Talend Data Integration with 13 Assignments (From Azam)

Explore what data schema means in file and data management, define columns and data types, and compare manual schema definition with reading large files using metadata in Talend.

Use the tSchemaComplianceCheck component in Talend data integration to enforce schema rules, detect length violations, and route clean versus rejected records for remediation.

Parse comma-delimited flat files in Talend data integration, auto-deducing schema from centralized metadata, trim spaces, handle quotes, and validate data with length checks and rejection handling.

Explains how to parse multi schema files with positional, delimited, and Ximo parsers, identifying schemas and producing separate outputs.

Open a database connection in the pre job, reuse it through the integration, and close in the post job while reading, mapping, and writing with insert, update, or delete actions.

Use the Delane utility to retrieve and import table schemas from multiple tables into your database project, then work with the loaded schema in your creation jobs.

Discover how to use Talend's built-in SQL editor to test queries, explore tables, and view database schemas with auto-suggestions, before integrating into components.

Learn to use context and global variables in SQL queries within Talend data integration, including referencing context variables and globalMap.get for parameterized statements.

Execute multiple SQL statements in a single Talend database component by wrapping them in a begin...end block, enabling create, insert, and update statements to run together and streamline design.

Update multiple student records by using a database row component to apply full names to the existing first names, referencing row data and executing an update query to set student_name.

Explore the standard database joins in Talend, including inner, left, and right joins, plus outer join variants, and learn how to tune components to perform these joins.

Perform an inner join between the customer and orders tables using the customer_id key, mapping inputs with the dematte and deep map components to produce a combined, matched output.

Discover how to perform an inner join left table reject in Talend data integration using the Dematte component to extract left table rejections after joining customers and orders.

Apply a left outer join in Talend to include all left-table records, show matching right-side data, and display nulls for non-matches.

Learn to perform a right join in Talend data integration, returning all right-side records and nulls for nonmatches on the left, with hash output components for uniting results.

Learn to map, transform, and join data with the tMap component in Talend Data Integration, using lookups, expression builder, and multiple input/output configurations.

Explore a divide-and-conquer approach by transferring data from child jobs to a parent job, using a data dump and bofill components to merge independent results.

Explore how to manage for and while loops in Talend data integration, using the loop component to control boundaries, sub jobs, and context variables, with practical examples and break conditions.

Convert a data flow to an iterate flow by using the trade component to process each row individually, store values in a global variable, and feed results to downstream components.

Learn data normalization by turning a multi-valued sports column into separate rows to reduce redundancy, enable reporting and aggregation, and compare normalization with denormalization.

Learn how denormalization consolidates repeating columns into a single delimiter-separated column to reduce data redundancy and memory usage, illustrated with sports and city data and a merge duplicates option.

Discover how multicasting copies a data flow to multiple targets with the same schema, using a replicate component and a unique component to remove duplicates before writing to a database.

Learn how to remove duplicates in Talend using a unique component that evaluates three attributes (id, name, sport) case-sensitively, and review or log duplicates separate from uniques.

Discover Talend Exchange, a community platform where developers share free components, upload their own, and easily integrate them into Talend, offering more than 900 components for global use.

Sign in to Talend Exchange to download a component, extract the zip, place it in the Delane plug ins directory, and restart Delane to use the component in data flows.
