Ingres, PostgreSQL / postgres

The Tools

  • The OpenSource SQL database Ingres Corporation "Ingres".
  • “postgresql-8.4.13-1-windows.exe” and “postgresql-9.0.8-1-windows.exe” are the latest editions for W2k ( Download: OldApps "PostgreSQL" ).
  • The installation of “postgresql-9.0.8-1-windows.exe” on W2k causes a warning at the end of installation “A non-fatal error occured during cluster initalisation. Please check the installation log in C:\Temp for details”.
  • Installation of Postgres 9.4:
    • Password for the database superuser (postgres) → e.g “admin”.
    • Port number → default port number is “5432”.
    • Locale to be used by the new database cluster → Locale ”[Default locale]”.

Tips&Tricks

  • Configuration suggestions:
    • Standard user: “postgres”. The password may be set during installation.
    • Standard SQL server port: “5432”.
    • For users in Germany:
      • Select the locale to be used by the new database cluster. Local “English, United Kingdom”. Do not set it to ”[Default locale]”.
      • If you use a Windows computer with local Windows settings for Germany ( e.g. ”,” as decimal mark ),
        • no matter if you use an English or German operating system,
        • and if you set the database locale to ”[Default locale”],
        • You will get all database messages in German language :-(.

NoSQL Databases with SQL interface

    • “Crate.IO has built a new breed of database to serve today’s mammoth data needs. Based on the familiar SQL syntax, Crate combines high availability, resiliency, and scalability”.
    • “Why choose Crate Data? You can build similar solutions by combining a medley of technologies, like Mongo, Elasticsearch, Hadoop, CouchDB, Riak, Redis, MySQL, Postgres ect.”.
    • “Crate is a data store with the benefits of a NoSQL document with powerful search ( Elasticsearch as library included ), accessable using SQL.
    • I met CRATE representative XING "Stephanie Hollenstein" on the Europython 2014 fair.

  • IBM DB2 Express-C - “Free to develop, free to deploy, free to distribute”.
  • DB2 Express Edition - “Easy to Use. Low Cost. Powerful”.
  • EN.Wikipedia "DB2" - “DB2 Express-C is also similar to the free versions of Oracle database and Microsoft SQL Server, except that DB2 Express-C has no limit on number of users or on database size”.
    • Limitations of IBM DB2 Express-C:
      • “Benutzung von max. 2 Kernen einer CPU (bzw. 4 Kerne mit zusätzlichem Wartungsvertrag)”.
      • “Benutzung von max. 2 GB Hauptspeicher (bzw. 4 GB mit zusätzlichem Wartungsvertrag)”.
      • “Diese Version hat keine Einschränkungen hinsichtlich der Größe der Datenbank und der Anzahl der Benutzer, ohne zusätzlichen Wartungsvertrag gibt es jedoch keine Replikation, 24/7-Support und komfortable Updates”.

Automatic Generation of SSIS Packages
Resources
  • The motivation for “Integration Services” and SSIS:
    • Graphical design process “by mouseclick”, to determine and to connect and configure data sources for data transfer to and from an Microsoft SQL Server.
    • Internally, the Integration Services use components ( DLLs ) of Micosoft SQL Server, e.g. for lookup and fuzzy logic.
    • The Integration Services generate SSIS packages, in XML-based DTSX format. SSIS packages and its XML code do not allow any flow control like for-loops and if-then-else like any programming language.
    • Its easy to generate a handful of SSIS packages by the graphical design tools of IS :-), but a nightmare if you must generate 1000 packages. The approach for IS automation is to generate the XML code by third-party tools, by an own script language which supports usual programing language structures like for-loops and if-then-else.
