8 DBA, Databases, & Data Definitions

Group: DBA, Databases, & Data


Topic: DBA & Data

#1. ANSI - ANSI is an acronym for American National Standards Institute.
#2. ASCII - ASCII is an acronym for American Standard Code for Information Interchange. The ASCII set consists of 7-bit codes that represent 128 standard characters, including letters, numbers, and symbols. The first 128 characters in the ASCII set, the extended ASCII set, and the ANSI set are the same.
#3. BDE - BDE is an acronym for Borland Database Engine (previously referred to as IDAPI and before that it was ODAPI).
#4. Master Table - A master table in a multitable relationship is the primary table. For every record in the master table, there can be many records in the detail table. If you are only dealing with one table, then it is the master table. A detail table in a multitable relationship is the table whose records are subordinate to those of the master table. A detail table is also called a slave table, a child table, or a many table.
#5. Optimistic Locking - A locking mechanism that allows other users to edit a record that is currently being edited. Essentially, last in wins or edits are discarded usually with an error.
#6. Pessimistic Locking - A locking mechanism that prevents other users from entering edit mode on a record that is currently locked.
#7. Standard Delimited Format (SDF) - SDF is an acronym for standard delimited format. An SDF is a text file formatted in a particular style. Each field is enclosed in quotation marks and separated by a comma. Each line ends with a carriage return and a linefeed.
#8. Tab-delimited format (TDF) - In a Tab-delimited format (TDF) file, each field is delimited by a tab character. Each record is delimited with a carriage return and line feed. TDF has the advantages of being immune to commas and quotation marks within the data itself.
