bclearer-interop-services
A set of I/O and interop connectors for the bclearer framework. It provides adapters to read and write data between in-memory “universe” representations and a variety of storage, file formats, and application services.
Installation
pip install bclearer-interop-services
Key Features
- Dictionary Service Convert data to and from generic Python dictionaries (e.g., mapping objects to table dictionaries).
- DataFrame Service Utilities for standardizing, filtering, merging, and converting Pandas (and PySpark) DataFrames.
- Delimited Text Read/write CSV and other delimited formats.
- Excel Services Import/export Excel (.xlsx) files.
- JSON, XML, HDF5, Parquet Native serializers and readers for common data formats.
- Relational Database Services Access MS Access, SQLite, and other RDBMS via SQL interfaces.
- Document Store Services MongoDB and JSON file store support.
- Graph Services Neo4j connector and network analysis utilities.
- EA Interop Service COM-based, SQL, and XML import/export for Enterprise Architect models.
- Session & Orchestration Helpers to manage connections, sessions, and orchestrate multi-step data flows.
Basic Usage
Below is a simple example using the Dictionary and DataFrame services:
from bclearer_interop_services.b_dictionary_service.table_as_dictionary_service import TableAsDictionaryFromCsvFileReader
from bclearer_interop_services.b_dictionary_service.table_as_dictionary_service import TableAsDictionaryToDataFrameConverter
# Read data from a CSV file into a table-as-dictionary
reader = TableAsDictionaryFromCsvFileReader()
table_dict = reader.read('data/example.csv')
# Convert the table-as-dictionary to a Pandas DataFrame
converter = TableAsDictionaryToDataFrameConverter()
df = converter.convert(table_dict)
# Standardize column names and filter rows using the DataFrame service
from bclearer_interop_services.dataframe_service.dataframe_helper import DataFrameHelper
helper = DataFrameHelper()
df = helper.standardize_column_names(df)
df_filtered = df[df['status'] == 'ACTIVE']
