• Generating structured representations of information items: this process is called feature extraction and can include simple tasks, such as extracting words from a text as well as complex methods, e.g., for image or video analysis. • Generating structured representations of information needs: often this task is solved by providing users with a query language and leave the formulation of structured queries to them. This is the case, for example, for simple keyword based query languages, as used in

SQL: Structured Query Language is programming language is designed to managing data in relational database management system (RDBMS). CREATE TABLE: In Structure Query Language we use CREATE TABLE command to describe the layout of table. Computed Field: A field whose values you derive from existing database table is called a computed field. Computed field functions involve addition, subtraction, multiplication and division. Sub Query: Sub Query is query in a query. A Sub Query is usually

migration. If you have multiple Access databases you can map them to multiple SQL Server databases (or schemas) or to multiple schemas under the connected SQL Azure database. A data definition language or data description language (DDL) is syntax similar to a computer programming language for defining data structures especially database schemas. Schema objects do not have a one-to-one correspondence to physical files on disk that store their information. However, Oracle databases store

database are made in the form of a query, which is a stylized question. For example, the query SELECT ALL WHERE NAME = "SMITH" AND AGE > 35 requests all records in which the NAME field is SMITH and the AGE field is greater than 35. The set of rules for constructing queries is known as a query language. Different DBMSs support different query languages, although there is a semi-standardized query language called SQL (structured query language). Sophisticated languages for managing database systems
