  • Managing Tables Storing User Data There are several methods of storing user data in an Oracle database: Regular tables Partitioned tables Index-organized tables Clustered tables Note: Partitioned tables, index-organized tables, and clustered tables are covered in other courses. Regular Table A regular table (generally referred to as a “table”) is the most commonly used form of storing user data. This is the default table and is the main focus of this lesson. A database administrator has very limited control over the distribution of rows in a table.

  • Much of the file management functionality of Access takes place in the background and automatically saves most changes you make to a database. When Access does not save something for you automatically, you will be prompted asking if you want to save the changes to a particular object. However, Access does give you a bit of flexibility when it comes to saving different objects. We will explore this saving functionality in this lesson.

  • One key distinction is that business angels invest their own funds, unlike VC funds, who primarily invest funds committed by others (e.g. institutional investors). For this reason they typically invest in companies with which they can maintain close contacts (OECD, 2006). Furthermore, typically companies that receive BA financing are smaller (i.e. in terms of turnover – see also table 1 later in this text) than VC backed companies. Most of the companies that receive BA financing, do not receive VC financing at the same time.

  • Export and Import Utilities The Export utility provides a simple way for you to transfer data objects between Oracle databases, even if they reside on platforms with different hardware and software configurations. When you run Export against an Oracle database, objects (such as tables) are extracted, followed by their related objects (such as indexes, comments, and grants), if any. The extracted data is written to an Export file, which is an Oracle binary-format dump file that is typically located on disk or tape.

  • Classification of Indexes An index is a tree structure that allows direct access to a row in a table. Indexes can be classified based on their logical design or on their physical implementation. The logical classification groups indexes from an application perspective, while the physical classification is derived from the way the indexes are stored. Single column and concatenated indexes A single column index has only one column in the index key—for example, an index on the employees number column of an employees table.

  • Loading Data Several methods are available for loading data into tables in an Oracle database. Of the methods available Direct-Load insert and SQL*Loader are discussed here. SQL*Loader SQL*Loader loads data from external files into tables of an Oracle database. It has a powerful data parsing engine that puts little limitation on the format of the data in the datafile. Direct-Load insert Direct-load insert can be used to copy data from one table to another table within the same database.

  • Built-In Database Objects In addition to creating the database files, several other structures are created. Data dictionary: Contains descriptions of the objects in the database Dynamic performance tables: Contains information used by the database administrator (DBA) to monitor and tune the database and instance PL/SQL packages: Program units adding functionality to the database. These packages are created when the catproc.sql script is run after the CREATE DATABASE command. PL/SQL packages will not be discussed within the scope of this course.
