CREATE INDEX Tips Using DOMAIN Type Indexes. New in Oracle 8i is the DOMAIN index. A DOMAIN index is actually an extension to the Oracle index system that allows a developer (this is usually done by companies developing commercial applications or cartridges) to create their own index type. Index types are created using the CREATE INDEXTYPE command.

1 Introduction to the Oracle Database Oracle Database Architecture. An Oracle database is a collection of data treated as a unit. The purpose of a database is to store and retrieve related information. A database server is the key to solving the problems of information management. data dictionary is created when a database is created. To accurately reflect the status of the database at all times, the data dictionary is automatically updated by Oracle in response to specific actions, such as when the structure of the database is altered.

The Black Art Of Spatial Index Tuning In SQL Server A SQL Server spatial index is basically a grid of cells that cover the extent of the spatial data in a table which allows spatial queries to easily filter out prospective records and lookup smaller subsets of records to see if they match the spatial criteria.

Oracle Concepts - RDBMS Architecture Oracle8i provides new features in the object-oriented extensions provided in Oracle8 as well as to the Oracle RDBMS. In an object-relational database, columns can represent either a single value (as in standard relational databases), a varray (a fixed number of additional records), or a REF to a second table where a variable amount of data can be stored.

Schema Oracle Database (DB) refers to schema as a user collection of database objects. The schema and user names are the same but function quite distinctly; i.e., a user may be deleted or reassigned to another user while its collection of objects (schema) within the database remains intact.

4 Using Indexes in Database Applications When to Use Function-Based Indexes. A function-based index computes the value of an expression that involves one or more columns and stores it in the index. The index expression can be an arithmetic expression or an expression that contains a SQL function, PL/SQL function, package function, or C callout. Function-based indexes also support linguistic sorts based on collation keys, efficient linguistic collation of SQL statements, and case-insensitive sorts.

25 Overview of Application Development Languages Overview of Oracle Call Interface (OCI) The Oracle Call Interface (OCI) is an application programming interface (API) that lets you create applications that use the native procedures or function calls of a third-generation language to access an Oracle database server and control all phases of SQL statement execution.

Domain Name System A reverse lookup is a query of the DNS for domain names when the IP address is known. Multiple domain names may be associated with an IP address. The DNS stores IP addresses in the form of domain names as specially formatted names in pointer (PTR) records within the infrastructure top-level domain arpa.nternet name servers and a communication protocol implement the Domain Name System. A DNS name server is a server that stores the DNS records for a domain name; a DNS name server responds with answers to queries against its database.

Turbocharge SQL with advanced Oracle indexing Oracle uses a specialized optimizer method called a bitmapped index merge to service this query. In a bitmapped index merge, each Row-ID, or RID, list is built independently by using the bitmaps, and a special merge routine is used in order to compare the RID lists and find the intersecting values.

How do database indexes work? And, how do indexes help? Provide a tutorial on database indexes. Well, an index is a data structure (most commonly a B-tree) that stores the values for a specific column in a table. An index is created on a column of a table. So, the key points to remember are that an index consists of column values from one table, and that those values are stored in a data structure.

REIT Dividends Are Like Snowballs: All You Need Is Wet Snow And A Long Hill Accordingly, any company that qualifies as a REIT is permitted to deduct dividends paid to its shareholders from its corporate taxable income. But more often, most REITs remit at least 100 percent of their taxable income to their shareholders and therefore owe no corporate tax. In a previous Seeking Alpha article I explained the value proposition (for REITs): It's not hard to see why investors are attracted to the idea of high-dividend-paying stocks.

1 Introduction to the Oracle Database Every Oracle database has one or more physical datafiles, which contain all the database data. The data of logical database structures, such as tables and indexes, is physically stored in the datafiles allocated for a database.

Oracle NUMBER: Precision and scale The Oracle Concepts guide states that the NUMBER datatype stores fixed and floating-point numbers. A column with the NUMBER datatype can be defined as follows: column_name NUMBER (precision, scale) The precision defines the total number of digits. The scale defines the number of digits to the right of the decimal point. If you specify a negative scale, Oracle Database rounds the actual data to the specified number of places to the left of the decimal point. For example, specifying (7,-2) means Oracle Database rounds to the nearest hundredths .

Turbocharge SQL with advanced Oracle indexing An Oracle b-tree index. Oracle offers several options when creating an index using the default b-tree structure. It allows you to index on multiple columns (concatenated indexes) to improve access speeds. Also, it allows for individual columns to be sorted in different orders.

array Note: Internally, uninitialized entries of an array of domain type DOM_ARRAY have the value NIL. Thus assigning NIL to an array entry has the same effect as deleting it via delete. Afterwards, an indexed call of the form A[index] returns the symbolic expression A[index], and not NIL. See Example 5.
