or to a SharePoint library. More information about
SSRS can be found in Chapter 18.

15. Master Data Services
SQL Server Master Data Services (MDS) provides tooling and a hub for managing master or reference data.
MDS can be configured to manage any domain (products, customers, accounts) and includes hierarchies, granular security, transactions, data versioning, and business rules

MDS can be configured to manage any domain (products, customers, accounts) and includes hierarchies, granular security, transactions, data versioning, and business rules, as well as an Add-in for Excel that can be used to manage data

16. Data Quality Services Full-Text Search
SQL Server Data Quality Services (DQS) is a knowledge-driven data quality tool for data cleansing and matching.
Full-Text Search
Full-Text Search is a feature of the database engine that provides a sophisticated semantic search facility for text-based data.

17. SQL Server Instances By default instance name is MSSQLSEVER
Two types of SQL Server
Default instance
Named instance
An SQL Server instance is a complete SQL server and you can install manyinstances on a machine but you can have only 1 default instance. An SQL Server instance has its own copy of the server files, databases and security credentials.
only a single copy of SQL Server could be installed on a server system. SQL
Server was addressed by the name of the Windows server on which it is hosted. To maintain backward
compatibility, this mode of connection is still supported and is known as the default instance. In internal
configuration tools, a default instance of the database engine is named MSSQLSERVER.

18. SQL Server Editions Enterprise Business Intelligence Standard Express
