ASCII
─────────────────────────────────────────────────────────────────────
This stands for the American Standard Code for Information
Interchange, an international method of representing information in
computers. ASCII is pronounced "ask-key".
ASCII DELIMITED FILES
─────────────────────────────────────────────────────────────────────
ASCII DELIMITED files consist of records in which the fields are
bound by quotation marks and are separated from other fields by
commas. Each record is on a line by itself. Trailing spaces are
truncated. Date fields are written in the form YYYYMMDD.
Example ASCII DELIMITED format:
"Jones","Mary","123 Main Street","Georgia"
"Smith","Jerry","1964 Jones Avenue","Florida"
"Peterson","Paul","985 East Polk","California"
Because most other database management programs export database files
in ASCII DELIMITED format and because DDFile can import ASCII
DELIMITED files, any data can be used with DDFile without reentering
each record.
ASCII SDF (System Data Format) FILES
─────────────────────────────────────────────────────────────────────
ASCII SDF files, like DELIMITED files, store each record on a
line of its own. However, the fields and records maintain a preset
width. SDF files are sometimes referred to as FLAT files.
Example ASCII SDF format:
Jones Mary 123 Main Street Georgia
Smith Jerry 1964 Jones Avenue Florida
Peterson Paul 985 East Polk California
DATA
─────────────────────────────────────────────────────────────────────
A piece of information. Normally useless as an independent item. Can
be useful when combined or used with other data. For example, a phone
number is useless until it is conveyed in conjunction with other data
such as a name.
DATABASE
─────────────────────────────────────────────────────────────────────
A repository of stored information organized in such a way that
information is easily retrieved. An example of a computerized
database is a collection of RECORDS, each record having the same
template for input. An example of a non-computer database is the
phone book.
FIELD
─────────────────────────────────────────────────────────────────────
An item of information stored as part of a RECORD. Normally several
fields are used for DATA storage in a DATABASE RECORD. Each field is
used for a particular piece of DATA. There are 5 types of fields
allowable in a dBASE database file. They are:
Character (name, address, city, state, zip code, etc)
Numeric (dollar values with or without a decimal)
Date (dates stored in format MM/DD/YY)
Logical (these are true/false values i.e. T or F)
Memo (store up to 64,000 bytes of unrestricted data)
INDEX FILE
─────────────────────────────────────────────────────────────────────
An INDEX FILE consists of at least one field from a database. The
field is sorted alphabetically, numerically, or chronologically, and
with each entry in the field is the corresponding record number from
the database. The record number is used to reference the proper
record in the database. An index file is, in effect, a virtual sort
of a database, since none of the records in the database are sorted.
The "index file to database file" relation is much the same as the
index in a book to the location in the text. Index files have a
filename extention of NTX.
PROMPT
─────────────────────────────────────────────────────────────────────
Blinking cursor or highlighted menu command.
RAM
─────────────────────────────────────────────────────────────────────
An acronym for Random Access Memory. This is normally the computer's
main memory.
RECORD
─────────────────────────────────────────────────────────────────────
An integral unit of data items (FIELDS) that, when combined with
other records, makes up a database.
RECORD POINTER
─────────────────────────────────────────────────────────────────────
The current record position within a database file.
