A Digital Signature is Code that uses cryptography to verify the authenticity of a source of information.
Installing Linux Binary Distributions Using RPM
• Two categories of RPM packages :

• Platform specific - linked dynamically to libraries that are found on the specific platforms
for which they are built.
• Non-platform specific - statically linked to Linux threads.
Choose one of three server configuration types:
• Developer- developmental use only, used to develop, build, and deploy applications
• Server- intended to house several other server applications
• Dedicated- used only as a MySQL database server
Choose the way the database will be used:
• Multifunctional - general-purpose use, will enable both InnoDb and MyISAM storage engines to be
available simultaneously
• Transactional - enable both InnoDB and MyISAM engines, MyISAM does not support transactions.
• Non-transactional- used for simple web applications and monitoring capabilities. InnoDB disabled.
If you cannot disable remote access, you should secure the MySQL server behind a firewall.
You should implement different logins for each application because If an intruder breaches the system,
having different logins for each application can isolate and minimize the damage.
The root user has full privileges on a MySQL server.
CHAPTER 4 SQL SERVER INSTALL
Supported platforms for Microsoft SQL Server are dependent on their edition.
When a 32-bit version of SQL is placed on a 64-bit operating system, the platform is forced to run the
database server in 32-bit mode.
Software required to enable installation of 32-bit and 64-bit Microsoft SQL Server editions:
• Shared Memory
• TCP/IP
• Named Pipes
• Virtual Interface Adapter Via Protocols
SQL Server data is stored, retrieved, and manipulated within a client-server architecture.
Network design and architecture play large role in reliability and efficiency of the client-server
environment.
Available editions:
• SQL Server Express Edition - free, lightweight version of SQL Server 2008. Recommended for
personal and individual use.
• Compact 3.5- skinny version of SQL Server 2008, free edition created for mobile devices and
mobile application developers.
• Workgroup Edition -intended for a department or small business use, ideal for environments
that require small user data storage or web applications that have minimal usage.
• Web Edition - built for a large amount of traffic, ideal for full web hosting.

• Developer Edition -same features as full enterprise, to be used for development and testing only,
not intended for production.
• Standard Edition -can be used in small to large organizations where server redundancy is not
required, but usage is significant and integration services are needed.
• Enterprise Edition -complete feature set, most scalability, ideal for large workloads and frequent
usage. Features include: partitioned table parallelism, database mirroring, online indexing,
online page restore, extensible key management, failover clustering, transparent database
