Five steps to rapid advancement with tierdeveloper 4.0 - software

 

Follow the steps below to briefly design, generate, and organize a great portion of your real-life N-Tier application.

STEP 1: HAVE YOUR File READY

1. Coin your folder in Microsoft SQL Server, Oracle, or DB2. You can conceive and construct your own database. Or, you can use the appraise list provided with TierDeveloper. Or, you can use one of the databases/schemas previously provided with your database. They are:

a. Microsoft SQL Server: Northwind database. Just conceive a new TierDeveloper assignment aligned with this database.

b. Oracle: DEMO plan with EMP, DEPT, BONUS, SALGRADE, and other tables. Just construct a new TierDeveloper development alongside this schema.

c. DB2: Appraise representation provided with DB2. Just build a new TierDeveloper cast adjacent to this schema.

2. Populate file with data. This would guarantee that you have a fully running list ready to be used by a web application.

STEP 2: KNOW YOUR APPLICATION'S List INTERACTION

1. Identify table-columns your app will access: Ahead of you do anything, you must know which tables and which columns in these tables is your appliance going to access.

2. Identify transactional operations: Associate where in your concentration you need to do insert, update, delete, or single-row choose operations.

3. Identify queries: Most applications need to retrieve album of rows from one or more tables in the database. Categorize all sitting room where you need to issue queries. These could be single-table queries or could affect complicated joins or nested queries.

4. Identify stored procedures to call: If there are any stored procedures that previously exist in the list which you need to call, categorize them here. These stored procedures must be those that contains composite commerce rules or other data exploitation logic. Do not manually coin stored procedures in the file for transactional operations or for queries that are or else handled by TierDeveloper. TierDeveloper can breed stored formula DDL for you in that situation.

5. Identify bulk updates or deletes: Most applications do not call for bulk updates or deletes but some do. If you have any, ascertain them.

The best way to absorb your applications folder interaction needs is to be au fait with its activities from the user's perspective and focus on all the data that needs to be displayed to the user or altered by the user.

STEP 3: Coin TIERDEVELOPER PROJECT

1. Connect TierDeveloper to your database: TierDeveloper uses OLEDB to associate to your file and reads its diagram so it can let you delimit the mappings of middle-tier stuff with tables in the catalog (based on what you have indomitable about your application's interaction with your database). Choose note that even if you're going to create Java/J2EE claim that will use JDBC to fix to the database, TierDeveloper (the product) will use OLEDB to bond to your database.

2. Define data balk mappings to your tables: Where you had identified table-columns that your attention needs, classify data stuff mapped to these tables with the fitting columns preferred as data be against attributes. You can map a data be against to free table or many tables. You'll need multi-table data stuff for situations where you're annoying to issue a multi-table join query that profits data from manifold tables.

3. Specify transactional methods in data objects: Based on what you identified as your application's transactional needs earlier, you must now delimit those insert, update, delete, and single-row choice as methods of your data objects. TierDeveloper lets you do that with point-and-click.

4. Define queries as data aim methods: For each query that you identified earlier, characterize a query approach in the correct data objects. Remember, a query profits a resultset which get translated into a assembly of data items by TierDeveloper generated code.

5. Define stored method calls as data be against methods: Where you looked-for to call stored procedures, you need to classify data be against methods for them. Remember, these stored procedures confine chic big business rules. Any stored procedures for transactional operations or queries can be generated by TierDeveloper so you do not have to manually write them in the database.

6. Define bulk update/delete operations as data aim methods: Where you need to do a bulk bring up to date or bulk delete, you'll need to classify data article methods for them.

STEP 4: Engender AND RUN 50% OF YOUR Appliance INSTANTLY

1. Generate data objects: After you have distinct all your data objects, you are ready to cause code for them. You can cause data article code in the subsequent format:

a. . NET components

2. Build and arrange data bits and pieces generated code: If you android has the apposite build ecosystem for your platform, TierDeveloper asks you whether you want to build the generated data matter code. If you say "yes", it creates the following. It also then deploys them to your apposite environment.

a. . NET assemblies for . NET components. They are deployed because of constituent services.

3. Generate web application: After you have generated and build the data objects, you can cause a fully functioning web application. The drive of this web appliance is to let you test all the functions of data objects. This also serves as a good sample/example code for you to copy into your own web attention development. TierDeveloper generates the subsequent types of web applications:

a. ASP. NET pages in C# or VB. NET and with or exclusive of XML/XSLT.

4. Build and install web application: TierDeveloper can also build the web pages for you. It does the subsequent for each platform:

a. Build a . NET assemblage for ASP. NET pages. They are deployed to IIS

5. Run deployed web app with data objects: Now that you have productively deployed the data matter and the web app, you can run the web app. The actually nice thing is that all this generated code is now effective anti your own catalog and in your own environment. You can see all the conduct of the data matter all the way through this web app and also use it as a guide in your own web development. Try this and you'll be converted about TierDeveloper being a true Rapid Advance tool.

STEP 5: Acquire Left over 50% OF YOUR APPLICATION

After administration and verifying that all the generated code contains your much loved functionality and runs exactly anti your database, you are now ready to build the rest of the application. The areas you are liable to need to advance in your claim are:

1. Presentation Layer (Web Pages): Use TierDeveloper generated web app as a sample/example for abruptly budding your own. You can even copy/paste a lot of the code from the generated web app into yours, in that way speeding up your advancement work even further.

2. Business Objects: Even if TierDeveloper generated code contains all your data operation logic and some of your commerce rules as well (in the form of data corroboration or stored method calls), you will most expected have to acquire bonus commerce objects. If you're not an knowledgeable in your aim platform (. NET, J2EE, or J2SE), you can learn from the generated data stuff as your affair matter are liable going to be in the same location and would be a consequence alike blueprint approach.
