Main stages of the development DB

The Development database is split on the following main stages. Are they Below brought main points, which can differ for concrete development (for instance, a part 4).

1. Development, statement TZ and selection under it ready parts
   1. First go, it is necessary to define, for what in general needs this base and clearly formulate her(its) problems
   2. If you not specialist in application domain, for which create BD (that usually and can be), that without fall formulate the customer all questions, answers to which you and he wants to get by means of database. Finally must be preliminary tech. task on development
   3. According to TZ create outlines of the reports, which wanted get and confirm them with customer
   4. Select amongst others, earlier created project ready (standard) of the form, which you already use for entering data. After approving with the customer, import them in new project. Thence follows the important conclusion: Than активнее you will use the standard objects (the standard forms, reports, modules t. d.) at development BD, that at more compressing periods you pack.
   5. Searching for and analysis already existing ready decision other developer
   6. On measure of revision TZ will begin be formed list necessary data. Knowing this, possible define, what actual data follows to save in database and on what subjects are distributed these data. The Subjects must correspond to the tables, but given field (the column) in these table.
   7. On the grounds of got by TZ, define time of the development in forehead/hour. If this work on order that also gets cost of the work: Cost of the work = forehead/hour * cost forehead/hour, where cost forehead/hour each defines for itself itself
   8. After final co-ordination TZ with customer formation and signing the agreement by both parties
2. Determination of the necessary tables and relationships between them, flap of the tables and key flap in BD
   1. According to TZ and p.1.5 whole information is split on groups and on minimum logical components
   2. According to list by necessary flap and groups given required tables with corresponding to him fields
   3. They Are Defined key fields of the tables (internal and external keys)
   4. Are fixed relationship between table, is built scheme data
   5. Tables are filled minimum required for analysis of the structure BD volume demo-data
   6. It Is Conducted analysis of the got structure BD, are corrected possible shortages
3. Designing the interface of exhibit
   1. According to TZ and p.2 the necessary objects a database requests, the forms, reports, modules.
   2. It Is Conducted analysis (preliminary testing) of the work of exhibit and if required shortages are corrected
   3. In the event of turned out to be impossibility to realization what or points TZ and other departures from it, this question is elaborated with the customer.
4. Testing, creation to documentation, delivery of the project and calculation
   1. In the event of installment payment of the work, on measure of the execution p.3 customer is seasonly returned on study, preliminary testing and statement, separate parts of exhibit in demo-mode, and according to agreement occurs the partial payment of the project.
   2. After final making the project is conducted his(its) full testing
   3. S documentation (reference) on program
   4. The customer leaves Under successful passing all test program in demo-mode for final familiarization.
   5. The balance is Produced according to agreement, after which customer leaves the full version of the program without what or restrictions
