¿Cómo se crea un diccionario de datos en una base de datos?

How do you create a data dictionary in a database?

Below are the steps that teams need to take when creating a data dictionary:

1. Gather terms from different departments.
2. Give the terms a definition.
3. Find alignment.
4. Get support and sign off.
5. Centralize the document.
6. Upkeep the data dictionary.

Open Access, and then click the File menu’s “Open” button. Select a database for which you want to create a data dictionary, and then click “Open” to load the database into Access. Click the “Database Tools” tab, and then click the “Database Documenter” button, which is in the Analyze group of commands.

Execution

1. Download the files required for creating the data dictionary.
2. Edit the config.xml file to (See example in Appendix C – Configuration file)
3. Run the enclosed SQL script [create_data_dictionary_schema.sql] to create the repository database, table and load stored procedure in the SQL Server you specify.

A data dictionary is a collection of descriptions of the data objects or items in a data model for the benefit of programmers and others who need to refer to them. For example, a bank or group of banks could model the data objects involved in consumer banking.

There are two types of data dictionaries: active and passive. An active data dictionary is tied to a specific database which makes data transference a challenge, but it updates automatically with the data management system.

A Data Dictionary Definition A Data Dictionary is a collection of names, definitions, and attributes about data elements that are being used or captured in a database, information system, or part of a research project. A Data Dictionary also provides metadata about data elements.

Attribute Type/Data Type: Defines what type of data is allowable in a field. Common types include text, numeric, date/time, enumerated list, booleans, and unique identifiers.

Data dictionary contents can vary but typically include some or all of the following: A listing of data objects (names and definitions) Detailed properties of data elements (data type, size, nullability, optionality, indexes) Entity-relationship (ER) and other system-level diagrams.

Data dictionary is a file that defines the format of data in an ASCII flat file, the field names, their order, their data type and the byte positions they occupy in the file. You will notice that the field “Description” is the one that needs to be very clear and succinct.

This tutorial will show you how to quickly create a Data Dictionary for any of your SQL Server, Oracle or MySQL databases. A Data Dictionary is a documentation of your data (metadata) – structure and a description of tables and columns, relations and constraints. It helps anyone who wants to work with databases find and understand data.

They are created in the SYSTEM tablespace and must remain there. The data dictionary base tables store information about all user-defined objects in the database. Table B-1 lists required scripts, which are run automatically when you create a database using the Database Configuration Assistant.

When you use the Database Configuration Assistant to create a database, Oracle automatically creates the data dictionary. Thereafter, whenever the database is in operation, Oracle updates the data dictionary in response to every DDL statement. The data dictionary base tables are the first objects created in any Oracle database.

To view the definition a procedure in Object Explorer

1. In Object Explorer, connect to an instance of Database Engine and then expand that instance.
2. Expand Databases, expand the database in which the procedure belongs, and then expand Programmability.

Searching Source Code & Your Views in SQL Developer

1. Just check the ‘All Views’ toggle.
2. Clicking on the search result will open the object.
3. Ah, so that’s how they do it…
4. Select, alt+g, and ‘Go’ 🙂

A stored procedure in SQL is a type of pre-written code that can be stored for later execution and then used many times hence, saving time. It is a group of SQL statements that performs the task. The stored procedure can be invoked explicitly whenever required.

Below are the steps for using filter settings to find stored procedure.

1. In the Object Explorer in SQL Server Management Studio, go to the database and expand it.
2. Expand the Programmability folder.
3. Right Click the Stored Procedures folder.
4. From the right-click menu, select Filter in the right-click menu.

The sys.sql_modules system catalog view returns a row for each object that is an SQL language-defined module in SQL Server. In other words, you can use this view to return information about objects of various types, including functions, stored procedures, and of course, views. One of the columns returned with this view is called definition.

The collation of the object definition always matches that of the calling database context. OBJECT_DEFINITION applies to the following object types: TR = SQL trigger (schema-scoped DML trigger, or DDL trigger at either the database or server scope) System object definitions are publicly visible.

Schema name. Table name. Column name. Data type. For instance, varchar or decimal. Data type with information about scale/precision or string length. For instance, varchar (100) or decimal (8, 2). Nullable flag. “Y” if column is nullable, “N” if column is not nullable. Column default value. Primary key flag.

This means that metadata-emitting, built-in functions such as OBJECT_DEFINITION may return NULL if the user does not have any permission on the object. For more information, see Metadata Visibility Configuration. The SQL Server Database Engine assumes that object_id is in the current database context.
