Core Requirements Scalability and Performance Monitoring Stability Security

Core Requirements Scalability and Performance –SMP support (including hyperthreading) –Garbage collector [IB6,7] –Configuration parameters customization [IB7] SWEEP_QUANTUM, USER_QUANTUM, MAX_THREADS, ENABLE_HYPERTHREADING –Query execution multi-segment index selection [IB7] Duplicate index key storage and traversal [IB7] NULL index key optimizations New in 7.5!

Core Requirements Scalability and Performance (contd..) –Transaction optimization for OIT/OAT READ COMMITTED optimization [IB7] –Database pagesize and cachesize 16KB database pagesize New in 7.5! 128K cache pages New in 7.5!

Core Requirements Monitoring –Performance and Usage Monitoring support via Temporary tables and SQL [IB7] –InterBase Performance Monitor GUI tool integrated into IBConsole [IB7]

Core Requirements Monitoring Tables Table name TMP$ATTACHMENTS One row for each connection to a database TMP$DATABASE One row for each database you are attached to TMP$POOL_BLOCKS One row for each block of memory in each pool TMP$POOLS One row for each current memory pool TMP$PROCEDURES One row for each procedure executed since the current connection began TMP$RELATIONS One row for each relation referenced since the current connection began TMP$STATEMENTS One row for each statement currently executing for any current connection TMP$TRANSACTIONS One row for each transaction that is active or in limbo TMP$TRIGGERS One row for each trigger executed since the current connection began

Core Requirements Stability –Server stability #1 priority –Attachment shutdown via Performance Monitoring Temp tables [IB7] –Cancellation of Long Running queries via Performance Monitoring tables [IB7] –Client API for programmable Query (statement) cancellation [IB6.5] –better error reporting of problem applications in interbase.log [IB7]

Core Requirements Security –System schema security (different levels) [IB6.5] –Embedded User Authentication (EUA). (a.k.a. database-level security) New in 7.5!

Development options Connectivity SQL enhancements Usability Tight integration with other Borland Solutions

Development options Connectivity –vigorously developed InterBase Express (IBX) components for Borland RAD tools –Borland Data Provider for ADO.NET [IB7] –Extensive 3rd party support via other drivers such as OleDB, Perl DBI for InterBase, etc. –All of the above use underlying InterBase API library (unified interface) –type-4 JDBC driver for JAVA applications [IB7] –New INTL character set support [IB7]

Development options SQL enhancements –ROLE based SQL security [IB6] –Exact Numerics [IB6] –CASE, COALESCE, NULLIF New in 7.5! –subset selection from resultset using SQL ROWS (similar to TOP/LIMIT in other DBs) [IB6.5] –Global Temporary Tables New in 7.5! –Embedded User Authentication commands for Local Database security (extension) New in 7.5! –Larger metadata names [IB7]

Development options ROWS clause InterBase now supports a ROWS clause for SQL SELECT, UPDATE and DELETE statements. It has a general syntax of ROWS [TO ] [BY ] [PERCENT] [WITH TIES]. The ROWS clause can be used in isolation or (most often) in conjunction with the SQL ORDER BY clause. The WITH TIES clause must be used in conjunction with ORDER BY. The ROWS clause introduces three new InterBase SQL keywords: ROWS, TIES, and PERCENT.

Development options Usability –out-of-the-box IBConsole [IB6] –Management of multiple databases on multiple servers from single GUI instance –Windows GUI to Windows/Linux/Solaris servers –SQL statement execution –User management –License management –Database backup and analysis via InterBase Services API

Development options Usability (contd..) –integrated Performance Monitor for each database [IB7] –3rd party tools available for Data Migration and general use

Development options Tight integration with other Borland Solutions –InterBase Developer Edition comes *free* with RAD tools including Delphi, C++Builder, CBuilderX, JBuilder, C#Builder. –Connectivity providers for development and deployment including BDP (ADO.NET), IBX, dbExpress, JDBC –CTS 2.0 compliant JDBC driver for development with Borland Enterprise Server

Deployment flexibility Low Total Cost of Ownership Ease of Deployment EMBED. DEPLOY. RELAX

Deployment flexibility Low Total Cost of Ownership –Licensing new licensing packs unlimited-users license per CPU [IB7] buy only as many SMP licenses as you need [IB7] 50-user license [IB7] Development Edition (only with Borland RAD tools) [IB7] VAR discounts Resellers get good discounts for more deployment Activation file provided to circumvent registration
