Following is a small database management system, originally written under a PDT-11. Is was meant to be relational, but author could not quite finish it up. It runs under IBM-PC. I also use it in under my PRO/VENIX for my record collection and number of other purposes. It seems to work fine for not-so-critical database needs. I am posting it due to some recent queries. This version came off an 84 DECUS tape. have fun. Oz ----------- SNIP SNIP SNIP ---------------------------------------- #!/bin/sh # This is a shell archive, meaning: # 1.

Smith X 44 Ole Musket Lane X Danbury, CT 06810 X (203) 748-5934 X X X 1.0 INTRODUCTION X X SDB is a simple database manager for small systems. It was X developed to provide a relatively low overhead system for X storing data on machines with limited disk and memory X resources. The current version runs on a PDT-11/150 with 2 X RX01 floppy disk drives and 60K bytes of memory under the X RT-11 operating system. (it also runs on the VAX under VMS) X X SDB was originally intended to be a relational database X system, so many of the terms used in describing it are taken X from the relational database literature. Within the context X of SDB the user can safely make the following associations: X X 1. RELATION can be taken to mean FILE X X 2. TUPLE can be taken to mean RECORD X X 3. ATTRIBUTE can be taken to mean FIELD X X It should be noted that SDB is not a relationally complete X system. It provides the relational operations of SELECT, X PROJECT, and JOIN, but does not provide the set operations X of UNION, INTERSECTION, or DIFFERENCE as well as some X others. X X X 2.0 RELATION FILE FORMATS X X SDB maintains a separate file for each relation that the X user creates. This file contains a header block containing X the definition of the relation including the names and types X of all of the relation's attributes. The remainder of the X file contains fixed length records each containing one tuple X from the relation. X X Tuples can be of three types: X X 1. active - tuples that contain actual active data X X 2. deleted - tuples that have been deleted X X 3. unused - tuples that haven't been used yet X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X SDB - a Simple Database System Page 2 X X X Initially, all tuples are unused. When a new tuple is X stored into a relation, the first unused tuple is found X (they are all contiguous at the end of the relation file). X The new tuple is stored as an active tuple. X X When a tuple is deleted, it is marked as such. The space X previously allocated to the deleted tuple is left unused X until the relation is compressed. X X It is possible that when attempting to store a new tuple, no X unused tuple can be found even though the relation contains X fewer than the maximum active tuples. This happens when X tuples have been deleted since the time the relation file X was last compressed. X X The compress function allows all of the space lost by X deleting tuples to be regained. It does this by copying all X of the active tuples as far backward in the file as possible X leaving all of the available space toward the end of the X file. X X X X 3.0 SELECTION EXPRESSIONS X X A selection expression specifies a set of tuples over which X some SDB operation is to be executed. The syntax for a X selection expression is: X X <rse> ::= <rnames> [ where <boolean> ] X <rnames> ::= <rname> [ , <rname> ] ... X <rname> ::= <relation-name> [ <alias> ] X X When a single relation name is specified in a selection X expression, each tuple within that relation becomes a X candidate for selection. X X When more than one relation name is specified, the tuples X are formed by taking the cross product of all specified X relations. If a relation is to be crossed with itself, an X alias must be given to one or both of the occurances of that X relation name in the selection expression. This allows SDB X to determine which relation occurance is being refered to in X the boolean part of the selection expression. X X After the set of candidate tuples is determined, the boolean X expression is evaluated for each candidate. The candidates X for which the boolean expression evaluates to TRUE become X the selected tuples. X X X X X X X X X X X X X X X SDB - a Simple Database System Page 3 X X X 4.0 INITIALIZATION FILE AND COMMAND FILES X X When SDB is first run, it attempts to read and process X commands from a file named "SDB.INI". This file usually X contains macro definitions, but can contain any valid SDB X command. In addition, it is possible to process command X files from within SDB. This is done by typing an '@' X followed by the command file name after the SDB prompt. X X X X 5.0 FILE NAMES X X Whenever a file name is allowed in the syntax for a command, X it is possible to use either an identifier or a quoted X string. An identifier is interpreted as the file name and a X string is interpreted as a full file specification. The X string form allows for the specification of an alternate X device or extension. X X X X 6.0 FORM DEFINITION FILES X X A form definition file contains a template into which X attribute values are substituted during a print operation. X There are two types of information that can be included in a X form definition: X X 1. Literal text X X 2. Attribute references X X Attribute references are indicated by placing the name of X the attribute being referenced between a pair of angle X brackets. Literal text is anything that is not enclosed in X angle brackets.

This is useful for relations, X when it is necessary to join a relation to itself. It is X useful for attributes when it is desired that the column X headers in a table be different from the actual attribute X names. Also, alternate attribute names can be used in X references to that attribute in the where clause as well as X in a form definition file. The syntax for specifying X aliases is: X X <name> <alias> X X X Example: X ________ X X print using test amount a,category c from checks; X X Where test.frm contains: X X Amount: <a> X Category: <c> X X X X X X X X X X X X X X X X X X X X X X X X X X X X SDB - a Simple Database System Page 5 X X X 8.0 BOOLEAN EXPRESSIONS X X The syntax for boolean expressions: X X <expr> ::= <land> [ '|' <land> ] X <land> ::= <relat> [ '&' <relat> ] X <relat> ::= <primary> [ <relop> <primary> ] X <primary> ::= <term> [ <addop> <term> ] X <term> ::= <unary> [ <mulop> <unary> ] X <unary> ::= <factor> | <unop> <unary> X <factor> ::= <operand> | '(' <expr> ')' X <operand> ::= <number> | <string> | <attribute> X <attribute> ::= [ <rname> . ] <aname> X <relop> ::= '=' | '<>' | '<' | '>' | '<=' | '>=' X <addop> ::= '+' | '-' X <mulop> ::= '*' | '/' X <unop> ::= '+' | '-' | '~' X X X Operators: X X 1. '=' - equal X X 2. '<>' - not equal X X 3. '<' - less than X X 4. '>' - greater than X X 5. '<=' - less than or equal X X 6. '>=' - greater than or equal X X 7.
