In the two sections that follow you will see two ways of creating a dictionary. Find the number of key-value pairs contained in a dictionaryĪ dictionary in Python is made up of key-value pairs. You will also learn some of the most common built-in methods used on dictionaries.ġ. You will learn how to create dictionaries, access the elements inside them, and how to modify them depending on your needs. The output should look roughly like this.In this article, you will learn the basics of dictionaries in Python. It stores all the information in Extended Properties, so it's easier to keep the documentation in sync with the database as it changes. Run your class by choosing Run as Console Application (F9). Data Dictionary Creator (DDC) is a simple application which helps you document SQL Server databases. Save and activate ( Ctrl+S, Ctrl+F3 ) your code. INSERT ZACCOUNTS_XXX from table result in console If you are working with data dictionary information within formal metadata, there are a number of tools that can help. If you have entered a description of your fields in Design View, they will carry over to the generated data dictionary here. Now you should see the Documenter dialog box. "Delete possible entries insert new entries To generate a data dictionary from MS Access, select the 'Database Tools' tab, then select 'Database Documenter' (under Analyze). ( client ='100' account_number ='00000003' bank_customer_id ='200003' bank_name ='Commerzbank' city ='Nuernberg' balance ='150.00 ' currency ='EUR' account_category ='02' lastchangedat = zv_tsl ) ( client ='100' account_number ='00000002' bank_customer_id ='200002' bank_name ='Sparkasse' city ='Schwetzingen' balance ='500.00 ' currency ='EUR' account_category ='02' lastchangedat = zv_tsl ) ( client ='100' account_number ='00000001' bank_customer_id ='100001' bank_name ='Volksbank' city = 'Gaertringen' balance ='200.00 ' currency ='EUR' account_category ='01' lastchangedat = zv_tsl ) (Generally, you would not do this, but it is useful for test purposes.)Ĭopy DATA: lt_accounts type table of ZACCOUNTS_XXX. Your database tables will be created in any database supported by the ABAP server.ĭeliver圜lass : #A = application table, which stores master data and transaction data (default)ĭataMaintenance : #ALLOWED = allows users to enter data manually in Table Maintenance (transaction SE16). There is no need for any code to define the data in the database, nor for any vendor-specific code. Home Developers Resources Dictionaries Documentation 1.0 Create a dictionary From this section you can create a dictionary: After selecting it, you will see four possible fields: New dictionary name: the name of the dictionary, how you will identify it, both in the dashboard and when used. When you activate the table in the Data Dictionary, the table is created in the underlying database. Tables are defined independently of the database in the ABAP Dictionary. TableCategory : #TRANSPARENT = your table represents a table in the database. Your table contains both character-type and numeric-type fields but does not contain any deep structures (such as a structure included within a table row).Ĭomplete the other settings as follows (or copy the code below). Then choose #EXTENSIBLE_CHARACTER_NUMERIC from the dropdown list. semantic attributes such as reuse of translatable column headers or a check table, but a suitable one does not exist yet. If the data flow is on a logical diagram, the name should identify what the data are (for example, CUSTOMER. Input and output analysis forms contain the following commonly included fields: A descriptive name for the input or output. You often define the technical attributes of the data element in a domain, so they can be reused.Ĭreate a new data element: If you want to reuse the benefits of data elements - i.e. An important step in creating the data dictionary is to identify and categorize system input and output data flow. You can define properties such as search help and (translatable) column header, and then use the same data element in many contexts. Use an existing data element: The most powerful: A data element describes both the technical and semantic attributes of a field, such as a currency, or a customer name. For more information, see ABAP Keyword Documentation: Predefined Dictionary Types. There are 3 ways to create a field for a database table:īuilt-in type: The quickest: You specify a (pre-defined) primitive type, length, and description, but no more. First you need to understand your options: In the next step, you will define the table fields.
