What It Is

Minimal LSAR Sandbox is a small desktop editor for working with data structured around MIL-STD-1388-2B. It is intended for learning, training, and limited technical checks.

Database: a local SQLite file using a 103-table LSAR schema.
Functions: table editing, relational navigation, search, and LCN tree inspection.
Data exchange: import and export of positional fixed-width text files.

How It Works

The application runs locally and keeps the database and exported files on the user's computer.

Local SQLite Database

Create a blank database or open an existing file. The SQLite engine is included in the standalone application; no account or database server is required.

Relational Checks

Foreign-key constraints and parent-child links help identify invalid references and navigate related records.

Fixed-Width Text Files

Import and export positional text files using the field widths defined for each table and column.

Main Functions

Relational grid editor showing the XB LCN indentured item table — Table Editor

Browse and edit the 103 tables in a spreadsheet-style grid. Tables are grouped by functional area, with row counts and parent references shown in the interface.

Live search filtering the HA item identification table — Search and Filtering

Filter the current table as you type and see how many rows match the search.

Status bar showing the selected column's type, width and constraints — Column Information

Select a cell to see the column type, fixed-width size, and primary- or foreign-key constraints.

Hierarchical LCN indenture tree of the physical breakdown — LCN Indenture Tree

View the Table XB indenture structure as a hierarchy and open the corresponding record from the tree.

Export dialog selecting tables to compile into a flat file — Fixed-Width Export

Select the tables to include and generate a positional text file using the configured field widths.
