oracle designer 6i
Oracle Designer 6i

Pros

  • Metadata (Designer's data) is stored in a repository in an Oracle database
  • Designer takes care of all your development needs - data modeling, function modeling, site-specific server implementation (including stored PL/SQL) and development.

  • Seamless integration with Oracle database
  • Discoverer EUL can use OWB repository

Concerns

  • Only supports Oracle databases as target
  • Does not share common repository
  • Scheduling is cumbersome and requires OEM which is not DBA friendly as it distributes secure access
  • OWB runtime has to be installed on individual target schemas (test, stage, target, etc.)
  • Key lookup function is weak compared to industry leaders (i.e., does not deal with duplicate keys)
  • OWB Aggregator has bugs when an update to the mapping is made, this anomaly has not been resolved even in the latest release.

future
Future
  • 9i OLAP
      • No separate DB.
      • SQL & Java beans access
      • Aggregation – non additive
      • Regression & forecasting
      • YTD calculations
  • 9i data mining

Integrate data mining within DB for faster reads and incorporate DM4j components of JDeveloper.

      • Classification
      • Clustering
      • Decision trees
      • Market Basket Analysis
  • 9i compression

Compress snapshots data that is seldom used.

  • 9i ETL engine

Table functions to avoid staging tables, transportable tablespaces, resumable statements & parallal execution

  • 9i Streams

Once OLTP moves to 9i, plan on using oracle streams for real time DW. Streams read OLTP log file

  • 9i SSO and OID

Integrated with 3rd party LDAP, including Active Directory and database security.
