Architects are Faced with Many Questions How should the architecture be tiered or layered? What GUI client technology should be used? Where should the business logic reside? Should the architecture be service based? What language should be used? What database should be used? Where should the servers reside on the network? What security capabilities are needed?

Architects are Focused on Application Architecture How should the architecture be tiered or layered? What GUI client technology should be used? Where should the business logic reside? Should the architecture be service based? What language should be used? What database should be used? Where should the servers reside on the network? What security capabilities are needed?

Should the architecture be service based? What language should be used? What database should be used? Where should the servers reside on the network? What security capabilities are needed? Should Java, C#, C++ be used? What about a scripting language like Perl, PHP? Is AJAX or Spring appropriate?

The Architecture Questions go on and on… ,[object Object],[object Object],[object Object],[object Object],[object Object]

Often overlooked, Database Middleware Plays a Critical Role ,[object Object],[object Object]

Anatomy of a DataDirect Driver ,[object Object]

Anatomy of a DataDirect Driver

Robust Language, Platform & Architecture Support ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Standards Based API DataDirect converts standards-based API calls to proprietary DB wire protocol Consistent support for all DB vendors (Oracle, SQL Server, DB2, Sybase, MySQL, etc.) & DB versions (Oracle 9i, 10i, etc.) Robust support for application languages, architectures & platforms supported

“ Codeless” Configuration ,[object Object],[object Object],[object Object],[object Object]

Emulation for Missing DB Functionality Application is abstracted from anomalies in the RDBMS DataDirect driver “emulates” missing functionality No change is required in the DB configuration to enable emulation ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],SQL Up-Leveling Without SQL Up-Leveling the developer writes different code for different DBs and versions With SQL Up-Leveling, writes single standard version of SQL that works for all DBs and versions

SQL Up-Leveling Example ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Connection Management Application code requests connection to DB. Application is completely abstracted from pooling logic – no application code required to leverage pool DataDirect allocates connections from pool when available, otherwise new connections are created DataDirect takes care of managing the pool Connection pooling has no dependencies on the underlying RDBMS ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Thread Protection Application can determine threading capability of network and server via call to DataDirect driver DataDirect driver returns threading information to the application DataDirect driver ensures calls to the DB are thread safe by leveraging the most efficient and safe threading model for the application

Statement Pooling Frequently used SQL statements executed by application enjoy performance benefits without modification to application code DataDirect allocates connections from pool when available, otherwise new connections are created Statement pooling has no dependencies on the underlying DBMS ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

[object Object],[object Object],[object Object],[object Object],[object Object],Standard Error Handling Developer only has to handle standard set of error codes DataDirect driver maps the DB specific error codes using an ANSI standard SQLState mapping DBMS returns vendor specific error codes that lock developers into a specific DB

ADO.NET “Invalid Password” Example ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Consistent Metadata Support ,[object Object],[object Object],[object Object],Developer works with metadata using consistent interface DataDirect driver returns metadata in a consistent fashion. DataDirect emulates missing or inconsistent metadata from the DBMS DBMS returns vendor specific metadata that lock developers into a specific DB

International Code Page Support Application code is not affected by code page used by the DB DataDirect converts the code page values from the client to the server Database can use code page of choice without affecting application ,[object Object],[object Object],[object Object]

Data Conversion Support ,[object Object],[object Object],[object Object],Application interaction with driver / DB is completely abstracted from individual data formats in the DB DataDirect driver load handles conversion to and from standards format and DB format No special DBMS configuration required to enable data conversion

Data Encryption across the Network Application code is not affected by use of encryption DataDirect negotiates the client side work involved with the SSL handshake sequence of events DataDirect supports the encryption capability provided by the RDBMS ,[object Object],[object Object],[object Object]

Flexible Authentication Support ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Socket Management ,[object Object],[object Object],[object Object],[object Object],All socket management effort is abstracted from the application DataDirect provides controls interaction to the network via the socket Standard wire protocol is leveraged by the DataDirect driver for interaction with the DB

Network Wire Management ,[object Object],[object Object],[object Object],[object Object],[object Object],Application is completed shielded from the network communication that is managed by the driver DataDirect provides optimal network management Standard wire protocol is leveraged by the DataDirect driver for interaction with the DB

Batching & Throughput Optimization ,[object Object],[object Object],[object Object],Application executes the batch update DataDirect controls the batch update capabilities based on the application configuration DBMS returns information via the driver based on the update status

Failover Support ,[object Object],[object Object],[object Object],[object Object],[object Object],Application interaction with driver / DB is completely abstracted from load balancing capability DataDirect driver manages failover No special DBMS configuration or environment (e.g., Oracle RAC) needed to enable client failover

Load Balancing ,[object Object],[object Object],[object Object],Application interaction with driver / DB is completely abstracted from load balancing capability DataDirect driver load balances connection requests based on random algorithm No special DBMS configuration required to enable client side load balancing

Distributed Transaction Support ,[object Object],Application submits update request DataDirect driver works in conjunction with transaction manager to commit / rollback transactions DBMS returns status of individual update

DB Vendor & Version Interoperability ,[object Object],[object Object],[object Object]
