Hyperion Essbase integration with ODI
The document provides steps to extract data from a Hyperion Essbase cube and load it into a relational database using Oracle Data Integrator (ODI). There are three methods for extracting data from Essbase - using a Calc script, Report script, or MDX query. The steps include creating a Calc script using the DATAEXPORT function to extract data to a text file, configuring the Essbase connection in ODI's topology, reversing the Essbase cube, establishing the target database connection, creating an ODI interface using the LKM Hyperion Essbase DATA to SQL knowledge module, and running the interface to load the extracted Essbase data into the relational database tables.
Mdst 3559-03-01-sql-php
This document discusses interacting with MySQL databases from PHP using the Zend framework. It provides a basic 4 step process:
1. Include the Zend database library
2. Connect to the database by creating a configuration array and using Zend's factory method
3. Pass SQL statements to the database connection object and store the results
4. Loop through the result set to output or format the data
Datamigration
This document discusses using Oracle's Data Pump utilities (expdp and impdp) to migrate Oracle schemas between databases. It notes that the older exp and imp tools will become obsolete. The solution outlined uses Data Pump to extract the schema from the production database using expdp, then import it into the target database using impdp. Several advantages of Data Pump are highlighted, such as improved performance, ability to restart failed jobs, and object selection capabilities. Steps provided include creating directories, running expdp to extract the schema, moving the dump file, and running impdp to import the schema into the target database. Remapping options with impdp are also discussed to change the schema or tablespace names during import.
How to implement “multiple database(db) connection” in rails3
This document outlines steps to implement multiple database connections in a Rails application. It describes editing the database.yml file to add a connection to an external "remoteapp" database. Models are then configured to establish this secondary connection by calling establish_connection in the model definition. This allows accessing and modifying data from the remote database similarly to local models.
Base1
The document provides information on creating and working with databases in OpenOffice Base. It discusses how data is organized in tables with records and fields, and the tools available in the Base window. It also provides steps for creating a new database or opening an existing one, creating tables using a wizard or design view, and creating forms using the form wizard to customize how data is entered and displayed.
Creating a database
The document discusses various Data Definition Language (DDL) commands in SQL such as CREATE, ALTER, and DROP for defining and modifying database structure. It explains how to create tables with columns, constraints, indexes and views. It also covers removing tables and altering table definitions by adding, modifying or dropping columns, constraints and indexes. Different database architectures like single, multi database and distributed databases are also summarized.
Creating database
The document discusses the steps for creating an Oracle database instance, including understanding prerequisites, configuring initial settings, and using tools like the Database Configuration Assistant. It covers choosing a database type and management method, authentication options, storage mechanisms, and file management techniques. The key aspects are installing Oracle software, using DBCA or scripts to create the database, selecting initialization parameters, and starting/stopping the database instance.
Steps of-creating-a-database
The steps to create a database involve analyzing data, categorizing it and dividing it into tables with field names and data types. Key steps also include creating tables with primary keys, establishing relationships between tables, entering data, designing forms and queries with criteria to generate customized reports. The process concludes with a final assessment of the database.

Database management system by Neeraj Bhandari ( Surkhet.Nepal )
A database is an organized collection of structured data stored electronically in a computer system. A database management system (DBMS) is a complex software system used to create and manage databases and properly maintain large and complex databases. A DBMS provides logical and physical views of the data and allows for different external views for different users. It also provides languages to define, manipulate and control access to the data.

How to analyze_table_through_informatica
The document discusses analyzing a table in Oracle using the ANALYZE statement through an Informatica workflow. It proposes creating a stored procedure to execute the ANALYZE statement, as developers may not have direct access rights. The stored procedure would take the table name and cascade option as parameters. Synonyms and grants would then allow the stored procedure to be called from Informatica's pre-SQL command to analyze the target table before lookups are performed.
