The Tcl / Unibase Automation Blueprint
While Unibase eliminates standard application-level code through non-procedural tools, complex process automation tasks are supported natively via the Tcl Support Library. This wrapper interfaces directly with the Unibase data structures, combining low-overhead $O(1)$ memory mapping speeds with high-performance inter-system automation.
Core API Command Reference
The support library exposes specialized pipeline primitives, allowing existing enterprise processes to securely query transaction records and trigger calculations directly within memory contexts:
| Tcl Command | Syntax Parameters | Functional Execution Task |
|---|---|---|
ub_get_field |
ub_get_field [table] [record_id] [field] | Intercepts and fetches a specific string or numeric value directly out of the target schema layer. |
ub_put_field |
ub_put_field [table] [record_id] [field] [value] | Writes a state update to a cell, instantly invoking database dictionary layout constraints. |
ub_eval_calc |
ub_eval_calc [table] [set_name] | Forces the running Tcl environment to compute a specified Unibase Non-Procedural calculation sequence. |
Implementation Blueprint Example
The following example exhibits a clean Tcl block interacting with the core Unibase library to dynamically pull an account state, apply external business rules, and write back synchronized results:
package require UnibaseCore
set client_id “ACCD-9821”
set current_bal [ub_get_field customer_ledger $client_id balance]
# Enforce conditional rule processing using native Tcl primitives
if { $current_bal > 50000 } {
set new_tier “Platinum Plus”
ub_put_field customer_ledger $client_id membership_level $new_tier
ub_eval_calc customer_ledger sync_rates
}
This procedure bridges legacy environment data with the non-procedural dictionary layer without generating hidden technical debt.
Exception States & Validation Catch Points
If a value submission fails to satisfy the rules defined in the central Data Dictionary blueprint during a ub_put_field call, the Tcl library automatically intercepts the rejection state to prevent data corruption:
| ERR_DICT_BOUNDS | The submitted value string violates explicit length or character formatting parameters. |
| ERR_INTEGRITY_FAIL | Referential verification checks failed. The linked parent identifier does not exist. |
| ERR_LOCK_TIMEOUT | The transaction cell is undergoing concurrent mutation and dropped processing requests securely. |
