• Keywords cannot be abbreviated
• Statements manipulate data and table definitions in the database
• SQL statements 

Management

• Information Management (Advanced E-Business Data Management)
– Extensive Markup Language (XML)
– Universal format for structured documents and data on the
Internet
– Embedded query and storage engine
– Extensive Query Language (XQL)
– Content generation from HML documents
– Interprets XQL queries
– Generates in memory access structures
– Management of External Non-Relational Content
– Proxy tables – full access to all information in the operating systems directory

• Permits the use of hybrid transaction processing/query environments to perform the following functions
– Adjust to cache of Index pages and data
– Significant reduction in I/O costs
– User priorities are provided
– CPU level resources can be controlled
– Resources for a query or batch are limited
– DBA’s can reconfigure the system without rebooting

• Row-level Storage Security
– Solves the problem of information filtering
– By incorporating an application called Application Context Facility
(ACF)
– DBA can set attribute values for application facilitated by the creation of triggers that run each time a user logs in
• Secure Socket Layer Support
– Sybase supports Secure Socket Layer
– Allowing for the use of encryption between database clients
– Protects data from unauthorized access
– Sybase utilizes digital certificates to authenticate servers and username/passwords

• Compressed Backups
– Reduction of archival cost
• SQL debugging
– Assist in application development
• Lightweight Directory Access Protocol (LDAP)
– Support for easier system management
• Component Integration
– Remote query optimization
– Heterogeneous data access
– Heterogeneous transaction support

RDBMS Selection

•Sybase Adaptive Server Enterprise: It is a powerful data management platform for mission - critical transactions, it is known for its flexibility, open standards and effective use of computing power.
•iAnywhere Solutions: It is a comprehensive package that provides data management and enterprise synchronization to enable the rapid deployment of distributed e-business solutions.
•Adaptive Server IQ : It is a high performance relational database to meet the needs of business intelligence.

• When it comes to your business - Sybase understands one size does not fit all.
• Sybase competitive advantage are based on the company’s 3 strategic initiatives:
• e-Business
• m-Business
• Vertical markets.

• Basic Sybase infrastructure includes- 2 processes, data server and back up server.
• Oracle includes: 5 processes - process monitor, db writer, checkpoint and log writer.
• Backup Capabilities: Sybase can perform a dump database operation when the database is online or offline. In oracle previous to Oracle 8, the only way to back up the database was through a cold backup.
• Recovery Attributes: In Sybase the load database command loads the designated database. In Oracle recovery is achieved by restoring the data files.

• Security Procedures: The initial id shipped with Sybase is
System Administrator (SA). User logins are added at the server level, and then granted access to each database.
Oracle is shipped with several built in accounts system.
• Data Types: In Sybase the supported data types include integer, decimal, float, money, char, varchar, and text types.
Oracle data types include number, char,varchar2, date, long raw, clob, and blob.
• Storage: In Sybase tables are stored in segments, In Oracle tables are stored in table spaces.

• Performance and Scalability: Sybase continues to break TPC benchmark records. Oracle has always been known for its speed and performance. Oracle 8 supports 15,000 active user connections.
• Pricing - In Sybase price per seat is average. Support is achieved by opening cases with the support team. In oracle price per seat is relatively higher.

• Better tech support.
• Cheaper to administer.
• Requires fewer system resources.
• Better documentation
• Owns 90% of the financial industry which speaks of its reliability and stability
• Use of transaction logs - has roll back and recovery transaction log features.
• Sybase can backup on the fly without taking table spaces.

• Sybase Certified Associate
• Sybase Certified professional Adaptive Server
Administration.

• Sybase has a much more efficient database engine
• On a typical 300 GB database with 500 users, ASE can save customer $1.4 million (hardware and software)
• We use about half as much disk space for same amount of data
• Our SMP records prove the efficiency of ASE. Oracle relies on lots of hardware for high performance
• Using Oracle would cost the customer more even if the software was free

• Independent study comparing disk usage:
