About the Asociado en SQL y Modelado de Datos certification

Una certificación de nivel asociado que convierte la sintaxis SQL en juicio real de consultas y modelado. Aprenderás a escribir sentencias SELECT precisas con filtrado, ordenación y limitación; agregar con GROUP BY y HAVING; combinar tablas con todos los tipos de JOIN (INNER, LEFT, RIGHT, FULL, SELF, CROSS); descomponer problemas con subconsultas y CTEs; clasificar, desplazar y acumular con funciones de ventana (ROWNUMBER, RANK, LAG, LEAD, totales acumulados); combinar conjuntos de resultados con UNION, INTERSECT y EXCEPT; y modificar datos de forma segura con INSERT, UPDATE y DELETE. En el lado del diseño dominarás el modelo relacional, el modelado entidad-relación (entidades, atributos, relaciones, cardinalidad), las restricciones que protegen la integridad (claves primarias, claves foráneas, UNIQUE, CHECK, NOT NULL), índices y los fundamentos del rendimiento de consultas, transacciones y ACID, las sutilezas de NULL, la normalización a través de 1FN/2FN/3FN/BCNF y la desnormalización deliberada, los esquemas en estrella frente a los de copo de nieve para analítica, y las claves sustitutas frente a las naturales. Las habilidades son independientes del motor — cada concepto se aplica limpiamente sobre PostgreSQL, MySQL, SQL Server y Oracle — por lo que se transfieren dondequiera que vivan tus datos.

What you will learn

The official Asociado en SQL y Modelado de Datos study course covers:

Querying with SELECT — Reading data precisely: SELECT/WHERE/ORDER BY/LIMIT, operators and NULL handling, and the logical order the database actually evaluates a query in.
Aggregation and Joins — Summarising data with GROUP BY/HAVING and combining tables with every JOIN type — the heart of multi-table SQL.
Subqueries, CTEs, Windows, and Sets — Composing advanced queries: nested and correlated subqueries, CTEs (including recursion), window functions, and set operations.
Relational Design and Integrity — The relational model and ER modelling, the constraints that protect data, indexes and performance, and transactions with ACID.
Normalization and Analytics Modeling — Normal forms 1NF-BCNF and when to denormalize, plus dimensional modelling: fact and dimension tables, star vs snowflake schemas.
