Mission Statement

• Sybase databases are developed to accommodate business needs regardless of size. The main focus of the database is Web based to allow portability, integration, manageability, and availability of applications as their dedication to businesses success.

Mission Objective

1. Provide high performance, scalable products that are compatible and deliverable anywhere.

2. Provide the most comprehensive solutions for processing of critical information globally.

History of Sybase

• Corporation located in Emeryville, Ca.

• Company founded in 1984.

• Sybase is primarily a UNIX vendor and is recognized as one the largest providers of database software.

• Introduced the SQL server in 1987 as a client server solution that was as designed to separate the client and server functionality.

ASE Environment

Common Database Architecture

Database Architecture

• Mixed and Varying Workloads

• Leverage Legacy Data

• Enterprise connect

• Replication Server

• Internet-Architecture Support

• Low and High-end Scalability

Data Type

• Having standard data type SQL2. However, there are quite a few exceptions.

SQL Statements vs. SQL*Plus Commands

SQL:• Is a language• Is ANSI standard• Keywords cannot be

abbreviated• Statements manipulate data

and table definitions in the database

• SQL statements SQL Buffer

SQL* Plus

• Is an environment

• Is Oracle propriety

• Keywords can be abbreviated

• Commands do not allow manipulation of values in the database

• SQL*Plus commands NO SQL*Plus buffer

Basic SQL

• Data Retrieval SELECT

• Data Manipulation Language (DML) INSERTUPDATEDELETE

• Data Definition Language (DDL) CREATE

ALTERDROPRENAMETRUNCATE

• Transaction control COMMITROLLBACKSAVEPOINT

• Data control language (DCL) GRANTREVOKE

DDL - Create table

• CREATE TABLE EMPLOYEE(FNAME VARCHAR(15) NOT NULL.MINT CHAR,LNAME VARCHAR(15) NOT NULL,SSN CHAR(9) NOT NULL,BDATE DATE,ADDRESS VARCHAR(30)SEX CHAR,SALARY DECIMAL(10,2),DNO INT NOT NULL,PRIMARY KEY (SSN) REFERENCES EMPLOYEE(SSN),FOREIGN KEY (DNO) REFERENCES DEPARTMENT(DNUMBER));go

DML - Insert data into table

• INSERT INTO EMPLOYEE

VALUES (‘Rich’,’k’, ‘Martin’,’123456789’,’1962-05-09’, ‘123 Main St, Baltimore, MD’, ‘M’, 37000, 15);

go

DATA RETRIEVAL - SQL

SELECT DNAME, COUNT(*)

FROM DEPARTMENT, EMPLOYEE

WHERE DNUMBER=DNO AND SALARY > 50000

GROUP BY DNAME

HAVING COUNT (*) > 5;

Data 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

Dynamic Performance Tuning

• 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

Security

• 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

Mission Critical Computing

• 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

SYBASE PRODUCTS

•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.

MERITS OF SYBASE

• 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.

SYBASE - ORACLE

• 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.

SYBASE - ORACLE

• 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.

SYBASE - ORACLE

• 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.

SYBASE vs. ORACLE

• 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 - CERTIFICATIONS

• 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

• Oracle had to spend two times as much to get only 9% more performance

• Oracle ran on six times as many processors (96 vs. 16) to get only 9% more performance

• If you want to spend more on hardware & maintenance buy Oracle. Sybase is the performance and scalability leader

Conclusion

• A True Relational Database

• Follows the SQL2 standards

• Rank 3nd in RDBMS

• Easier to use and learn than Oracle

• Similar features and structures as Microsoft SQL 2000

• Lower price in comparing to other DBMS
