Adds DbQuerySource, an IImportSource implementation that executes SQL
queries against the LotFinder database. Supports parameterized queries
using anonymous objects and configurable command timeouts.
Add transformer that combines JDE Julian date (CYYDDD) and time (HHMMSS)
columns into a single DateTime column. Includes static ParseJdeDateTime
method for direct date conversion.
Add a data transformer that removes specified columns from the data stream.
Columns are matched by name (case-insensitive) and multiple columns can be
dropped in a single transformer. Includes comprehensive tests using NSubstitute
for mock IDataReader.
Add core transformer infrastructure for the ETL pipeline:
- DataTransformerBase: abstract base class with virtual methods for
field count, names, types, values, ordinals, and null checking
- TransformingDataReader: IDataReader wrapper that delegates to
transformer, enabling on-the-fly data transformations
Add SqlScriptRunner class that implements IScriptRunner for executing
SQL scripts against the LotFinderDB cache database. Includes constructor
validation and configurable timeout support (default 1 hour).
Add the four core interfaces for the ETL pipeline:
- IImportSource: defines data sources for reading
- IDataTransformer: defines data transformation layer
- IImportDestination: defines data write destinations
- IScriptRunner: defines script execution capability
Move configuration options from Core/DataAccess/DataSync/ExcelIO to
dedicated Options folders within each project for better organization.
Update all references and tests accordingly.
Set up repository with legacy .NET Framework 4.8 source (OLD/),
new .NET 10 Blazor solution (NEW/), OpenSpec specifications,
documentation, and project configuration.
